So there is a Australian business called mullerenergy that sells cells, pre-made batteries with custom box, chargers and bms's.
They are selling a jbd 250a 12v 4s but its on backorder but from what I thought you can only get 250a in 5s+.

I can't find anything on the internet about a 4s 250a from jbd and this business is saying its only available at their business.
Is this a fake or real.. I know the business is legit but is the bms real?
 
There is this one, but it's not 4s.


250 amp 4s would be a 12 volt battery. That would put the discharge/charge very close to 1C. That doesn't sound like a good idea.

That isnt fully the best way to think about it.
If you have 300ah cells in 4s2p. That would be only be about 0.4C

And yes it is real. He has them custom made by JBD for this exact reason, as most people in Australia that are custom building battery packs are using the LF280 or LF304 cells. So if they need to get up to close to 1C for bursts, they now can with the JBD 250A BMS
 
There is a 300A version coming as well.
