Hi

I'm using Li-Ion (18650 cells) 48V (13S) 990Ah battery on my Axpert VMIII.

What is the best setup to protect the battery ? 

Thanks

 

Hi 87

Thanks for your answser.

Can i set parameter 26 "Bulk Charging Voltage" to 54.6V (4.20 per cell) and ask to inverter to go back to battery mode parameter 13 at 52V ? Battery won't be charged more than 52V ?

Parameter 12 will be 44V because i can't go under.

I can wait on battery 1 week 😉

Each block of 300 cells haven't got more than 0.003V difference voltage between themself in the pack, i'm using 4 active equilibrer 6A because the equilibrer inside the BMS is not strong enough.

All cells are the same and have the same caracteristics, it's like 13S300P  😉
