Re: [RE-wrenches] Max charge for lithium batteries

You can absolutely charge to 100% and you can discharge to 100%. Lithium is in another world compared to Lead Acid. You don't see LA cars driving around. But you shouldn't leave Lithium at 100% for months on end, it can be detrimental. That's not likely to be an issue for solar systems. Your absorp

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

Re: [RE-wrenches] Max charge for lithium batteries

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%. On Sun, Oct 31, 2021 at 1

[RE-wrenches] Max charge for lithium batteries

I have a client that insists it is better not to charge lithium batteries to 100%. Is there any truth to this? Thanks, Drake Drake Chamberlin Athens Electric LLC Ohio Electrical Contractor’s License 44810 CO Master Electrician’s License 4526 NABCEP Certified PV Installation Professional --
