As long as i watch process closely , and use a bms would i be able to charge up diy battery pack ,Without damage ,
Thoughts and comments , Appreciated.
 
LFP is generally a drop-in replacement for FLA/AGM/GEL.

Any charger that does not charge above 14.6V or float above 13.6V is fine for use with LFP.
 
I don't know what voltage the equalization cycle uses .... but it generally isn't good for lithium.
 
Does this have an AGM mode? Those don’t equalize.

In. FLA mode, I have a PWM charger that will auto equalize after one week, and I also have a wall charger that will auto equalize after one week. That sort of stuff is in the owners manual.

no it doesn't , unfortunately
 
I charge my battery with an FLA charger. Works fine. BMS will go to protect mode. Not really the best for an automatic installed system. However for periodic manual charging seems to work fine to me.
 
One other caution about using FLA or some of the vehicular lead-acid chargers, is that some will assume that low-voltage batteries are sulfated, and will start to zap them with 16v "desulfation" pulses to try and force them to accept a charge, which obviously are bad for LFP.

Ie, if you have a very discharged LFP below about 10.7v, the standard fla-charger may start shooting those desulfation pulses out.

So be careful out there if using one of these...
