Maintenance & testing questions
Short answers to the ones that come up most.
How do I test a battery?
Resting voltage, then voltage under load, then internal resistance.
What maintenance does lithium need?
Terminals, ventilation and the BMS log — nothing else.
Is a swollen battery dangerous?
Yes — stop using it and replace it.
How should I store a pack?
About half charge, cool, disconnected.
When should I replace a battery?
When delivered capacity no longer meets the job.
