Индикатор напряжения аккумулятора индикатор состояния Подходит для литий-полимерных литий-ионных и свинцово-кислотных батарей с напряжением 9 в до

*Attention:

*Prevent wrong positive and negative protection, wrong connection will not burn out

*With 300 mm wires
*Lead-acid batteries & lithium/Lifepo4 batteries all can use

*We set up the delivery, hand direct use, can also set their own

Accurately display the battery power percentage and voltage, intuitively grasp the battery use state

*With its own switch, it can turn off the power, no power consumption after it is turned off

Double button design, simple and efficient Settings, only a few seconds can be set up

*Setting key post-setting: Avoid arbitrary setting by terminal customers and reduce after-sales service

*Date details:

*Setting steps
1. Disconnect the power of the power display board, hold down the setting button, release the setting button after the power is switched on, and the display screen shows the current setting parameters of the power;
2. Press the setting key to select the battery specification P/L/F(P=12V lead-acid, L=3.7V lithium battery, F=3.2V lifepo4 battery);
3. Press the function key to set the number of battery series. Press the function key and the setting key to select the number of battery series up or down;
4. Long press the function key to enter the advanced Settings interface, use the Settings key to select S1-S5, and confirm the mode of selecting or deselecting;
5. Power on after setting, the setting data will be saved automatically.
Example: 10 series of lithium battery power, turn on power percentage voltage automatic rotation display (S1 mode)
Operation: Disconnect the power display module, hold down the setting key to connect the power supply module, press the setting key to select L, press the function key to select 10, and long press the function key to select S1, and then power on again.

*Matters needing attention

1. The LCD screen of the module is made of glass, which is fragile. Severe falls, heavy loads and impacts should be avoided.
2. The liquid crystal of the module is made of HTN material with wide temperature. The operating environment is -10℃~50℃
When the temperature returns to the normal temperature, the LCD display will automatically recover.
3. The ambient temperature of liquid crystal above 50℃ will shorten the service life of liquid crystal.

Q : What is balancing function?

A :Working principle and function: when the battery voltage has a series to reach the voltage of

balance open voltage of (lithium)4.18 V /(lifepo4)3.58 V(Need according the specification), the

balance of the section on protection board will automatically open, balanced protection board after

open a well balanced resistance will with 42 mA to discharge (when the balance start the discharge,

protecting plate back there will be a slight heat, this is normal reaction) and then Charge and discharge

simultaneously, other section voltage didn't reach balance open voltage of 4.18 V / 3.58 V, is charged

only, then the highest section to overcharge protection voltage will be power-off protection, other batteries

will be stop charging.This working principle can make the battery charge in balance, so that the battery

voltage balance effect, but if the battery voltage gap is large, then the function of balance function is basically   no have.

Q : Relationship between battery capacity and current of BMS

A :There is no direct relationship between the battery capacity and the current of the BMS. That is to say, the larger   the motor, the larger the continuous current of the BMS you choose will be,

and the battery capacity is not directly related
