Hi everyone, quick question, is there any issues with not charging my batteries to 100%? I normally charge them to a maximum of 60%. Now I’m using D ESS that does very little bit more.
asked
Plyontec Batteries - any issues keep charge levels between 20-60% long term?
They need a regular full charge so the BMS can balance the cells. Failure to do this can lead to permanent damage.
Can you expand on the nature of permanent damage? There appear to be plenty of cell vendors that recommend SOC < 100% so that would be interesting to understand better.
Hi @h2009,
The main issue I would expect is that the state of charge becomes less accurate over time.
I would do a manual recharge to 100% once a month or so.
That process would also give you hints if the battery cells are going out of balance over time (as the battery will not reach 100% until they are pretty close).
Lithium batteries are far more tolerant of cycling anywhere in their 'safe range' between 10%~90% than lead acid, but old habits die hard :)
