We use a 2 Cell 7.4 V Turnigy LiPo Battery to power the RC car.
Be careful with the battery. For your safety:
- Never leave the battery charging while unattended.
- Never let the voltage drop below 6.0V
- Never charge the battery to over 8.4V (the charger should automatically stop charging at 8.4 V).
- Never charge the battery at higher than 5.0Amps
- When the car is not in use, don’t leave the battery connected to the ESC or the buck converter.
- If the battery starts smoking or gets on fire, treat it as a chemical fire
The video below provides a basic overview of how to charge the battery.
When charging, note the following
- Use the three-pin balance port
- Use aligator clips to clip onto the battery terminals
- Set up the charging mode settings as 2S, 7.4V, 5.0A. (note, 2S means 2 cell)
We recommend using a battery cell checker to monitor the voltage of the battery. Letting it drain too low could permanently damage the battery. These checkers have a simple display to show the current voltage, and an alarm to sound when the voltage is too low. There are many vendors that sell these checkers, here is one that we use.
