600w 10A charger safe to use on 48v LifePO4 12ah pack?

[cix]

Is a 10amp charger safe to use for a quick charge? on some LiFePO4 cells it says max charge current is 3C. What does C mean and is this over my amperage? i assume the 10amps is going across all cells, i believe my pack is 15 cells.

Can someone shed some light please?

If your cells are 12Ah at 3c, you can change at a MAX of 36A.

If you are charging through a BMS circuit, your BMS must be able to take 10amps. I know the ping BMS can only take 5amps, as it will get too hot and burn up.

The 40amp BMS cell_man provides can take 10amps as far as i know.

I don't believe i have a BMS. Just gonna charge battery pack directly via Anderson two pole connector. I just hope the vendor doesn't screw up the polarity.

if your battery was built by a battery maker it will have a BMS. they could not sell batteries without a BMS because the failure rate is so high they would lose money on returns.

if you don't know what your battery has then you should find out. do you even know the battery manufacturers name? or is this just an ebay nameless agent selling some other manufacturers battery?

It will have a BMS. If it's not from cell_man, and you have no idea what the bms is, you will be safe with a 2amp charger and probably a 5amp charger.

2amp charger will take 6 hours to charge when all the way from empty.
