I really could use some help understanding where my lippos should be as far as Max and Min charge.. I understand running them too low will do damage.
Such information should be provided with the battery packs themselves, as overcharging seems to be the main cause of LiPoly fires.
For our purposes, LiPolys have a MAXIMUM voltage of 4.2 Volts per cell. You do not want the charge voltage to exceed that.
It is generally recommended that you also do not go below a MINIMUM voltage of 3.0 Volts per cell. Something on the order of 95% of the pack's capacity is in between 4.2V and 3.0V, so running it any lower doesn't really gain you much.
What does this mean for packs? To get the maximum and minimum voltages for a pack, you multiply the maximum and minimum cell voltages by the number of SERIES cells in the pack. An 11.1V pack has three cells connected in series. 3 times 4.2 Volts gives you a maximum voltage of 12.6 Volts. 3 times 3 Volts gives you a minimum of 9 Volts.
