Charging Li-Po

Article content

  • Cool the battery down to ambient temperature before charging.
  • Charge ROC Li-Po batteries with quality Lithium Polymer specified charger. A poor quality charger can expose you and your properties to premature degradation and fire danger.
  • Set voltage and current correctly (failure to do so can cause fire).
  • Do not charge a 2-cell pack below 6.6V / a 3 cell pack below 9.9V.
  • Do not charge batteries packs in series.  Charge each battery pack individually.  Failure to do so may result in incorrect battery recognition and charging functions. 
  • Do not discharge a battery to a level below 3V per cell under load. Discharging below 3V per cell can deteriorate battery performance. Be sure to set your ESC for the proper cut off voltage (6.0V cut off for 2S packs, 9.0V cut off for 3S packs, etc).
  • Avoid puncturing Li-Po battery as a damaged Li-Po battery may cause a fire.
  • Never attempt to charge at a rate faster than that recommended.  The general rule of thumb for the maximum charge rate is 1/6th of the ROC Li-Po continuous discharge rating. 
  • Never leave your battery unattended while charging or discharging.
  • Charge on a safe surface or in a fire resistant container or a charging bag specifically designed for this purpose. Charge only on nonflammable and non-conductive surfaces, e.g. concrete, Pyrex cooking dish, or clay pot.  Do not charge a Li-Po battery inside a car!
  • NORMAL CHARGING: The charge rate should not exceed 1C (unless otherwise noted).  Higher setting may cause problems which can result in fire.  For example: Charge a 730mAh battery at or below 0.73Amps. Charge a 5000mAh battery at or below 5Amps.
  • Please check pack voltage after the first charge. Example 2-Cell: 8.4V (8.30 to 8.44) 3-Cell: 12.6V (12.45 to 12.66)
  • Keep a bucket of sand or chemical extinguisher (ABC, BC or CO2) nearby.  Use the sand from a fire bucket or a fire extinguisher (ABC, BC or CO2) to douse the flames. DO NOT USE WATER!
