LiPo Safety

Quick Reference

LiPo Voltage

Fully Charge	4.2 V
Storage Voltage	3.8 V
Nominal	3.7 V
Low	3.5 V
Critical	3.0 V

LiPo Maximum Charging Current

$$I = capacity / h$$

e.g. for a 2200 mAh battery, maximum charging current should be 2200mAh / h = 2.2 A

General Safety

Charging

• NEVER LEAVE A CHARGING BATTERY UNATTENDED.

• Double-check the parameters on the charger. Make sure cell type, cell count, and maximum charge current match the label on the battery.

• Never charge a battery that is still warm after usage, and never use a battery that is still warm from charging.

• Never charge your LiPo batteries inside a Vehicle.

In Use

• Never expose LiPo batteries to extreme temperatures or in direct sunlight for prolonged periods. The suitable temperature range is between 4 °C ~ 49 °C (40 ~ 120°F).

• Never discharge your LiPos below 3 V under load.

• Take LiPos out from the model when you’re done.

• Put LiPos on a clear surface when not in use for a short amount of time. DO NOT put them into your pockets even for short periods.

• Keep battery connectors/terminals away from metal objects.

• If the LiPo battery is swelling (puffing), stop immediately and dispose of it.

Storage

• Always store your LiPos at room temperature of between 4 °C ~ 21 °C (40 ~ 70 °F).

• If you will not be using your LiPos for more than three days, charge/discharge them to storage voltage.

• Never store your LiPos fully charged.

• Make sure each cell is as balanced as possible.

• Check the Internal Resistance (IR) and Voltage (V) for LiPos that have been stored away for more than 6 months. For safe LiPos, the voltage of each cell should never reach below 3V and the IR should not exceed the original value by over 80-90%.

• Batteries that have lost 20% of their initial capacity should be removed from service and disposed of properly.

Disposal

If the LiPo battery is swollen, ballooned, or damaged, or has been overcharged or over-discharged (voltage have been fallen under 3V), or has lost 20% of its initial capacity:

• Fully discharge the battery with a resistive load.

• Keep close monitor of the battery's temperature.

• Bring the battery to a proper recycle center.

Using the B6AC Style Charger

1. Click "Batt. Type / Stop" button, select the correct battery chemistry type. Click "Dec. / <" button to change type. Click "Start / Enter" to confirm selection.

2. Click "Dec. / <" or "Inc. / >" to change charging type to LiPo BALANCE. Click "Start / Enter" to configure maximum charging current and cell count. Click "Dec. / <" or "Inc. / >" to change value.

3. Plug in the battery main terminal and balance port. Long-press the "Start / Enter" button to start battery check.

4. Click the "Start / Enter" button to start charging.

5. During charging, clicking "Dec. / <" or "Inc. / >" can view different battery info.
