4A-5A PCB BMS Protection Board for 4 Packs 18650 Li-ion lithium Battery Cell 
 
Note: If the correct welding, testing the output of non-output, use other ways to activate charging about protection board!
 
Overview:
Main IC uses the original "Ricoh" imported components. Overcharge, over discharge, over current, short circuit protection, for a variety of capacities in various shapes 3.7V lithium batteries. Japan Seiko protection IC, VISHAY, AOS, IR and other high-quality MOSFET, FR-4 plate low temperature coefficient, design, fine workmanship, testing and comprehensive. Compact, suitable for many of the requirements of highly integrated, low-cost applications to meet a wide range of performance requirements to ensure the absolute safety and reliability of the battery pack.

Main functions and features: over charge protection, over-discharge protection, short circuit protection, overcurrent protection.
 
The protective plate using Japan's Ricoh rechargeable lithium iron phosphate battery protection IC;
 
1) high-accuracy voltage detection circuit;
2) terminal of the charger using high voltage devices;
3) Built-in three-stage over current detection circuit (overc urrent 1, over current 2, load short circuit);
4) MOS transistor can be controlled by a battery charge and discharge;
5) low standby current consumption.
 
 
Function and Notice:
1. the lithium battery with protection board according to the wiring diagram connection, when the battery voltage is overcharge and over-discharge voltage between the voltage, and P +, P- charging 1 second, P + and P- output voltage of the battery voltage.
 
2. The battery charge function: between P + and P- plus charger to charge the battery, the battery voltage charge to overcharge detection voltage (4.25 0.025V), the protection circuit to cut off the charging path, to achieve overcharge protection.
 
3. Battery over-discharge protection: in between the P + and P- connected load to the battery discharge when the battery voltage drops to over-discharge voltage (2.7 0.05V), the protection circuit, shut off the discharge path to achieve the over-discharge protection.
 
4. Short circuit protection: When the P + and P- short circuit protection circuit will act quickly in 5-50uS, cut off access, short-circuit protection.
 
5.  Overcurrent protection function: When the V- terminal voltage of (0.15 0.02V), the protection circuit will act quickly in 6.7-13.9ms, cut off access, overcurrent protection.
 
Package Includes:
1x 4A-5A PCB BMS Protection Board
