Li is unforgiving. Abuse it just once and you have an expensive dud on your hands. Keeping them warm at -30 would be problematic for storage. Does anyone know the self discharge rate for the LiFe format?
This is for my elite power solution gbs lithium not sure if all are the same.
How should LFMP Li-ion Batteries be stored ?
Our batteries have characteristics of very low self-leakage rate, ~ 3% per month (NOTE: Recent battery tests have shown that a partially charged battery may loose less than 5% per year), which allows batteries to be stored over extended period of time. Batteries are to be charged to 40-60% full and disconnect all loads before long term storage. Batteries should be stored in cool temperature environment. You should check cell voltages periodically, e.g. every month, to ensure proper voltage level. If any cell voltage drops to 3.0V or under, battery needs to be recharged.
If sense boards are left installed during storage the green led will cause a slight drain which roughly doubles the self-discharge rate which will necessitate checking cell voltages more often. A simple way to disconnect the sense boards is to remove the two screws from one side of the sense board and slide a piece of plastic or other non-conductive material between the battery terminal and sense board to disconnect it from the battery
