Hi - I have at my disposal 45 or so LiFePO4 batteries (Valence U27-12XP), which are part of my brother's estate. He also left some solar panels of different types, and a load of cables and so on, also 3 or 4 ultra capacitors. Some of this may be of interest to people here, and I am happy to sell them, but more importantly I do not know much about any of this, how to test, charge or dispose safely of such things, and am looking for advice and help in understanding what exactly I've got on my hands.
These look a lot like the pics I've seen of earlier Valence Tech stuff, but also some later ones as well. I've too many to show them all, and I've got a couple of weeks to organise a solution for them... Testing with a multimeter shows most are holding over 12v, but some are far lower. I am attempting to charge them if they are below 12v using a charger with a Lithium profile, but it only gets to about 12v or just over. Many are flashing green, some are flashing red, one or two are not flashing at all.
They are in the Yeovil area, Somerset, and I'd really appreciate some guidance (visits welcome) from you experts! In the mean time, I'm reading, reading, and re-reading again...
