I have an opportunity to get some LiFePO4 batteries for our RV. But I'm not sure how many amp-hours I should get. I don't have solar panels yet, and we have so far been on shore power most of the time, but we want to change that.
For power consumption DC, we have the fridge+propane, the water pump, the interior lights (not LED yet, but will be soon), a car stereo, a mobley, a small stick PC, and we'll be adding some USB outlets direct from the breaker box to power cell phones and small electronics.
For AC we have two TVs with Apple TVs, though only one is used at a time, an ethernet switch and router, a cell signal booster, once a day use of coffee maker and microwave, sometime use of a crockpot, and charging our laptops.
We are currently in an area that is getting cold at night, so we use an electric heater, but if we are boondocking, we shouldn't be anywhere that needs that or AC.
Thats really about it. The stick PC might be replaced with a slightly larger PC, but still not a big tower. Once in awhile we'll have an Xbox 360 running, but that's not every day.
I think I can get a 300aH battery, but I'm not sure at this point. I don't know if that would be enough though, even if only discharging to 10%, it would still be 270aH. Whatever size battery we get, we'll get enough solar panels to charge it though, but this is being done a little at a time.
Any thoughts?
