I have been given the remains of a toy R/C airplane which runs (ran) on NiMH batteries. It gets recharged in the field for a few minutes from a battery pack, then supposedly flies for a minute or so on a charge. Rinse and repeat.
It's no longer an airplane, just a pile o' parts. If I replace the rechargeable NiMH pack with standard alkalines, then don't even think about putting the charge voltage on it, are there likely to be problems?
Comments welcome and appreciated. A diode in there, perhaps, to make sure it is isolated from the charger circuit? Many thanks.
