I have had R/C cars before, but have been out of action with them for a bunch of years. I had a nitro Thunder Tiger Mirage buggy for a while, and before that I just had cheaper cars that ran on NiMH batteries with very simple chargers.
I just bought a Summit, 1 pair of Traxxas #2843 25C 7.4v 5800mAh batteries, and a HiTec #44167 X4 AC Plus charger with some extra leads to charge multiple batteries.
I am learning all about LiPo batteries. I've learned about what causes them to burn or explode, what causes them to degrade quickly, the storage voltage thing, etc. I think I have a good handle on that.
However, I am confused about what I think is a key points, and was hoping for a bit of clarification:
The battery says 7.4v on it. But, the charger says it is going to charge it up to 8.4v. How can it be a 7.4v battery, and be charged to 8.4v? Once charged, my multi-meter confirmed it. This does not make sense to me.
Similarly, I put the charger in Storage mode, and it says it is going to bring the battery to 7.6v, which is supposedly 50% charged. This does not make sense to me either.
Will someone please explain to me why 8.4 = 100% charge and 7.6v = 50% charge on a 7.4v battery?
Thank you for your time.
