i have lipo cutoff on all mine, and i have yet to run it down to its limits. just know what your limit is, and dont go past it.

i have 5000 packs, and run on the track for a good 10-15 minutes with a 10.5 brushless-great speeds too.

and i never activated the cutoff. so know what your battery can do, and dont push it's limits.

after 10-15, i recharge and the voltage is at 7.3 volts give or take a few tenths of a volt.

so the 5000 packs are worth the money.

makes me remember ni-cd packs when i was a kid, and using the 15 minute quick charger.

15 mins to charge, and about 2 mins of solid fast speeds, and 3 minutes of dying speeds, then the battery was dead, and hot.

anyone remember the first style deans plug??
with the 4 pins. and you had to solder the wire on 2 of the pins and the other wire on the other 2 pins, what a pain that was.

does anyone know what the other fancy battery connect was called??? it was orange, with 2 pins on the back, and the connection was like a large prong with the metal on either side. this was back in the very early 90's
