Safety Information

5) Be sure you use the shorter lead with the JST (BEC) connector for all charging. This is the lead protected by the Charge
Protection Circuitry referenced in the introduction. There are two sets of lead wires on this battery. The shortest one is always used
exclusively for charging.
6) When selecting the cell count or voltage for charging purposes, select the cell count and voltage as it appears on the
battery label. Selecting a cell count or voltage other than the one printed on the label can cause fire. As a safety precaution, please
confirm the information printed on the battery is correct.
a. Example: The label on a 2-Cell battery pack in series will read – “Charge as 2-Cell (7.4V), or may cause fire” – You must
select 2-Cell for charging.
b. Example: The label on a 3-Cell battery pack in series will read – “Charge as 3-Cell (11.1V), or may cause fire” – You must
select 3-Cell for charging.
7) You must check the pack voltage before charging after flight. Do not attempt to charge any pack if open voltage per cell is less
than 3.3V
Example Do not charge a 2-cell pack if below 6.6V
Do not charge a 3 cell pack if below 9.9V
8) You must select the charge rate current that does not to exceed 1C (one times the capacity of the battery, unless otherwise
noted*). A higher setting may cause fire. The below chart is calculated at 1 x capacity of pack.
Example 860 mAh: Charge at or below 860 mA
1200 mAh: Charge at or below 1.2 Amps
1800 mAh: Charge at or below 1.8 Amps
2100 mAh: Charge at or below 2.1 Amps
First Flights
We recommend 3-5C max average discharge for breaking in new packs. Also be extremely careful not to over discharge new packs (Packs
should NEVER be over discharged at any time, but over discharging on the first flight will ruin the battery permanently before you are able to
enjoy it. See “Caring for Battery” below).
Storage & Transportation
1) Store battery at room temperature between 40 and 80 degrees F for best results.
2) Do not expose battery pack to direct sunlight (heat) for extended periods.
3) When transporting or temporarily storing in a vehicle, temperature range should be greater than 20 degrees F but no more than 150
degrees F.
4) Storing battery at temperatures greater than 170 degrees F for extended periods of time (more than 2 hours) may cause
damage to battery and possible fire.
Caring for Battery
1) Charge battery with good quality Lithium Polymer charger. A poor quality charger can be dangerous (such as the MRC Super Brain
969 which is NOT a proper Lithium Polymer charger).
2) Set voltage and current correctly (failure to do so can cause fire).
3) 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)
4) Do not discharge battery to a level below 3V per cell under load. Deep discharge 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).
5) Use caution to avoid puncture of the cell. Puncture of cells may cause fire.
Operating Temperature
Charge: 32 to 113 degrees F
Discharge: 32 to 140 degrees F
1) Let battery cool down to ambient temperature before charging.
2) During discharge and handling of batteries, do not exceed 160 degrees F.
Battery Life
Batteries that lose 20% of their capacity must be removed from service and disposed of properly.
Discharge the battery to 3V/Cell, making sure output wires are insulated, then wrap battery in a bag for disposal.
