It’s mostly needed for the high voltage batteries (>4S) that are more common with planes and helis. Usually for smaller lipos the amperage limit is hit first before the power limit.
I am mainly charging 4s batteries for my 1/8 Losi late model
I only have 3 batteries and was wanting to be sure I would be able charge between open laps,heat and main races.
These batteries are ran down to cutoff in about 5 minutes.
45 minute to 1hr charge times aren't always possible.This is why I want to be able to charge at higher amperage when needed.
