More fun with Renogy MPPT and LFP
Toying with a new to me 12V compressor car fridge. Cheap Chinese box, LG compressor, 50L volume split ~28L fridge, 22L freezer. The goal was to see whether my added insulation made any difference: Ref...

As per my previous, while it may be in the best interest of LFP longevity to routinely cycle the battery’s charge envelope to somewhere between say 10-90% SOC (thereby deferring a periodic full 100% SOC recharge - though, cell re-balancing as well), but the potential for ‘cumulated’ meter drift needs to be considered, as well as the possibility of ongoing cell-imbalance…Conversely, a constant ON charge (whether a ‘constant on’ dc-to-dc charger or solar…) strategy might well alleviate cumulative drift, but likely at the sacrifice of a few charging cycles…However, depending on camping style (and one’s age - lol!), this small reduction in battery life (a relatively very long span) may never be appreciably realized, thus a fair enough proposition…A good compromise might simply be to allow a periodic recharge to a full 100% SOC…Just saying…
