How was the the reignition of Apollo 13's LEM engine possible?
Were there any risks in reigniting the engine with battery power?
Yes, there were risks. The Lunar Module was not designed to be used as a power source for the engine and there was a risk of the battery overheating and exploding. However, the engineers were able to calculate the safe amount of power to use for the engine ignition.
