My AGM to Lithium conversion

You say the recharge went from 60%-100% in 2.5 hrs at 30 amps. That is 2.5 x 30 = 75AH NOT 40AH. So again that 60% SOC must be wrong. You were down to about 25% SOC it seems from that.

You might be right with this observation because I wasn't sure the Aili monitor was reading correctly at first. The only other variable that would affect this test was ambient temperature. The ICECO refrigerator was in a 55 degree garage only looking for 40 degrees. While with the AGM battery we were in summer outdoor heat of 80-85 degrees.

I'm going to modify the article so there is no confusion.

Thanks for your input....
