battery re charging.
A standard ni cad main battery is charged either by the aircraft system or removed to be charged in the Battery Shop.
The difference between the two processess is that on the aircraft the battery is charged at a constant voltage and varable current, while on charge after cap test the battery is charged at constant current, say 22 amps at a varable voltage.
Therefore the overheating caused by high current charging on the aircraft is avoided by the Battery Shop process.
