So, since getting into this, I’ve probably ruined at least 2 or 3 lipo packs. Some had dead cells and some have died through neglect. I was wondering if any of you guys with more experience could give me some advice on how to properly take care of these.
Things I know:
- Take C ratings with a grain of salt and only use half of what the battery is rated for
- Don’t charge over 4.2V
- Don’t discharge under 3.0V
- Discharge to 3.7V for storage
If I do happen to over discharge a cell, what’s the lowest “salvageable” voltage I should look for? Also, I’ve heard that internal resistance plays a large role in the health of a cell. How do I measure this and what kind of numbers should I be happy or concerned with? Thanks.
