Schwinn World Electric bicycle battery question

[Jason27]

I recently picked up a used Schwinn World Electric bicycle and I would like to replace the battery.

Part# BP-L2410EH2 or 7ACCAMBTA.

From what I read the battery uses a 29 volt pack. Does anyone know if the bike is compatible with 24 volt or 36 volt batteries?

Thanks.

24v pack would charge to 28-29v. Sounds like a "24v" to me. It may or may not run fine on 36v, that charges to 42-44v.

If you can look inside the controller, you can see if it has 50v caps, that would allow for 36v use. Some 24v controllers will have less expensive 30v caps.

The battery is a 7s lipo battery pack. I don't know if the controller has a built in voltage limiter, but it would be easy to find out. string 3 12V batteries in series and see if it works.

I'm afraid using a 36 volt battery. I dont know if the controller can handle it. I can't tell what the max voltage is. No voltage caps on the outside.

You can use any standard 24v battery.

Every 24v controller that I've tried has been able to to take 36v, but of course you'd lose the low voltage cut-off, and any battery-level indicators would show full all the time.

If it were mine, I'd use the opportunity to upgrade the whole system except the motor - battery, controller, LCD., PAS and throttle. The controllers aren't that expensive, nor the other stuff. You'll have to change a few connectors etc.

If you get a 36v rack battery from BMSBattery, they have a nice range of controllers and display panels. You need to check whether your motor has hall sensors to choose the best one.

Open the controller to see what is the limit of the caps inside. Bet that's not so easy to do, likely pretty buried. Takes an hour just to see the controller on my Ford think. But that's expected, from a car company.


I wouldn't hesitate to take it to 30v fully charged at all. 8s lifepo4 is fine, 7s limn or lico is fine. For sure, the caps are at least 30v.

Did the OP ever have any luck repairing this pack?
I'm sure 30v (SLA or other) would be ok, even for the 180W motor on the Global GDS I just picked up - but i too am cautious of trying 36v and not frying something.
I also am in need of a key to energize the ESC - in the meantime I am hot-wiring a lead into it so I can at a minimum use a 24v SLA pack until I find parts or someone to rebuild the original ( BP-L2410EH2) pack.
Any updates in another thread? I'll need a 30v 2A charger as well if the internal electronics are still good.
