Lithium-ion battery packs are expensive, so if you want to make yours to last longer, here are some things to keep in mind:
- Lithium ion chemistry prefers partial discharge to deep discharge, so it's best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a "memory", you do not harm the battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it's ruined.
- Avoid heat, which degrades the batteries.
