LifePo4 Charge Performance
Thinking seriously about replacing our two GC2's with a pair of 100ah LifePo4's. Hearing a lot of chatter about how lithiums accept a charge much quicker than lead cells. Very familiar with how ou...

“ This could be from wiring inverter to bank, but more likely low 120v voltage input to the charger. I see that at home where my converter will still operate with the long extension cord from the house, but it does lower amps than usual and the input voltage is below the required 105v specified.”
I have a 6’ round trip run of 0004 aught to the inverter...The ProSine charger is programmable, but since making the swap to Li, I’ve yet to bother with any nagging reprogramming (lol) - as is, the voltage tops out at only 13.7 while the PD (for completion, on boost) is at about 14.3v...
Having said this, understand that with Li, except for an occasional cell balancing, it’s no longer my priority to ensure the battery is fully charged upon trip departure (as would be the case for FWC)...I store the battery at about a 50% SOC (to keep + & - ions in approximate equilibrium), a often begin our trip departure with just the 440w of solar alone... This strategy typically gets us to our favorite OHV spot (trailer in tow...) at about 70-80% SOC (as charging continues...) which is quite sufficient for our several days of outing...It’s in this way that I MIGHT only need shore power for an occasional cell rebalancing, but have yet to use the generator for this task...
Another advantage here is that I haven’t had the need to wrestle the Honda 2200i from it’s uber tight storage compartment...Running the 11kbtu roof-top *air for an hour or two duration via inverter (concurrent with harvest) is quite doable, especially now with so little Li voltage sag...
