Need EFlow battery BMS

[JTUWEC]

I'm a newbie here but have enjoyed commuting an EFlow the past 4y. My BMS battery component fried, neither Currie or shops can help. Any sources or help appreciated greatly.

Hi! Are you seeing if anyone has a battery to sell or are you looking for info?

Thanks...either possibly. I bought a new functional battery miraculously from Currie ...currently using. But my spare needs the BMS.
Planning a long trip and want a 2nd battery :/

Thanks for the considered response! The guys at RPE in Vegas and my dealer (Lennys in Madison) are saying it's proprietary :/ and its a 2015 era display push button on-off. Good cells. I found these online below and pinged RPE and Lennys but no reply

Tough without knowing what the size and specs are. I'm wondering how you know it's a BMS problem?
4 years old, could be just tired cells.

Edited to remove earlier reply. OP's story kept changing.

I agree with Thomas. A 4 year old battery is close to it's useful stage. The cells will always show voltage but that doesn't mean there still good. As soon as a load is applied the voltage will drop which is what happens to tired cells.

Thanks both of you. A background: I went hard on a warm day and made a (later found out..) mistake to charge right away instead of a cool period first. RPE put in fresh cells ~8 mos earlier.

If you can't get help from the maker, I'd press RPE a little harder. They require the original battery, BMS and battery charger to rebuild a pack. They supposedly test everything, they should be able to give you some help here. These aren't the days of hand written work orders. One would think there are records of the work performed. If not for the customer, for other future rebuilds. Good luck!
