One important thing to remember is that you will kill a pack if it goes below 6 volts. Therefore always put at least half a charge back into your lipos after use as they continue to slowly discharge even when not in use. If you run a pack down to cutoff then dont recharge it can still drop below 6v. Another good practice is to know how long you will get out of a pack and run it a few minutes less. LVC or low voltage cutoff is a safety measure and it not a good idea to run until it kicks in as one day it may not work. Always store your lipos at 50% charge or 7.2v, in a cool environment and dont over discharge. Your lipos will last a long time that way
