Battery Motherboard
Battery motherboard consists of a mainboard and a power board.
Mainboard
The mainboard is physically attached to the power board. It is placed inside the battery head, used for collecting battery information, outputting, and controlling battery status. The mainboard has added nano coating technology to increase its waterproof performance and encryption authentication technology for safety concerns. After replacing the battery cell or mainboard, it is necessary to activate the power software system before use.
Battery mainboard
On the top of the mainboard, there are 4 plugs from left to right in sequence. The functions of each plug will be shown as below:
- Red 8 pin terminal – cell voltage detection for battery cell 6~13
- Black 8 pin terminal – cell voltage detection of battery cell 1~5
- Yellow 8 pin terminal – NTC(Negative Temperature Coefficient. Temperature detection and encrypted communication between battery cell and BMS
- White 8 pin terminal – communication line between BMS and UAV’s flight control
Power board
The power board is used for computation, the indication display, logic output (I/O), etc.
The highlighted area in the above picture are the major components of the power board.
1. Power button
2. Status indicator (normally solid red)
3. battery indicator
4. MOSFET control circuit. In general,MCU controls PWM waveform, and controls switching state of MOS via gate driver.
5. MOSEFT, control output on/off
6. Current sampling circuit (output current is sampled from both ends of the resistor). The sampling resistance is a resistance with a very small value, generally less than 1 ohm. There will be voltage when there is current flowing through it. The voltage at both ends is converted into voltage by an operational
amplifier. After the voltage is amplified, ADC is used for sampling and then connected to MCU. MCU knows how much the current is.
7. One flat plate fuse is added to the battery power board. The specification: 175A/57V is connected in series at the negative end of the battery output.

Troubleshooting and Maintenance
Case Analysis
Troubleshooting 1. The power button does not respond
Troubleshooting method: if the battery does not start, the indicator light does not light up by pressing the start button. If the indicator light lights up normally by pressing the start button, the battery will not enter the start state or the battery will automatically shut down immediately after entering the start state.
1. All indicators do not light up when pressing the start button
- Use a multimeter to measure whether the total voltage of the battery cell is above 38V, and judge whether cells problem causes the fault. If it is not the cell’s fault, then need to replace the mainboard.
- If the fuse is in poor condition, adjust the multimeter to the buzzer gear, connect the probe to the metal parts at both ends of the fuse, and the buzzer of the multimeter will ring. If the number is 0, it means it is normal; otherwise, it is in poor condition.
- When the connecting wire of the battery cell is disconnected, use the buzzer gear of the multimeter to test whether the power on key is normal (under normal circumstances, press the power button, use the multimeter to measure the value of two pin groups on the same side, which shall be close to 0 Ohm, or measure the resistance of SW and Vin test points, which shall be 0 Ohm, otherwise the power button is abnormal); At the same time, check whether the mainboard is corroded or burned by liquid.
- Check whether the mainboard power supply is normal (press the power-on key on the mainboard and use a multimeter to measure whether there is 3.3V voltage between 3V3 output by the mainboard power circuit and GND test point, otherwise the mainboard is abnormal);
2. Press the power on button, the indicator light is normally on, the battery does not enter the power- up state or the battery automatically shuts down immediately after entering the power-up state
- If the indicator light turns on after pressing the power on button, it indicates that the mainboard supplies power and the power on circuit is basically normal. Check whether the battery has load and whether the load communicates with the battery mainboard normally.
- Check whether the metal contact of the charging plug is aged and corroded by the liquid inlet, resulting in abnormal communication between the load and the battery mainboard. Replace battery plug for detection.
- Check whether there is an open circuit and loose contact between battery plug and connecting wire of mainboard.
- If the mainboard circuit is abnormal, the cross-testing method can be used to detect the mainboard.
Troubleshooting 2. Two battery level lights are flashing and the power light(red) double flashing
Troubleshooting methods: The battery locking state is usually caused by abnormal use of the battery. The battery failure causes the battery protection locking. Use the battery tool to unlock. If unable to unlock the battery, analyze the following specific reasons:
- Connect the battery to the computer and use the battery tool software to check the battery information for abnormalities such as large pressure difference, large temperature difference and low cell voltage.
- Use the battery tool software to check the battery information data. If there are obvious abnormalities, replace the main board kit and battery cell respectively with the replacement method to judge the fault point (first, check whether the main board kit and battery cell have external deformation, liquid corrosion, component falling off and other poor appearance)
- If there are no obvious abnormalities in the battery data shown by the battery tool software, it is necessary to use the high-power electronic load instrument to test whether the battery is abnormal.
Troubleshooting 3. The battery light is running
Troubleshooting methods: Battery upgrade failed

