having both a 50watt balancing charger and an 80watt balancing charger, i wish someone had told me to bite the bullet and invest in a higher wattage model, say 200watt and up... i bet it's cheaper in the long run
a 50watt charger is fine i think for RC, but consider how this works out for EV applications. for example, my 3s 8000mAh lipo has a max charge rate of 5C, or 40a.
that means with the 50watt B6 rated to a max of 5a, i'm recharging at a rate just around 1/2 C, realistically 4a. and running the charger at 4a for an extended amount of time, for multiple lipo packs, means this charger is getting very hot.
and there is no way i'd consider parallel charging high capacity lipo packs with such a small wattage charger either...
