Rv update Working on UPS backup systems



I have been looking for UPS battery backup systems and I use them for power in the RV. I upgrade some of them to gain more power and run time on them. The have a built in charger so when they are plugged in the batterys are charging. Most can be turned on without being plugged in to the wall. Some dont work like that, They have a DC start header so I use a switch to turn it on. on a 4AH battery I can run CFL lights for several hours. With a larger battery they can run all night(apx 8-10hours). I havent seen how long they run before the UPS shuts down.
