Hi folks.
There's a new charger on its way from Hitec, the X4 80, it's a DC only charger with 80 watts max per channel, and it can simultaneously and independently balance charge 4 packs at a time. I'm wondering though, at 80 watts max charge rate per pack, what does that translate to in terms of max charge C ratings for a typical 4S 5000 mah pack?
Maybe I can figure this out a little;
a watt is a volt-amp and we're charging 3.7 volt cells so each cell is getting maybe 4.5 volts to charge it? so 80 watts divided by 4 cells in a pack is 20 watts available per cell. so if each cell has 20 watts available and it's coming in at 4.5 volts, then each cell (C rating) can be charged at about 4.4 amps max?
is that right?
it's amazing what a brain can do after a little caffeine.
