Glad to help.

Go for it! I'm over 65, I rode my ebike 700+ miles last year. I love my ebike so much, I keep it inside my residence. I have degenerative disk disease, and arthritis in my legs and back. Ebikes have allowed older people to get out and pedal. I just bought a new ebike last month, and I'm getting another new one soon. Ride safe!

Yes I get review bikes from time to time and get to keep them. Glad to help.

Thanks Wood!!

Yes that’s what I figured. A lot of people think they know what they need to know but they really don’t know what they should know 🤜👍✌️

@@TheFrickinShredder I'm one of the ppl that didn't know that I should know the battery stuff..and it helped me understand battery's. Esp getting the watts. Thanks again. It's 90 degrees in kentucky. 100% humidity. Summer started faster than normal here.

Enjoy the weather and glad I could help. 🤜

Appreciate it. My pleasure. Glad to inform.

I guess it's kinda randomly asking but does anybody know a good place to stream new movies online?

@Conor Leroy Flixportal xD

@Emmitt Dariel Thanks, I signed up and it seems like they got a lot of movies there :D I really appreciate it!

@Conor Leroy You are welcome :D

Thx! Appreciate it!

You can definitely pop a new battery in after a long ride and continue.

Appreciate the support. Glad to help.

Hello Aysa，May i know the controller is 36V or 48V ？so we know which battery fit for your bike

500-600 wh = 18-20 miles, 700-800 20-23 miles, etc.

Thx! Probably 40+

Oh cool. Glad you found it. Thx. Glad I could help.

You’ll get max 22 miles or so

Glad it was helpful!

@@TheFrickinShredder i have question, if my electric bike with battery capacity 36 Volt, can i replace with another battery with higher voltage? For the example i will replace with 48 V or 52 V, it is safe?

Thanks!!. Not ideal. You could I suppose if you had the same battery connector and housing forthe battery.

@@TheFrickinShredder IT's highly doubtful his cheap controller would allow two different voltages to be used.

A 36V battery's maximum voltage is BELOW the minimum cutoff voltage of a 48V controller (usually coincidentally set to 42V). Thus a 36V battery won't work *_on an ebike setup for using a 48V battery_* SOME controllers may let you change the ebike's voltage parameter to 36V on the fly (eitther manually or via an "voltage autosense" feature), but many do not. Even if you have a dual 36V/48V controller, it still may not let you change the voltage on the fly and the 36V battery pack would remain useless. It shouldn't hurt the electronics to try using the 36V pack on a 48V controller, but even if it does work, your bike may act quite differently than it does when running on a 48V pack.

Sorry man. You’re way beyond me technically.

@@TheFrickinShredder 🤣🤣...and I promise my knowledge is very limited, bro. self taught and still learning problem by problem. Figured Id just reach out to someone. Thanks for reply. And for great video. /bklyn 👑

800wh would be good

No need. Just charge it up.

😃

It depends on the battery but typically a 72v battery can go down to about 63v. A 48v can go down to about 41v.

Appreciate that

Sure you can but you’ll need a separate controller most likely unless you can figure out how to get a single controller to feed power to both.

I would think so. Amp hours are so similar the controller wouldn’t likely have an issue.

Pretty much.

@keepsmiling1484 said, _My question is, can I use a 36v battery on a bike that originally came with a 48v battery?_ Generally, no. The reason is that the 36V battery even with a full charge, is already at or below the minimum voltage the 48V ebike's controller will allow to be used. The controller's are designed to cut-off the power from the battery pack once it reaches the lowest voltage the battery can be depleted to before it causes damage to the battery. For example, a "36V" controller usually sets the battery pack's minimum safe voltage to ABOUT 30 Volts. A "48V" battery pack's minimum safe voltage is set to ABOUT 42 Volts. It should be noted that while the REAL safe voltage for modern lithium-ion cells may be a bit lower than those I provided above (eg a REAL 27V for a modern 36V battery pack), the controller programmers are providing a buffer in the "minimum safe voltage" to ensure the voltage isn't taken down too low. Older battery packs had higher minimum safe voltages (eg a REAL 30V for an older 36V battery pack). The impact of using a battery pack below the minimum safe voltage for that pack can be PERMANENT instantaneous damage to the battery, reduced lifetime of the battery, reduced number of recharge cycles, reduced voltage, reduced Amp-Hour capacity (which in turn means from then on you get fewer miles per charge), and even potentially catastrophic destruction of the battery including fire and/or explosion. So, the programmers make sure the ebike will turn itself off before the battery falls below that minimum safe voltage. ------------------------------------------------ Edit to add: Also, in a world where manufacturers may use cheap lithium cells, counterfeit cells, and/or counterfeit Battery Management System (BMS) circuits, one cannot rely on the safety methods and devices working. So the controller programmers add that one extra layer of protection to further reduce the chance of battery pack damage/destruction.

