Ok I have 4 T1275 batteries from my golf cart. They are rated at 12v , 150 amp hours each. I also have the 48v, 13 Amp charger. If i have the four in series for 48v, then I would only have 150 amp hours of capacity right? Right now I have a 32" flat screen tv. A DVD player, and four led lamps. Just wondering if I have enough batteries to run what I have now. If so I'll be charging from a small generator. This is all I have, as I had a house fire, and the golf cart body took major damage. If I do have enough batteries, what would be a good 48v invertor for now and later down the road "bigger system" and will I need a charge controller?
