You would have to have it set up so that you are not going to produce over voltage or current to the pack. you would need to have a voltage and current limiting circuit that you could set for the max voltage and current for the pack. It is far safer to get the right type of charger especially if you do not have an electrical or electronic background. I just bough a charger that auto detects the battery and does everything on its own myself and it was roughly around 100 bucks it is a triton if I recall, because I have all different types of pack for glow gas and electric planes.
