The main function
1. Charge equalization, so that when the battery pack is charged, all battery voltages are the same to avoid overvoltage and water loss of backward batteries.
2. The discharge is balanced, so that when the battery pack is discharged, the voltage of all batteries is the same to avoid undervoltage vulcanization of backward batteries.
3. Thermal runaway warning, indicating that water should be added when the battery is thermally runaway.
other functions
1. Mixed use of new and old batteries, there is no need to replace the entire set of batteries.
2. Expand the battery capacity and extend the mileage.
3. Obtain 12V voltage directly from the 48 battery pack (24, 36V, etc. can also be obtained, and the conditions need to be in the discharge state).
4. Charge the 48V battery pack directly with 12V, 24V, 36V, 48V chargers. (Need to change the charging port wiring)

1. 48V20A balanced charge and discharge test summary (conventional use):
1. The balance charging ensures that the voltage of the original unbalanced battery is consistent, and avoids further damage such as water loss and heat generation due to overcharge of the backward battery.
2. Balanced discharge ensures that the original unbalanced battery voltage is consistent, and avoids further damages such as over-discharge of backward batteries and vulcanization and reverse polarity.
Although the battery pack is strictly matched, there will be differences in the end. Equalization makes the battery work under normal conditions, the capacity of the unbalanced battery pack is the sum of all batteries, and the life of the unbalanced battery will be equivalent to that of a single battery.

2. Product features:
1. Backward compatibility: 48V is compatible with 36V and 24V. Connect 48V and 36V in the first press. . . , Finally, the 0V requirement is connected. After the wire is connected, the device self-checks. The number of times the indicator flashes slowly per second is the number of batteries.
2. State mechanism detection and control to avoid battery black holes from consuming power. That is, it detects the state of the electric vehicle, and performs equalization protection when riding or charging, otherwise it is in a low-power standby state. After the self-inspection is completed, the device will flash intermittently in 4S units to indicate the standby state, and the steady light indicates the working state.
3. Multiple protection mechanisms: over-voltage, over-current, over-temperature, under-voltage, overtime and other abnormal state detection and protection to ensure product safety.
4. Professional aluminum profile shell: special aluminum profile shell, surface oxidation process improves the product image, and provides sufficient protection and power dissipation for the product.
Three, explain the various states of the indicator light when it is working
1. There are two main stages in the boot detection process,
1. It is the battery quantity detection stage, the indicator light flashes every two seconds, and the number of flashes is the battery quantity.
2. When the indicator light is on for 5S, it is equalizer mode self-test,
2. Standby state: the indicator light stops for 4S and flashes for 1S
3. Working status: the indicator light is always on,
4. Definition of equalizer working status:
1. The vehicle is running, and the battery pressure difference reaches 200mV, and the start is balanced
2. Ordinary type, if the voltage of any battery reaches and exceeds 13.6V, start equalization,
The voltage of all batteries drops to 13.4V, and the equalization stops
3. The anti-drum type, dedicated charging terminal is connected to the charger that meets the requirements, and the equalization is started,
4. The anti-drum type supports the normal charging start mode at the same time.
5. The anti-drum type is only for 48V 4 batteries. When the number of connected batteries is 4, it will not support the anti-charging access start, and it will be converted to a normal type.
5. Main functions and technical indicators:
1. Balance battery, constant current 10A
2. Temperature protection, 70 degrees Celsius
3. Overcurrent protection 12A
4. Overvoltage protection, any battery voltage exceeds 15.8V
5. Under-voltage protection, all battery voltages are lower than 9V
6. Thermal runaway protection
Note: The protection here generally refers to turning off the equalizer. When the equalizer enters the protection state, the indicator light flashes once every second, a total of 10 times, exits the protection state, and enters
Into the normal state. However, when a thermal runaway is detected, you must wait for the voltage of all batteries to fall below 13.4V, stop flashing for a second, and exit the thermal runaway protection.
Four, product installation instructions!
The product must be protected against short circuit before installation (as shown in the figure above). It can be wrapped with either electrically insulating tape or transparent glue to prevent accidental two wires from touching one piece and burning the fuse during wiring. !