Buy a new one from RadPower

All batteries now last for years. I’ve had e bikes for several years and batteries last last last.

Sorry don’t know. Haven’t had the sinch for over a year. Sold it.

I’m not an expert on batteries. I just did a lot of research. However I believe you can get a standard 48v battery with as many amp hours as you want. You can even consider a 52v battery.

48 or 52v. At least 18ah

50 amp controller with 2,000w motor should have some nice torque. Not crazy but nice.

@@TheFrickinShredder Ok thanks, better to switch my 34 amp controller that came with the 2k motor for a 50 amp ?

Indeed

@@TheFrickinShredder Thanks

Hi there. Thanks for reaching out. Unfortunately I didn’t do extensive research on specific battery products. Wish I could help. 🤜

I would stick with 48v for a bike that size and weight. You might need a new controller with a 36v. Everything I read says to run a 36v battery only with a 36v controller. So you could run a 36v in parallel but you’d prob need a separate controller. Check out spark Cycleworks they have a battery blender that might help.

@@TheFrickinShredder I appreciate the reply, i guess i'll be waiting for a price drop for the 48v's

I wish I could answer that question for you but it’s beyond my level of understanding. Sorry. My understanding is one battery per motor. But I could be wrong. Good luck with everything. I wish you well. You’ll love ebiking!!

@@TheFrickinShredder The battery BMS will only allow the maximum amp rated for battery safety. In his case it's 50amp, which means the controller would output 50amps and each motor would be inputting 25amps each from the controller.

You would need to look at the specs for the battery. Many times a 50 amp BMS will allow 50 amps continous. Usually there is some higher amperage allowed for shorter periods of time. That might mean a hard acceleration could be sustaiined, but a long term high load (very long uphill) might have the BMS shut down. Some BMS will reactivate when the load is removed. Others need to have a voltage input into the charging or the main leads of the battery to wake them again. It is best to have a battery capable of the highest sustained load of the motor or motors. Or use two batteries each of which can support the attached motor. For example I added a front hub motor to an eBike that had a rear hub motor. I used two batteries for that bike. When I gave it to my son, I put in a heavy duty 48 volt battery (front motor was 48 volt) and a step down converter to 36 volts for the 36 volt rear motor. The battery pack was capable of providing 200 amps so it was not the limiting factor. My current eBike has a Cyclone motor that will run on any battery from 48 volts to 84 volts. I have used various batteries on that bike. Currently I have a 72 volt 15 amp hour on it for 30 miles of range at 10 mph. I have a numerous additional batteries I can carry along if I need more range especially riding woods trails or the beaches.

Try to stay between 20%-80% at all times

If I look at the chart on your video 20 percent is equal to about 42 volts is it correct?

The motor changed the torque and top speed. The difference between a 48v and 52v battery won’t change power but doubling the motor will have a substantial impact on power and speed!!!

@@TheFrickinShredder Wups I wasn't quite clear...how will that impact the battery? Will the additional outpower reduce distance? Only if I'm going full speed? Hard questions thanks for the response btw.

I see. Yes the bigger motor will impact range but you’re also getting a battery with double the amp hours so all should be equal.

200ah are sure it’s not 20 ah?

You should say easy get 20 miles to the gallon equivalents

As long as the voltage is the same, it would work. For the battery, more Amper/hour it has, better it is.

@@gsteshen so i cant buy a 72v 19ah battery for my 48v 1.5kw kit with 80amp controller?

@@MrTapsa. Did you learn how to read? "As long as the voltage is the same..."

@@gsteshen i did my research and u can use it so..

I appreciate the question but I'm really a battery technology generalist and don't have specific product recommendations. Wish I did for you. 🖖

Sorry man. Beyond my preview. Not sure if this helps. electricbikereport.com/volts-amps-and-watt-hours-battery-numbers-explained/

I have same problem if you get higher voltage you get more efficient and use less amps but you actually will use about the same cells but you will be way faster so you can make have more range in less time if you use a 72v motor if you go 48 you will have less velocity (we talking the same watts our a battery capable of 2000w per hour) so it will be slower less efficient and less Range with for a 1000w is okey 48 for 2000 is better 60 or 72 less is not good 1000 w motor ar nominal power it means commonly the motor brings that power but in reality a 1000w motor brings 1500 power in some moments of high consum so 2000w can make more power in some moments a 48v 20amp battery is not meant to feed a 2000 motor in full speed you could use it but at less than 80% of its power its complex you must have a bms capable of allowing enough amps to the motor and good cells 2000w with 48v needs 41 amps per hour

@@leonardolarocca1999 Thanks for such a great information. I already got new battery 48v28.8ah 50 BMS. Motor 48v2000w45A BMS and max speed 60. I think I made right choose. I

What do you mean by max power?

