More on LFP Charging
Some "sales" statements here, but also some possibly good info of interest. One thing is they found longest life (most cycles) was to charge at 14.4v but at lower amps at 0.3C. Some LFP owners o...

I have a 100a pass-thru charger and a PD 9245 - the highest combined amperage I ever witnessed is 82a (usually a bit lower as it tapers down), this feeding into 400a/h of LFP (cylindrical cells = air gaps), mfg’s ‘C’ rate is 1.0, but I can’t even get close…With just the lowly PD, I can’t hardly imagine exceeding most other mfg’s C rate…

I’m running 0004 / 3’ cabling with crimped, silver soldered lugs…I think it has to do with at what SOC point I begin the charge, but it’s pretty much inconsequential to me since I mostly use solar and ‘play’ somewheres in the 60-80 % SOC range…No doubt, internal resistance plays a role…
