Detail

 

2S 2-3A

Tip: After connecting the battery protection board is locked because the internal state, no output, only need to use 12V / 1A adapter activation charge, so there is normal output.

The latest version of the improved features:

  1. The use of plastic irrigation package inductance, low voltage battery charging no high-frequency noise;
  2. The input voltage is increased to 20V, 18V solar panels can be used directly as a rechargeable power supply.
  3. Battery pad default pre-stack tin, battery welded and fixed alignment easier.

 

Product description:

This product is compatible with 9 ~ 15V 1A output current over a variety of power adapters for a variety of various shapes 3.7V18650 capacity lithium polymer batteries. IC module to protect the main chip used in Japan MITSUMI original series, the switch MOS transistor used by the US National Semiconductor 6N original series, the maximum allowed by the current 6A, DC converter system uses the US MILPITAS, professional-level power management chip, high conversion efficiency, low fever , charging current. This module uses Samsung ceramic capacitors and high-precision resistors KOA Japan, the United States VISHAY original diode plate for the military grade Tao Jian FR-4 glass fiber sheet, design, fine workmanship, a comprehensive test. Compact, suitable for a variety of demanding high-integration, high stability requirements of the occasion to meet the wide range of performance requirements, to ensure absolutely safe and reliable battery pack.

The module consists of two parts:

Function Description:

1, according to wiring diagram to connect the lithium battery with protection board, when the battery voltage between overcharge and discharge, and Vin +, GND charge for 1 second, Vout + and GND output voltage is 2S battery voltage.

2, the battery overcharge function: between Vin + and GND plus charger to charge the battery, the light turns red, the battery voltage charge to overcharge detection voltage (8.40 ± 0.025V), the charging system operation indicator green, stop charging achieve overcharge protection.

3, battery over-discharge protection: in between Vout + and GND connected load to the battery discharge when the battery voltage drops to over-discharge voltage (5.0 ± 0.08V), the protection circuit, shut off the discharge path to achieve the over-discharge protection.

4, short circuit protection function: When Vout + and GND short-circuit protection circuit will quickly action within 5-50uS, cut off access, short-circuit protection.

5, over-current protection: When the Vout + and GND current up (6A ± 0.1A), the protection circuit will quickly action within 6.7-13.9ms, to cut off access, overcurrent protection.

About some batteries turn green but can not reach 8.4V description:

Because the self-assembly of the battery under normal circumstances is not strictly paired sub-capacity, short barrel plate according to the principle of one section of the worst battery voltage and determines the overall performance of the battery, so unless it is strictly paired (voltage resistance capacity) exactly the same battery can be fully charged to 8.4V, the other self-paired battery can only be reached within the normal range of 8.2V ~ 8.3V, of course, does not exclude the unpaired battery voltage lower case turn on the lamp, this module uses professional battery management chip , responsible for the overall safety of the battery, it is for security reasons, not the protective plate quality problems!