@@TheFrickinShredder thanks for reply..sorry I meant voltage, 46v/52v etc

Sorry Kevin, I don't want to steer you wrong. It sounds like you're putting too much power through to your motor or battery.

@@TheFrickinShredder hi thanks for replying that did cross my mind as well. is there any setting in my display that would help with the problem I could alter the controller I’m using is 48v rated current 22A maximum current 45+2 thanks Kevin

​@@kevinneal5719your controller should support 52v get a different controller

Glad I could help

You'll get about 5 more miles out of the 48V

Not necessary

@@TheFrickinShredder thanks mate. I'm loving your videos. Great insights. I bought a converted e-bike with a 3 pin yose battery. Should I wait until the battery goes to the last dot/ bar (red) before charging?

Manufacturers say you should go down to 30% the first five times then after that it doesn’t matter. Thanks for supporting my channel!!

Sorry. Not sure.

Thx Brian! 💪

I’m not sure hours but range you should get upward of 60-70 miles. That’s a big battery

@@TheFrickinShredder ohhh ok thanks

Best bet is a second battery to carry in a backpack or rack. If you increased your battery size you’d have to increase your controller as well and it might be too much power for the motor.

@@TheFrickinShredder how many volts and ah should i use?

Get the same battery it came with

Adding batteries in series do not change the amps, its stays the same which means 20ah.

You can upgrade the battery but to get full power out of it you may need to also upgrade the controller.

@@TheFrickinShredder definitely need to upgrade controller…or you might have some problems. Your controller may be a dual controller like mine, i,e, 36/48v controller or 48/52v controller, etc. Check specs first. imo, ALWAYS purchase the most amp-hours you can afford for your battery configuration….you’ll thank yourself later. Personally, i only buy ebike batteries with a minimum of 20 amp-hours. Long term investment. /Bklyn👑

​@@kyriegospeldon't forget to change the wires!!! Get thicker gauge for 72v at least 6 better 4

Motors are rated in watts.

@@TheFrickinShredder so u can use a 1.5kw hub motor (48v) with 72v battery?

​@@MrTapsa.Yes. The motor will just take it. But not too extreme, it would be better to go a lil bigger on the motor anyway to get the most out of your system. To be safe, unless you're an educated ebike builder, pro or amateur, just match the volts with all your components. Motor, battery, controller

No won’t work

It may but you’ll Likely need a higher powered controller

They’re the same thing. Regardless, you don’t need to know about that.

@@TheFrickinShredder ok it's a bit confusing when trying to buy a bafang kit and you can choose between hailong and downtube

Batteries do degrade over time. Your seems to be having problems kind of early but it does sound like a battery issue. See if it’s covered by warranty.

Almost certainly

Agreed. Just don’t buy Chinese junk.

@@TheFrickinShredder Racist nonsense - It depends on what make and what supplier - their are some excellent batteries from China but also some fake claims

Hello Calvin，the battery speed effect for power of motor.48V 13Ah and 25Ah is the same speed. the biger amp hours can go more range.

@@cherrylin7449 Oh, ok! And what about if it's declassified can I still use the pedals and throttle as is, or just the throttle because the C961 display has 3 modes ( Sport = Throttle, ECO Mode= Pedal Assist, and Walking Mode ). How would I be able to switch between the 3 modes in which I might need to use 2 modes ( Sport, and ECO ).

It depends on ur controller continuous amp draw and battery bms, but you can. Make sure not to use higher controller amps on lower battery bms amps

Appreciate it

There's a big difference between them, mostly depending on the controller it's paired with, But having used both with equal amps output the 52v will act more peppy for much more of its capacity, you know how your bike feels when it's fresh off the charger?, it's nice but it fades very fast, well a 52v will feel like that down to 25-30%. also keeping the volts up keeps the amps down, as your 50amp controller for example will pull 50amps at 58volts(2900w) and 50amps at 45volts (2,250w). This is the basis for why that one extra cell series makes a big difference. It keeps the controller fed with optimal voltage for longer.

@@a-aron2276 exacly its just better same with 60v vs 72v

48v vs 52v is one more battery per pack lol it ain't much

Couple more miles range maybe
