For LiFePO, a parasitic load might be protective. It's that full charge that is destructive. On Sat, Jul 24, 2021 at 11:40 PM EVDL Administrator via EV < ev@lists.evdl.org> wrote: > On 24 Jul 2021 at 21:04, Michael Ross via EV wrote: > > > The worst thing you can do to LiFPO is to charge it

My personal experience is with the LiFePOcells, but the issue is there for all/most? It's a shame because they are the most affordable (well maybe, I haven't bought any since 2015). In particular, the temperature at which trouble starts is significantly lower for LiFePO. I think if you go right

[EVDL] LiFePO4 EOL behavior

2021-07-24 Thread Christopher Darilek via EV
Hi Guys, I have an 8 year old LiFePO4 pack in my car and wonder if anyone knows what the end of life failure mode is for these? Over the pandemic lock down I was not driving the car for 3 months and noticed one day that all the cells were flat, ~2V. I attributed this to some parasitic loads
