My LHS only has this one small enough for my car:
Does anyone know if an on board battery indicator rated at 4.8v is safe to use for 5 cell nimh packs? Cos on the back it says "Do not use a higher voltage than 4.8v"
If we were to put a resistor to lower the voltage from 6v to 4.8v to the indicator itself, would it still function properly? I mean would it still moniter the battery's useable voltage? ie. red colour would still mean in danger of dying out or red would still mean it still has much useable voltage?
