CHARGE & POWER

~2-3 hours
//You'll need
  • The LiPo charger that shipped with your kit.
  • An 11.1 V (3S) LiPo pack. See "Battery specs" below.
  • An AC outlet.

BATTERY SPECS

The car runs on a standard 3-cell (3S) LiPo at 11.1 V nominal. Use a capacity between 4000 and 5500 mAh, a of 25 or higher, and an XT60 connector to match the car's lead.

CHARGING THE BATTERY

01
Place the LiPo on a non-flammable surface.

A concrete floor or a LiPo charging bag is ideal.

02
Plug the AC side of the charger into the wall.

The screen turns on with a boot screen, then the main interface loads. The home screen shows the per-cell voltage (V) highlighted at the top and the current (A) options in green text on the right.

03
Set the cut-off voltage and the charging current.

Hold the button for two seconds to adjust the voltage and select 4.20 V. Press the button to adjust the current and select 2.5 A.

04
Connect the balance wire to the charger's balance port.

The balance wire is the plug with several small wires, usually one red and one black.

05
Connect the main XT60 lead.

The battery begins charging immediately.

06
Stay nearby until it reaches full.

At 2.5 A, about half a C for a 5000 mAh pack, a full charge takes roughly two and a half to three hours.

SIGNS OF A BAD BATTERY

The pack looks puffy or balloon-shaped.
A swollen pack is no longer safe to use. Disconnect it, move it somewhere fire-safe, like a bucket of sand, and replace it. Do not charge it again.
The pack can get warm, but never hot to the touch.
If you cannot comfortably hold the pack, stop charging and let it cool in a fire-safe location for 30 minutes.
Sweet chemical smell or any visible smoke.
Disconnect if you safely can, then leave the room and call your fire service if there is open flame. LiPo fires burn bright white and accelerate fast.
