I have a Luna 2000 5kWh battery module and have found it difficult to get any definitive advice on how so set up its charge and discharge limits.

The advertising blurb states its uable capacity as 5kWh but Im wondering whether it is wise to charge 0-100% from a longevity point of view.

At present I have it set to 20%-100% and last winter had it 5%-100%. Obviously i would like to get the maximum I can from it but also prolong its life as much as possible.

Any ideas? thanks

No suggestions for this?

If we talk generally about LiFePO4 batteries and I wanted to get the most capacity I could without compromising the batteries longevity would 20%-100%, or 10%-90% be better? could I go to 5%-95% without problems? Thanks in advance