Troubleshooting methods: The battery lock is generally locked when the power is too low and can only be used after unlocking.
- Contact XAG technicians to unlock it;
- Use the battery tool to unlock it with the computer
- The battery is locked due to poor battery cell or defected motherboard. At this time, it cannot be unlocked successfully
Troubleshooting6. Power on after the battery is plugged in
Troubleshooting methods: There is output voltage when the battery is plugged into the drone, it is normally the MOS tube of the power board breaks down to form a path. If the mainboard circuit control fails, check whether the power board MOS tube is burned, and determine the cause of the fault through appearance.
- Use a multimeter to measure whether the resistance values of P13 and P32 are normal. If the resistance value is 0, it indicates that the MOS tube of this path is faulty (or replace the mainboard for detection)
- Use a multimeter to measure whether the resistance values of P13 and P10 are normal. If the resistance value is 0, it indicates that the MOS tube of this path is faulty (or replace the mainboard for detection)
3. Measure the CHG and DSG test points on the mainboard without power-on. There should be no voltage. If there is voltage, the mainboard is faulty (or replace the mainboard for detection);

Storage
This storage guide can apply to the products, including B13960S smart battery, XRTK4 portable station battery bar, ACS2 remote controller battery, UPS backup battery.
Lithium-ion battery are fire hazards, so How should we store the lithium batteries?
In general, Lithium-ion batteries (Li-ion) should not be stored for longer periods of time, either uncharged or fully charged. The best storage method, as determined by extensive experimentation, is to store them at a low temperature, not below 0°C, at 40% to 50% capacity. Storage at 5°C to 15°C is optimal. Since lithium batteries self-discharge, it is recommended that they must be recharged every 12 months.
We can further divide it into short-term storage and long-term storage.
Short-terms storage: Store the battery in a dry place with no corresive gases and a wet temperature between 10℃-30℃, higher or lower temperature will cause metal parts of the battery to rust or the battery to leak.
Long-term storage: As long term storage will cause the battery activity passivation and accelerate the self- discharge rate, the ambient temperature should preferably be between 10 ℃-30 ℃, in addition, it is necessary to do a charge/discharge cycle every 3 months to maintain its activity and recovery performance.
For safety concerns, please do not charge the battery full but maximum 80%. Charge 60% to 70% of the battery charge and place in a dry environment. Cooler temperatures and less charge are conducive to maintaining the life of the battery, but too little charge cannot be, because the battery will be self-discharge in storage, once the battery slowly run out of power, it will seriously shorten the battery life.
Some may ask, should the battery be removed from the device when not in use for a long period of time?
Yes. There is also a small current flowing through the shutdown device, causing a complete discharge, which can damage the battery over time, and in the worst case scenario, destroy the device along with it.
To help you understand better about the storage of lithium batteries, we’ve summarized a list of prohibitions.
- Do not charge the battery under fire or extreme heat. Do not use or store the battery near a heat source (such as a fire or heater). If the battery leaks or emits a peculiar smell, immediately move it away from the open flame.
- When the battery swells up, leaks, etc., stop using it immediately
- Do not put the battery in water or get it wet
- Do not throw the battery into the fire or heat the battery
- Do not connect the battery directly to a wall socket or car cigarette lighter socket
- Do not short-circuit the positive and negative poles of the battery with wires or other metal objects. It is forbidden to transport or store the battery with necklaces, hairpins or other metal objects.
- Do not knock, acupuncture, step on, modify, or expose the battery to the sun, and do not place the battery in a microwave or high-voltage environment.
- Do not hit, throw, or subject the battery to mechanical shock
- Use a regular matching lithium battery charger to charge the battery, do not use inferior or other types of battery chargers to charge the lithium battery.
- Do not disassemble the battery in any way
- Do not mix the battery with metal objects, lest the metal objects touch the positive and negative electrodes of the battery, causing a short circuit, damaging the battery or even causing danger.
- Do not use with primary batteries (such as dry batteries) or batteries with different capacities, models, and varieties.
- Do not use the battery if it emits peculiar smell, heat, deformation, discoloration or any other abnormal phenomenon. If the battery is in use or charging, it should be removed from the electrical appliance or the charger immediately and stop using it.
- In the transportation process, pay attention to moisture-proof, moisture-proof, avoid squeezing, collision, etc., to avoid battery damage.
- Do not use or place the battery under high temperature (in the hot sun or in a very hot car), otherwise it may cause the battery to overheat, catch fire or function failure, and shorten its life.
- Do not store in places with strong static electricity and strong magnetic fields, otherwise it is easy to damage the battery safety protection device and bring insecurity.
- If the battery emits peculiar smell, heat, discoloration, deformation, or any abnormality during use, storage, or charging, immediately remove the battery from the device or charger and stop using it.
- Discarded batteries should be covered with insulating paper to prevent fire and explosion.
Lithium battery Storage Checklist
Before storing, remove the battery from the device
