DIY LifePo4 Battery Build
Was right on the edge of purchasing a pair of 100ah BB or LifeBlue LifePo4 batteries ($1600-$2100) for our truck camper. They were going to replace two GC2's. About 2 weeks ago decided to get advent...

IMO this standard converter is a better match for our battery pack than the single-stage Progressive Dynamic dedicated Lithium 45a converter which produces a constant 14.6v. As per BattleBorn Batteries, if a 14.6v single stage converter is inadvertently left connected to fully-charged LifePo4 batteries for weeks, months at a time it can overcharge the batteries. No such concern with our converter.
If there's still concern, one has the option to set the high voltage charge cut-off in the BMS to any value to want with a DIY build. You could even set it to 13.2v if you like. With good BMS presets, it's almost impossible to damage the battery.
