Jtron 4 String Iron Phosphate Lithium Battery Protection Board - Blue
The protection board uses lithium iron phosphate rechargeable battery protection IC; 1. High-accuracy voltage detection circuit; 2. The terminal is connected charger with high withstand voltage devices; 3. Built-in three-stage overcurrent detection circuit (overcurrent 1£¬ overcurrent 2£¬ load short circuit); 4. Through the MOS transistor can control the battery charging and discharging; 5. Low standby current consumption. Welding Point: B + Connected battery cathode; B-Connected the battery negative; B1 Connected battery connection point between 1 and cell 2; B2 then the battery connection point between 2 and 3 batteries; B3 battery is connected to the battery connection points 3 and 4; P + Connected charge / discharge upright pole (charging terminal / discharge terminal shared); P-Connected charge / discharge terminal negative (charging terminal / discharge terminal share). Note: 1. Note that the input and output voltage£¬ and load current conditions£¬ the protection board power consumption does not exceed the allowable Power dissipation electrical parameters; 2. Pay particular attention to the load current can not work long hours between maximum continuous operating current and over-current protection current; 3. The situation is not likely to occur when you connect the battery discharging. In this case£¬ connect the charger can be restored to normal operation; 4. The battery over-charge and over-discharge of the battery mixed together in series£¬ the protective plate and the overcharge state of over-discharge state£¬ the battery can not be charged and discharged; 5. The protection board built-in electrostatic protection circuit£¬ but please do not hand protection when working in electrical panels to touch the plate£¬ so as to avoid damage from static electricity protection board.
