Operation Guide
①Check Battery’s Remaining Power
- The LED lights will indicate the battery’s remaining power
| Remaining Power | LED1 | LED2 | LED3 | LED4 |
|---|---|---|---|---|
| 0%~12% | Blink | Off | Off | Off |
| 13%~24% | On | Off | Off | Off |
| 25%~37% | On | Blink | Off | Off |
| 38%~49% | On | On | Off | Off |
| 50%~62% | On | On | Blink | Off |
| 63%~74% | On | On | On | Off |
| 75%~94% | On | On | On | Blink |
| 95%~100% | On | On | On | On |
Check Battery’s Lifespan
①Sleeping mode reduces self-consumption and starts when the battery is
inactive for 10 minutes after powering on. The battery can be activated again
by charging and discharging.
②When any cell voltage is lower than 3.65V, the BMS will enter a second-class
low-power consumption mode to ensure battery safety. If this ever occurs, you
must charge the battery immediately in order to avoid irreversible damage
Self-balancing Function
The self-balancing function is activated when the battery is left alone for more than 6 hours. In this mode, the voltage difference of each cell will meet the preset value.
Smart Storage Mode
The battery can be stored if the SOC LEDs show the modes below.
| Remaining Power | White LED1 | White LED2 | White LED3 | White LED4 |
|---|---|---|---|---|
| 50%~62% | On | On | Blink | Off |
| 63%~74% | On | On | On | Off |
The smart storage mode starts if the battery is left alone >6 days and/or if any cell voltages are >3.95V and the temperature is <60℃ (It’s the normal if the temperature rises during discharge). The smart storage mode stops once any cell voltages are ≤3.95V, the temperature is ≥60℃, or with any charge and discharge action. Store the battery in a battery box, and do not store the battery for a long period of time after it has been completely discharged. This is to prevent the battery from an over-discharged state, which will cause cell damage. If the battery is left alone for more than 5 days, discharge the battery to 40-70% capacity for storage
Common Failures And Troubleshooting Methods
| Warnings | Description | Solution |
|---|---|---|
| Charging Over-current | When the battery charging current exceeds the design | |
| value | Check if the charger current setting is correct. Disconnect the |
connector between the charger and the battery, and the warning should
disappear
Charging Over-current| Overcharge alarm will be triggered when the battery is
fully charged, but charging will continue| The alarm will stop when the
connector between the
charger and battery is disconnected and the battery voltage drops to
4.18V/cell
Low temperature| The battery temperature is too low for charging| When the
battery temperature rises above 15 °C, the
alarm will stop
Battery High Temperature| The battery temperature is too high for charging|
The alarm will stop when the battery is cooled below 45 °C
②Check Battery’s Lifespan
- Press and hold the button for 5 seconds when the battery is powered of
| Remaining Lifetime | LED1 | LED2 | LED3 | LED4 |
|---|---|---|---|---|
| 88%~100% | On | On | On | On |
| 75%~87% | On | On | On | Blink |
| 63%~74% | On | On | On | Off |
| 50%~62% | On | On | Blink | Off |
| 38%~49% | On | On | Off | Off |
| 25%~37% | On | Blink | Off | Off |
| 13%~24% | On | Off | Off | Off |
| Below 12% | Blink | Off | Off | Off |
③ Charging
- Charging when power is on: the battery indicator will turn off 10 minutes after the battery is fully charged.
- Charging when power is off: the battery indicator will turn off after the battery is fully charged.
| Remaining Power | LED1 | LED2 | LED3 | LED4 |
|---|---|---|---|---|
| 0%~12% | Blink | Blink | Blink | Blink |
| 13% ~ 37% | On | Blink | Blink | Blink |
| 38%~62% | On | On | Blink | Blink |

Cautions
① The battery protection board is not equipped with anti-sparking function.
If anti-sparking function is required, please use a connector with anti-spark
function;
② When using the charger to charge the battery, the balancing current shall
not be above 1A;
③ The battery does not have the overcharge or over discharge protection
function, and it is necessary to set the charge/discharge limit voltage on the
charger or the device;
④ Do not short-circuit the connector, otherwise there is a safety risk;
⑤ The discharge cables shall be soldered well with connector, otherwise the
power supply may be poor, and causing the aircraft to crash during the flight;
⑥ Do not pull on the battery cables under any circumstances.
※ Please read the following instructions carefully before use;
※ Lithium polymer batteries are active substances and it is easy to cause fire

Before using
① Before using the battery, please check the battery’s power and health status (see content No.3, Operation Guide 1)
② Please check if the battery is damaged, bulging or leaking. If any of the above, do not use it;
③ Do not let the battery contact metal and carbon fiber products to prevent short circuit;
④ Do not short or reverse the positive and negative electrode;
⑤ Do not pull the battery charge / discharge cables;
⑥ Do not assemble the battery by your own, Reassemble the old battery cell or reorganize one of the disassembled cells to another pack is dangerous (It’s easy to cause short-circuit and cause fire);
⑦ In the low temperature environment (below 5 °C), it is recommended to preheat the battery by charging or discharging the battery with small current to above 5 °C before use, 20 °C is best, do not do heavy duty operations when first starting use of a cold pack. Allow the battery to reach normal operating temperatures before hard use.
⑧ Do not over-discharge the battery (single-cell voltage should not be lower than 3.3V), over-discharge will damage the battery easily, such as puffing, etc;
⑨ Do not splash the electrolyte on your eyes or skin. If this occurs flush with water and seek medical advice immediately. -
Charging
① ONLY use a Li-Po battery type smart charger to charge
② It is recommended to charge in the temperature range of 10 °C to 45 °C;
③ When charging, only use a table or platform that is heat-resistant. It is recommended to use an explosion- proof LIPO battery bag.
④ Do not leave LiPo batteries unattended while charging -
Storage
① Do not keep battery near liquid as well as store them in a humid place;
② Do not place the battery near heat sources such as open flames or heaters;
③ Please Keep the battery out of the reach of children;
④ Store the battery in a temperature controlled environment of approximately 25°C;
⑤ Make sure that the battery has enough storage space (do not stack batteries in storage)
⑥ If the battery is not used for a long time, it is recommended to do a charge cycle. Charge and discharge the battery to storage level(3.6-3.9v for single cell ) every 3 months. This will ensure the best service life of the Battery.
