1/16 Scale Traxxas Slash What you NEED to know about the Battery BEFORE you buy the RC. Installation 

Much thanks!

Parallel gives you longer run time, series multiplies the voltage.

if you run series you need the brushless motor

Great question!! NO you can't use the stock NiMH charger on a LIPO battery. Here's the official statement by Traxxas: "NEVER charge a LiPo battery using a NiMH charger (or NiMH charging mode on a combination NiMH/LiPo battery charger). LiPo batteries can be damaged by over-discharging, which is why the electronic speed control on all Traxxas models has built-in Low-Voltage Detection to alert you when LiPo batteries have reached their minimum voltage (discharge) threshold. LiPo batteries should be stored partially charged, and require a LiPo-specific charger."

What kind of car and what kind of battery?

It's difficult to say what the problem could be. If the motor turns on but the controller is not functioning, it could be that the controller is not synced to the car. We have a video on this. If the battery itself is not charging, I'd call the company's support number. There are a number of things that could be causing the problem.

@@funwithrcdudes5928 I got it to work I just had to buy a new battery the stock battery that traxxas sent me was bad thanks for the reply tho.

Yeah, that's way too much battery for the 1/16 scale.
