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...

Excellent! What are you charging with?
We use the standard 3-stage, Progressive Dynamic 45a converter in our truck camper. Use a Charge Wizard to lock it into bulk 14.4v mode for a fast bulk charge, then manually drop it to 13.6v when charging is complete. It charges this pack to 100% SOC with zero issues. It produces a full 45a of charge current for nearly 90-95% of the charge cycle. Fast and efficient.
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.
FWIW, we were able to get almost 85-90a of charge current by charging with both the PD 45a converter and our Renogy 40a dc to dc charger at the same time. This pack will charge up to .5C (100a).
Corrected charge rate from 1C to .5C.
