FWIW, my 200a/hr drop-in was at 55% SOC this morning, so for test purposes I kicked on the 100a capable ProSine 2.0 charger (solar OFF) and the amps settled in at about 50a. In about 15 min time SOC is up to 68% - this is just a quickie, back of the envelope’ stat...Sure Li cost more, and it’s strictly up to the end user to determine the cost/value proposition - But as a former 16 yr 6v GC devotee myself (and a mostly desert dry camper), the rapid receptivity rate during solar harvest makes Li the hands down Best option ...as I write this SOC is now at 71%, charger amps running at 50.3a...
Another thing is that for capacity estimation purposes only, I can see no real need to subtract say 10% from the ‘top end’ because this IS truly usable, though I do accept the idea of 10% off the ‘low end’...
