Rechargeable tools / invertor / how long

[Andrew1972]

Hi I have ego rechargeable tools each with 2.5 aH batteries.

If I acquire the ego inverter that is 150w max and give it a 100W load , how long will each 2.5aH battery last?

Thanks for any ideas how to calculate.

Need voltage of those batteries to do the math.

what volts are the ego batteries if 56volts about an hour maybe 75min.
depends on how close to 100watts the load is.

Few different ways to figure this out. of course I'm not including electrical losses.
watts = volts x amps
volts =56
56x2.5ah = 140watt hour battery

Easiest way is to figure out your battery size in watt hours then add about 15% to your load for conversion losses.

Sorry 56V
