Hey all. I'm wanting to switch my rc car to LiPo. How do I keep the batteries from running too low? Is there something I need to connect to monitor the battery or something? Don't want to drain it down too low. My best guess was to get a cheap cell voltage guage and attach it to the car so I can keep tabs on the voltage. Any better ideas?

No, thats my problem. If i was running brushless, the esc would already have these safetys in it! lol

What about running it for a pre-determined amount of time and then increasing the time until you get to the magic 80%? That is how I arrived at the 6 minutes I can fly my really old TRex 450. Why would a car be any different?

When i first started helis i took a 1800mah lipo from my dads blade 400 and put it in my traxxas rustler vxl i had. That think ran 70mph like it said it could on the box. i got to much air under the car and flipped it. it was awsome. but it works. if i still had that car i would lower the front end were it would not come up as easy.

Try a SpartanRC Lipo Guard. It's light, tough and you can program them to pretty much any cell count, type and minimum voltage warning. The LED on the unit is so bright you can't miss it, even on a sunny day!

there is a LOW VOLTAGE CUTOFF that beeps when the volts get low, check web sites that have rc cars and you should get your info to.
