Description

Note:

This can not be used in lithium iron phosphate battery protection board, hernia lamp, hand electric drill battery, cannot be used for electric fish electromechanical ChiZu, electric bicycle batteries, car batteries, children (4 a) more than 775 motor, fisheye 1 w LED lamp, used for the combined purchase customers please note!.

The described power range is applicable to the following products:

Massager battery pack, LED light backup power supply, 12V electronics, solar street lamp battery pack, monitoring backup power, and other products.

Note: the discharge rate of battery discharge is above 3C.

Multiplier calculation formula: 1C battery, 2000 capacity is equal to 2AH * 1 = 2A working current.

3C battery, 2000 capacity is equal to 2AH * 3 = 6A working current.

In the use of the battery heating is the battery power is not applicable, this situation cannot be used for a long time, the battery will be damaged quickly.

Note 1: strictly press the diagram of 0V (B -), 3.7 V (B1), 7.4 V (B2), 11.1 V (B +), do not intentionally short circuit!

Note 2: after you connect the line, you need to charge it before you have the output.

Note 3: in series 3 battery, please ensure that the voltage of each battery is the same. If it is different, please fill it separately with each battery.In the discharge test, the group with the fastest voltage drop is the difference battery.

Explanation: don't mix good batteries with bad batteries!3 battery capacity/internal resistance is as close as possible!(2 good battery + 1 difference battery use effect = 3 difference battery use effect).

Properties of the lithium battery protection board:

Model: hx-3s - fl25a-a overcharge pressure range: 4.25-4.35 v plus or minus 0.05 v

Size: 56 * 45 * 4.0 mm overshoot voltage range: 2.3-3.0 v plus or minus 0.05 v

Maximum working current: 0-15 - a work (note that cooling temperature: - 40 - + 50 ℃

Maximum instantaneous current: 20 to 25 a storage conditions: - 40 - + 80 ℃

Static current: less than 30uA life: > 30,000 hours

Resistance: less than 100 m Ω short circuit protection, can protect, delay the recovery.

Equilibrium current: 45 mah

Charging voltage: 12.6v - 13V

Test point description: S1 S2 short circuit P + P - will output voltage, indicating that all MOS protection is normal, adding a constant temperature detection can extend the temperature protection function.

The protection board size and device description;

The protection plate size is 56 * 45 * 4.0 mm P + is the input and output positive, P - is the input and output negative
