UPP Battery - Rectangle 52v - Ok to use?

[ElectroWoodGuy]

I bought my 52v 24ah over a year ago and finally getting to my build. Learned yesterday about UPP Battery and the triangle battery fires. My battery is a blue wrapped rectangle.

The info has me a little nervous. I’ve read only good things about the square UPP batteries, many with 3000km on them.

Any thoughts?

I can’t even find another brand that makes a 52v 22-30ah battery that’s max 70mm thick that’s either rectangle or will fit I my location.

First off is it really 24Ah capacity? You know they use no name Chinese cells that are supposedly A-grade, but no proof of cell capacity or even how many cells are actually in parallel group.

As far as any/all blue wrapped flat batteries they are Chinese with no proof of Ah capacity and no name Chinese cells with
Protection BMS, but no proof of a balancing feature (not that you really need) with A-grade cells and TLC of battery.

CAUTION: You should get your money's worth of use IF you don't abuse it (e.g. pulling max amps for only seconds instead of minutes).

Charge to 80% and then just before using, top off to 100% just before riding on an extended trip. Do occasionally charge to 100% depending on use, to allow your cells to be properly balanced IF that UPP BMS even has a balancing function or just protection functions. Don't discharge below 30% (47.0v 14s (3.3v/cell)

If you bought the cheapest UPP pack where they don't say what cells are in it then there is cause for concern. They do make good packs with reputable cells (LG, Panasonic, etc.) that have a good history. Which is yours?

As mentioned before, I'm surprised at how few people even know what the actual capacity of their packs are.

well some are better then others but I like not to combust even if doing something stupid who sells better cells in packs or is creation the best way I need high draw 60v for a scooter no petals
