In any event is the Luna charger still considered a valuable asset to ebike battery maintenace?
Hi Tom,
Fellow EE here.
Here's the basics of what you need to know re. Li-Ion battery maintenance:
- Try to keep it between 20-80% state of charge usually. It's fine to charge to 100% and discharge to 0% when you need to.
- Do long term storage (> 2 weeks not ridden) at around 50% state of charge
- Use your charger with a outlet timer, along with some basic calculations to do this ↑. You don't need a fancy charger. For example, if your battery is 10 Ah and you ran it down to about 20%, it needs 6 Ah put back into it. If your charger charges at 2 A, that's 3 hours on the charger. I find it usually takes less than calculated, as the battery gauges aren't that accurate.
Doing these things will about triple the life of your battery.
