It is imperative to understand, achieving good performance and lowering, the risk of pack swelling, packs should always be “run” at moderate temperatures between 70-90 degrees F. Lower temps ( less than 70 degrees F ) inhibits performance because it raises the internal resistance, and higher temps (above 90 degrees F) increases the risk of cells swelling. When running the packs in extreme weather conditions, you should always keep the packs in this temperature range right up until and then immediately after use.
Immediately after use, you must put the pack back to “storage level” by charging or discharging the pack as needed to obtain a storage level of 3.8 volts per cell. Some chargers have this feature built in and it will automatically put the pack at the proper voltage level*
Make sure your speed control’s Lipo cutoff voltage set to at least 3.4 volts per cell. DO NOT ASSUME THE SPEED CONTROLS
FACTORY SETTING IS CORRECT! Only use these packs with speed controls that have adjustable Lipo-cutoff circuitry!
Always use a charger designed specifically for Regular Lithium Polymer (Li-Po) cells and/or (Li-HV) for high voltage cells. Always balance charge for longest pack life.
You need to perform a temperature check* of the pack immediately before, and then again right after use to make sure the “temperature rise” is within the safe limits of the pack. You can do this with a temp meter.
Always check the polarity of plug-in packs! Plugging a pack in backward will destroy your speed control and damage the pack!
Always check the cell count of your charger before starting it. Charging a 2S pack on a 3S or 4S setting will cause a fire!
Always keep the plugs and tubes of “plug-in” packs tight and clean. A poor connection will cause excessive heat and could melt the plastic case!
Always charge and store your lipo packs in a fire resistant lipo bag
Don’t ever allow the pack to remain fully charged for any longer than you have to! This is extremely important during warm weather!
Don’t ever allow the pack to discharge below 3.0 volts per cell. This will damage the cells. If you do find out that this has happened to you, as soon as you can, charge the pack in ni-mh mode for 5-10 minutes at 1C. Once the voltage climbs above (3.5 volts per cell) 7.0 volts (2s pack) switch the charger back to li-po mode and charge back to storage level. Check the pack again in a few days. If the voltage of any cell drops significantly you should discard the pack as it has been permanently damaged. If the voltage in the pack does not climb using ni-mh mode, the pack is permanently damaged.
Don’t set the charge termination voltage higher than 4.2 volts (STD) or 4.35 volts (HV) per cell.
Don’t use the pack if it swells excessively, the case separates, or the case is physically damaged.
Don’t pull on, twist, or excessively bend, the balance wires on hardwired packs. The wires can break off inside the case rendering the pack useless.
Don’t expose this pack to direct sunlight. The black case absorbs heat! This is especially important in summer!
Don’t exceed the recommended charge limit of 2C -100c and 3C +100c rated packs. We recommend a 1C charge rate for maximum pack life.
Don’t leave this pack unattended while charging! Unplug pack from speed control immediately after use to avoid forgetting and ultimately over-discharging the pack!
