Hi Mike, I noticed that in your Li article you are using a Zamp Li charge controller…I tried out the same controller on a 100amp LiFePo4 and found that it tended to top out at about 93-94% of SOC. I called a techy at Zamp about this and was told that they’d worked with BattleBorn and this is what they came up with as the best SOC algorithm…
However, I recently watched a clip on Youtube by BattleBorn and they said that in order for the BMS to properly balance the cells, the Battery needed to be restored (at least briefly) to 100% SOC…FWIW, we recently switched out to a MPPT Li type controller (but not necessarily for the above reasoning) and noted that it allows for a 100% SOC algorithm…

Just curious about this…So are you then saying it’s normal for the Zamp not to reach 100% SOC?
Thanks, Phil
Thx Mike, the LiFePo4 battery and charger findings I mentioned are on my neighbors cargo conversion rig that I’ve helped him build (I’m still using old school heavy 6v wet-cells)…
Post build I’ve been steadily experimenting and gathering data to better understand his Li battery characteristics (though not BattleBorns)… After having tested battery performance with various kinds of reactive PSW inverter loads (with truly remarkable results!), and stable voltage throughout the discharge cycle (great for motors…), based on performance alone there’s little doubt my next battery will be Li…I also note that the 120a Expion’s with their serviceable BMS are pretty impressive indeed…
