re: Help needed: trying to connect LED light bar to generator for night fishing

Some info on the LED light bar. Not sure what is relevant.
- Current draw 16A @ 12V, 8A @ 24V
- LED Power: 120W
- Operating Voltage: 10-30V DC
How long do you think a marine battery will keep that going?
Didn't think about a trickle charger. That's a good idea.

Off of one good 115 amp hour battery, it would be 7.2 hours

Two 12v volt batteries in series will give you way more power than you need for multiple trips.
I am going to assume you know the difference between AC and DC power and why you can't just plug them up to the generator.
Take the ratings given to you, for example 8 Amps at 24v and multiply times the time needed. for example 8A x 8 hours = 64 Amp hours required from the batteries. Conversely if your batteries are capable of 240 amp hours and your draw is 8Amps you have 30 hours of power available. This will vary some depending on state of charge and battery condition but is a good rule of thumb.
