I have a EE degree and am trying to learn all I can about battery maintenace. I did a search on the forum here and didn't really come up with much. Probably because I am not using the search properly.
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.
