I have had cells go as low as 2.6V under rest immediately after a long run with LVC disabled... I boosted the pack in NiMH mode for about 30 sec to get the cells above 3.0V each then I finished the charge in LiPo mode. While I didn't have an IR meter at the time, I was able to get about 2 more months of use out of the pack before it started to swell and lose capacity/performance.


There is no hard set rule on how long a pack will last after discharge/charge but heat is the #1 cause for degradation of any pack and an IR meter can be used as gauge to give you a better idea of the health of your pack.
