Charging Batteries

The 2 Interstate SRM-24 batteries are rated at approx 82 AH each.

Since flood batteries should be charged at no more than a C/10 rate (where C/10 = battery AH / 10), then considering the batteries are connected in parallel, the ideal charge rate is no more than 82/10 X 2, or 16.4 A.

A 1000W Honda EU100i generator is rated to deliver 6.5A DC max direct but is not regulated in any way (best to use a converter/charger)

A 2000W Honda EU2000i generator is rated to deliver 8A DC max direct.

The EU1000i would be a good choice for recharging needs in conjunction with a 3 stage converter/charger, or simply plug the generator AC output into the trailer shore power receptacle, which appears to charge more in the 4 to 5 A range.

Electrical Usage

With batteries charged approx 3/4, and connecting to shore power, the batteries charged at approx 4.25 A initially then down to approx 3.2 A after approx 10 minutes. Further tests will have to be done with the generator to check into charge rates, and the necessary time to top up batteries.

 Appliance Current Required
 all off - disconnect set to OFF 0.00 A
 all off - disconnect set to ON

 0.04 A (.02A for the switch lamp, 02A for propane detector)

 radio on low 1.54 A
 fridge on without fan operating 0.31 A
 fridge on with fan operating 0.93 A
 individual lights with toggle switches 0.83 A each
 individual pot lights 0.83 A each
 system monitor on 0.06 A
 over dinette lamps 0.96 A each
 heater (fan) 3.20 A
 vinq guard tv amplifier on 0.08 A
 fantastic fan on low (speed 1) 1.00 A
 fantastic fan on medium (speed 2) 1.40 A
 fantastic fan on high (speed 3) 1.80 A
 water pump 6.4 A (up to 8.5A if water partially on)

Obviously the real loads will be the heater and radio. Best bet for the TV which requires shore power to operate, would be to use a portable battery with built in inverter to provide 120V AC for the TV.
