Internal ressistance of lead crystal batteries
« on: January 21, 2020, 05:33:35 PM »
Does anyone have the stats for the internal resistance of lead crystal batteries please?
Looking at some 120 amp hour 12 volt units ex telstra 2 years old.
I do have 8 that have been tested to be 80-90% soh.
Am going to run my battery tester on them this afternoon to hopefully get some usable data.
Standalone. 20 Hyundai x 220 watts panels, 2 x classic 150's, Latronics 24 volt 3kw inverter, Whiz bang Jnr, 12 Rolls surrete  4KS 25P  batteries and WBJ.
Grid tie feed-in, 12.5 kw in 3 arrays generating 50 kws per day average. Solar river grid tie inverters
