I am considering a small 12v 100AH LiFePO4 system for use in a camper.
In the past I had a popup camper with Two 125AH Lifeline AGM Battery. Used a RedArc DC-DC with solar controller battery charger, Bogart TM1025 Monitor, two 130W 17v photo cells, an IOTA dc converter with three stage battery charging voltage controller (good for AGM Battery charging from shore power). I liked this setup. Usually never discharged bellow 90% nightly and recharged to about 97% during the next day using solar. Ran the heater Fan, CPAP, 12v refrigerator, lights, fans and sometimes a bed warmer blanket for 15 minutes.
I will use the RedArc BCDC 1240D battery/battery charger with solar controller in the new lithium Ion Battery setup.
I will use two Grape Solar 180w monocrystal panels Vmpp 19.67vdc, Voc 24.6vdc.
I am struggling with choosing a monitor. I do NOT need one that is made for lead acid batteries. The LiFePO4 battery does not have all the problems of a lead acid battery when charging or discharging. I do not need to put back in 110% of the Discharged AH to get the battery up to 100% charge.
Any help in choosing a Battery Monitor would be greatly appreciated.
Also struggling with a shore power charger choice. Looks to be a pretty simple charging routine for LiFePO4 . Start charging when Battery gets to 10.5V min, charge at 14.2-14.5 V until battery is 100% charged. No Need for absorb or float charge. Do not exceed 14.6 volts charging. Never Equalize the LiFePO4 battery.
Have not found a simple charger that works as described above. 40-60A charger would be preferred.
Any help choosing a battery charger would also be appreciated.
