the general rule with lipos is theres two ways to get them hot under use. draw too high of amperage or over discharging them. if warm is like 90f , your fine, just don't fly em much longer per flight if it's a overdischarge thing, if it's an over amperage draw and the batteries are rated to do it, i'd question the internal resistance of the pack which gets killed from either of the two above as well as storing them charged for more than say 2 weeks at a time depending ont he brand and age of said pack.
They don't live forever and the harder you are on the packs, the less time you'll spend flying them
One way to tell if your over discharging them is by how much maf the pack takes back in during charging, if it's a 2200mah pack and you see it taking in excess of 2000 mah per charging, your overdischarging it. you rlooking to leave 20% mah in the pack when your done. it only really works on a newer pack though cause if you damage a cell, you start holding less mah. so a battery you used to get 5 minutes flight on now really only gives 4:30 and decreasing rapidly with each over discharge. When you start to kill one, you want to get it out of rotation
