How to Calculate Work Hours on a Battery.
On the high end 100 amps X 12V 1200 Watts for one hour.
Lets assume its a 12V lithium battery. That means that our 100 amp battery can sustain about 1200-vatoj from devices for an hour or 600 watts worth of devices for two hours. Watts PF amps volts. Sadly this gives me 100ah at 48v instead of 400ah due to my misunderstanding.
