52v 25ah Batteries with Smart BMS? Where to buy or have built?

[ElectroWoodGuy]

I need to replace the UPP 52v 24ah battery I have. Battery appears to be working after I discovered the wrong charger was sent, a 4a 54v charger.

Hooked up a 5a 58.8v charger and battery charged from 35% to 80% in 90 minutes.

That said, I’m worried with charging and heat being a UPP battery.

Where can I find or have someone build a 52v 25-30ah battery with a 40a smart bms? Can’t be more than 78mm thick.

If you can't do it yourself, google "battery cell replacement" in your neighborhood and send your old battery in. If the company providing the service know its trade, they will fix it.

It would be good to know all of the dimensions. 78mm would accommodate the use of 21700 cells, rather than 18650, but the other dimensions would let you know if you could fit 30Ah of cells into the available space.
