I removed the C-Tek charger and fitted 4 single cell chargers. But the 4 single cell chargers (4A) were not able to replace the normal daily power usage when switched on over night (off peak). But I thought it was ok, and just play catch up on the weekends. Obviously not. One morning not so long ago, I found that the single cell charger did not switch on, possibly because the cell voltage was too low. Well that doesn't help a cell that is already too low. It still had to supply power to the main monitoring screen, while the main pack was being charged at the same time (off peak overnight). I found it had been reversed. Dead. I tried to charge it but it would not take a charge. So I replaced it with a LYP. The original 4 are LFP. I will leave it with single cell charging, so the 2 chemistries don't muck me up if I were to charge with the C-Tek. Dad cut the dead one open. Nothing run out, but it was moist with something inside. A clear like fluid. The plates were just copper and aluminium foil alternating with some kind of insulation between them.
