Hey Folks,
From the SimpliPHI/Outback integration guide download,
using an Outback (I assume any brand of) charge controller (EG: FM80,
FM60, FM100), their chart shows absorbtion voltage at 56.4 for 51.2 nom
PHI batteries with time set at 6 minutes, page 18. If using the
inverter, they show 54.0 volts for 2 hrs, page 13.
I found this at their website:
https://simpliphipower.com/product-documentation/
then scroll down. There may be a longevity advantage to not fully
charging L-ion batteries but if you're only charging to 80% and not
really supposed to go below 20% SOC then L-ion batteries aren't looking
much better than FLA batteries in terms of capacity.

There's no benefit to charging to 100%. If the charging parameters are
set up correctly, you'll never really get to 100%.
If you look at most prismatic cells, the absolutely maximum voltage is
3.65V. My systems are set up to charge to 3.4V or 54.4V. I take that
as 100%.

I have a client that insists it is better not to charge lithium
batteries to 100%. Is there any truth to this?
Thanks,
