FAQ

Will the battery be damaged if allowed to fully discharge?

Firstly, the BMS has a low voltage disconnect at around 10.5V, so the battery will never discharge to

zero volts. If the battery is flattened and cuts out at LVD at 10.5V then it can be recovered without

damage if on occasion. If it is done repeatedly then it will have a negative impact on longevity.

Maintaining the battery charge at 13V or higher will maintain good battery life.

Look after your lithium battery and it will give you many years of service.

Can the battery be recovered from flat?

Yes. See Section 8.

Does the battery capacity degrade over time?

Yes, all batteries degrade slowly over time, even with no load sources connected. Storage temperature

is important to degradation. Roughly every 10

C above ambient 20

C doubles the degradation rate.

Cool ambient conditions are better as it slows down degradation rate.
