I'm new to LiFePO4, so just want to make sure I get my Magnum Energy inverter charger setup correctly for these batteries. This is all installed in a large 5th wheel.
Setup
Magnum Energy MS2000 (2000w inverter and up to 100A charger)
ME-ARC Remote
ME-BMK battery monitoring kit (shunt)
A pair of SOK 12V 206 AH batteries in parallel
All 4/0 power wiring
Shore power and generator power only (no solar)
Based on some videos I found during my research, I've selected the battery type as "CC/CV". The ME-ARC does not have a lithium-specific profile preprogrammed. Here are the settings I'm using within the CC/CV profile:
Max Charge Amps - 80A
CV Charge Volts - 14.4
CV Charge Done - I have the choice of "Time" or "Amps" here. I've set it to "Time" and 1.5 hours.
Max CC/CV Time - 8 hours
Recharge Volts - 13.2
So, questions:
1) Most of these settings are a guess, so I'm looking for any advice you have. I want to get the most from my new batteries, but also need to take care f them.
2) How do I know for sure when the batteries are fully charged? The inverter charger tells me they are, but is there a way to actually verify that manually? Something like disconnecting them, then checking voltage? It would just be nice to somehow verify if I'm getting a full charge (or whatever SOC is best) when the charger tells me I am.
3) I have the inverter low-voltage cutoff set at 11.0V. Is this safe for the batteries?
4) Any other advice or input I should consider?
Thank you so much for the help!!
