Thank you, I understand.

I have read that some do hold CV, to some % of amps originally put out like 10%.

Or some that have a fixed time, aka eggtimer.

I'm surprised that after several questions, no one informed me about the existence of isdt bc-8s,
I have to thank jonyjoe303 that have informed about it in the forum: This is another monitor isdt bc-8s that also has a overvoltage alarm. This one will alarm on li-ion and also lifepo4, over voltage setting programmable.

CHARGERY BM16, (Negative for me): choose model: lipo or liifepo4, if in the future I take a li-ion battery, the lifepo4 will not go.
So maybe I'll buy 2 or 3 isdt bc-8s,
oo I can charge the 48v 16s lifepo4 battery at 80-95% without bms with more security (with the power supply).

Thanks, next time, I did it so I wouldn't waste time translating.
