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 agree.
I know if I had to combine my solar and Magnum charger it would max around 175a charging (with good sun) and have seen 165a when running the generator one time to see what it would do combined. Makes for some quick charging. ;)
As far as charging I can feed the batteries 100a (.2c) my with the eu2200i till 98% SOC when absorbs kicks in for 6 minutes and tapers to 99% SOC.
I mentioned this in previous post that I could just about put a stop watch to the minute for how long it takes to use the generator to charge batteries to full if need be.
