Got a question for you about lipos

[kgb424]

I bought a used Arrma Vortex, and it has a built in battery tray in the bottom of rc, its needs a recommended battery sized 138mm x 47mm x 25mm is this a common size, and if you get one smaller the recommended size does it move around, and damage the battery, if that is the case, would it be better to buy a hard case lipo the the recommended size to avoid damage to battery correct.

Not familiar with that setup but you can use sticky back velcro (hook and loop) to stick a battery in place. I like the hook side on the tray and the loop side on the battery.

Amoured batteries are a good idea but since crawlers are generally slow they are not really required. Lipos come in lots of different sizes which is part of their advantage.

I have a couple of amoured lipos and they are 139*47*24

so you should be able to find the size you need.
