How do you store Lipo batteries when not in use for a long time? I had one stored at almost full charge and it ballooned up after 3-4 months not being used.

I received a Mamba Max ESC and motor combo from a trade (first generation-discontinued). The guy was using it on a 1/10 scale stadium truck. To demonstrate he ran the truck with a 6-cell nimhs at 7.2 volts, and then with 2-6cell packs, running at 14.v volts. Everything was OK.

Now that I transferred the ESC and motor to my truck, the brakes are very weak. How do you adjust the brakes?
I have downloaded the software. Do you still need to power the ESC and connect it to the PC via USB?

I am also using an 11.1 volts 20c Lipo 2200 mah that I think was originally for planes or Helis, Is this OK to use for a 1/10 stadium truck?


Thanks in advance!

Not sure about the esc but when storing lipo's they should be between 3.6 and 3.8 volts.

EDIT- that's per cell lol

I have two castle ESCs and a USB programmer that I've used several times, but I can't remember if you need to power the ESC independently otr if it gets enough from the USB. I think you need to power it, but don't quote me on that.

As for the lipo, it's not ideal to be honest, but it'll be ok to start with. 20C * 2200mAh=44A...that will be enough, but I don't think your battery is going to like the startup draw much, and 2200 will give you pretty short runtimes, 10 mins max in a rear wheel drive 1/10th I would think. 4000mAh at 25C is usually the minimum you'll see for surface use.

Storage is as described by the previous poster. Most lipo chargers have a 'storage mode' option. If not, around 3.7v is where they should be at.

nah you dont need to plug it into the battery the usb will power the ESC alone atleast it does with my sidewinder

Well, I finally found out the hard way.
I finally got a chance to drive the brushless GT conversion using 11.1 volts lipo.
The car was crazy fast, as soon as a noticed the car slowed down, I checked the battery and it ballooned up and is leaking some liquid(acid).

So I thought it may just be a bad battery, so I did it one more time with a different battery, and same thing. I guess I must stick with the 7.4 lipo hard case batteries.

Hm...shame, but nevermind, get yourself some batteries that can handle at least 150A (mAh*C rating= >150,000) and it'll be fine.
