Re: Lipo batteries for short course truck

First off make sure the ESC is good to go on 3s lipo. If so then are you running stock brushed or is it brushless system? If it something like a traxxes vxl system then 20c is a little low but will work as long as you watch your run times and how long you hold it open for. If the battery gets hot or puffs then you need higher C rating. I run 3s 5000 anywhere from 30 to 45c all day long with no problems.... Now when it comes to lipos i have tried all these vemon.oyxe packs that cost out the butt and had nothing but problems with them blowing up catching fire puffing ect and when you call them about this problem they tell you we don't ship lipo's to Canada yet i bot them here in Canada at LHS. So what i do now is go on this great site called Hobbyking and i buy turnigy roar approved 3s 5000 45/70c or higher pack cost half as much and never had any problems with them and look at it this way you can get 2x 3s 5000 hardcase packs shipped to my door that are way better way more power for the same price as 1 of there so called good name brand lipos soooo in the end even if you do pop a Hobbyking lipo your only out $30/$40 bucks and not $140 bucks they charge here at LHS hope this helped.

Re: Lipo batteries for short course truck

In addition to makin sure your ESC can handle the higher voltage, you also gotta know how much KV your motor is. That is # RPM per volts.
If you go from a 2S to a 3S, you are deliviring that much more voltage (and RPM) to the motor.

So if you up the voltage, your motor runs faster. The downside is you have a big jump from stopped throttle to full throttle, making it hard to be precise in the speed (Throttle) control

In some cases, you may have to replace the motor with a lower KV if you up the voltage.

Just sayin'

Re: Lipo batteries for short course truck

The resultant higher rpm due to upping voltage does little good if you can't lay down the extra power. The limiting factor is usually running surface conditions (traction).

Re: Lipo batteries for short course truck

Do any tracks have classes that allow 3s, or are you just bashing for fun?
