Got a question for someone smarter with electronics than I. I have an idea and want to know if it's doable or if for some reason it is not. Maybe it's been done already. Anyways, putting my pit trailer together and I bought a 300.00 HD Deepcycle battery to run the 12v stuff. What I want to do is be able to power say a tv, and maybe a light at night when the generator can't be ran. I know this can be done with an inverter but here's my question. I have a battery charger that charges the DeepCycle bat at 3 amps. It says it draws .7 amps. So I rounded that up to 1 which would be 1000 watts. The tv draws 23.7 watts and the light has 2 bulbs 40w each so another 80 watts. So less than 2000 watts total. My thought was to wire the inverter into the power box to power the lights and tv and the battery charger. So will the inverter draw more juice from the battery than the charger is replacing or would it keep a happy cycle going? Hope this makes sense.
