Seems to Do The Job
I'm not all that knowledgeable about lithium batteries. But everything I read, on the net (it must be true), suggests that the battery will last longer if it's left with an 80% or less charge.
The charger that came with my Rad Rover leaves the user with no information or control over the batteries charge.
The Luna charger has controls for charging AMPs and the total % of charge. The red LED gives me a view into the process.
I've dropped it on a concrete floor from a 4 foot drop. It continues to function without complaint.
I hope I'll have the same positive confidence in another year or two.
