[QUOTE="condor22, post: 630296, member: 1932"] RR Had a look at the specs - 121.621 mAh/14,8 V if my math is correct is 120AH (roughly) with an 11-12 hour charge time. that's about 0.1C In the near future, when the new van arrives I'm putting in 2 x 100 AH Pylontech lithium batteries to drive the 2 fridges etc. Their charge rate = 0.5C, 5 times faster (subjest to charger size). I am amazed how expensive things are over there as I can get 100 AH of Li oN for around 500 quid. I do realise it has a lot of other stuff hanging off it, well inside lol. Fortunately the new van's battery management system caters for Lithium, has MPPT inbuilt and allows me to add a further 320 W of solar (above the 120 panel fitted). So with a little minor rewire of the solar to add a parallel Anderson or 2 for extra panels, I don't need to buy anything else. Oops, I do, lol, Gonna fit a diesel heater and will need to fit a Shunt to power it. Fortunately the BMS has an option which will also monitor it. [/QUOTE]
