<p>Hey Folks,</p>
<p> 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.</p>
<p> I found this at their website:
<a class="moz-txt-link-freetext" href="https://simpliphipower.com/product-documentation/">https://simpliphipower.com/product-documentation/</a></p>
<p>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.</p>

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