Known Causes for Battery Swelling

Known causes for battery swelling:

  • Leaving the LiPo battery plugged into the main drive unit when not in use is not recommended. The battery may continue to drain - and if the voltage drops below the minimum voltage this will permanently damage the battery. This would not be covered under warranty, so to protect your investment ALWAYS disconnect the battery plug from the drive when not in use.
  • Leaving the battery plugged into the charger after reaching a full charge
  • Unevenly charged cells- the cause of this is not allowing the battery to charge to FULL - 
    • using the B3Pro charger - all three LED must turn green or the battery is not fully charged and an imbalance in the charge between cells is almost certain.
  • Allowing the battery to get too hot - such as it would get inside a parked car
    • attempting to charge a hot battery can damage it, causing the internal cells to swell - risking fire and explosion
  • Allowing the battery to get too cold and attempting to charge it before the battery's internal temperature is allowed to reach room temperature.
  • Over charging the battery - leaving it on the charger after it has reached a full charge
  • Over discharging the battery - using the battery longer than is recommended. 
  • Storing the battery fully charged - the internal gases can build up inside
  • Storing it in a place that is either too hot or too cold

Always charge the LiPo battery inside a fire resistant container such as a fireproof battery charging bag.

IMPORTANT: charge to "FUL" every time to assure proper balance of all cells inside the battery. 

If the battery is used before it reaches FUL - this will permanently damage the battery causing it to stop taking and/or holding a charge.

CAUTION: The battery should always be allowed to come to room-temperature before charging. Charging a hot or cold battery might delay charging or damage the battery. For best results, charge the battery at temperatures between 50º and 80ºF (10º-30ºC).
