The Lithium battery seems to be charging correctly and gets to Storage Mode. My BMV-700 shows 100% SOC but then slowly, under load, drops to somewhere like 90% SOC before recharging (positive amps) restarts. The IP22 is in Li-ION mode and the BMV-700 is all factory defaults except Charge Efficiency is set to 99% and the Peukert's exponent is set to 1.05.
@mark.winship@hotmail.com, this appears to be entirely normal behavior. Your IP22 charger is looking at voltage, not SOC, and your lithiums maintain a high voltage for longer than a flooded bank. Your lithiums aren't dropping to a low enough voltage to trigger the charger until they reach 90% SOC or lower... which is fine, and normal.
Keep in mind that 90% SOC isn't very significant on a lithium bank considering that you can safely discharge to 20%, unlike a flooded bank that you could only discharge to 50% at most. So your 90% SOC on a lithium bank is far less significant than a 90% SOC on a flooded bank.
Good news: everything appears to operating completely normally.
Excellent answer; many thanks; I am still getting used to Lithium batteries!
