Protection function description
Overcharge protection: When the battery is under the charging state, the voltage keeps going up. When the protection board detects that the voltage of any cell is higher than the overcharge protection value, the protection board will start timing immediately. When the time reaches the overcharge protection delay, the protection board will turn off the charging MOS tube, at that time, it cannot be charged.
Overcharge protection recovery: After the overvoltage protection appears on the protection board, the battery voltage will going down under the static or discharge state of the battery. When the protection board detects that each voltage is lower than the recovery voltage of the overcharge protection, the protection board will output a signal and turn on the charging MOS tube to charge.
Over-discharge protection: When the battery is under the discharge state, the voltage keeps going down. When the protection board detects that the voltage of any cell is lower than the overcharge protection value, the protection board will start timing immediately. When the time reaches the over discharge protection delay, the output signal of the protection board will turn off the discharge MOS tube, the load lock circuit will work, but, it cannot discharge at this time.
Over discharge protection recovery: After the over discharge protection appears on the protection board, the battery voltage will going up under the static or discharge state of the battery. When the protection board detects that each voltage is higher than the recovery voltage of the over discharge protection. At this time, disconnect the load or charge, the protection board will output a signal and turn on the charging MOS tube to charge.
Overcurrent protection: When the battery is under the static or discharge state, the current suddenly increases. When the
protection board detects that the current reaches the overcurrent protection value, the protection board will start timing at that time. When the current duration in the circuit reaches the overcurrent protection delay time, the output signal of the protection board will turn off the discharge MOS tube, and the load lock circuit will work. At this time, the discharge cannot be conducted.
Overcharge protection: When the battery is under the charging state, the voltage keeps going up. When the protection board detects that the voltage of any cell is higher than the overcharge protection value, the protection board will start timing immediately. When the time reaches the overcharge protection delay, the protection board will turn off the charging MOS tube, at that time, it cannot be charged.

At this time, the discharge cannot be conducted.
Overcurrent protection recovery: After the discharge overcurrent protection appears on the protection board, the discharge MOS tube is turned off, and the current in the loop becomes 0. At this time, the load is disconnected or charged, the output signal of the protection board will turn on the discharge MOS tube to discharge.
matters need attention.
Please note: please make sure the B-thick wire be weld first, then continue to connect other wires, B- wire welding too thin too long or not welding will burn the board! It must be welded with thick short wires!
1. Before installing protection board, the battery must be matched well (each battery voltage difference is not higher than 0.05V, each internal resistance difference can not more than 5 m Ω, and difference of capacity is less than 30 mah), if it is a polymer battery, the voltage should be between 3 to 4 V, if is the lithium iron phosphate battery, the voltage should be between 2.6 and 3.5 V, if it is on the high voltage, protection board may protect, which will causes the protection board can't work normally, if the battery capacity is full, please turn down the voltage to requirement range, and then connect the protection board, the battery should be connected in parallel and then in series. The more consistent the battery is, the farther it can run, and the best performance of the protective plate is achieved.
2. Wiring sequence: connect the B-wire to the total negative electrode of the battery (the B-wire must be welded with thick short wire) and then connect the flexible flat wire, which must be pluck-out from the board before connect , starting from BC0 wiring, the first flexible flat wire BC0 connect to total negative electrode of the battery, the second flexible flat wire connect to the anode of first series battery, The third wire is connected to the anode of second series battery, and the fourth wire is connected to the anode of the third series battery.... And so on, after the wiring is connected, start to measure the voltage between two adjacent wire, The polymer battery voltage must be less than 4V ,and if the iron lithium battery voltage must be less than 3.5v, double check the wiring sequence, then plug the flexible flat wire, then put the charger's cathode and electronic load cathode on C-. No matter how many protection boards you buy, we will fit it before send out,. Please do not change the number of boards causally, B cathode wire and C cathode wire must be welded with thick wire.
3. Finally, measured the total voltage of the battery, to verify that it is equal to the output voltage of the protection board.
if the output voltage is equal to total voltage of the battery, the protection board will work normally. must double check the
wiring before use.(if the total battery voltage is not equal to the output voltage, please review the above steps to see if there is any operation error.
4. Must use lithium battery chargers for lithium battery charging, do not use lead-acid battery charger, because the lead-acid batteries are likely to have high voltage which will breakdown MOS of protection board, charging voltage must be stable, because the unstable have high input voltage, which will breakdown MOS , it is easy to cause overcharge protection fail. Polymer battery charger voltage: battery series quantity * 4.2v; Ferrolithium battery charger voltage: battery series quantity * 3.6v.
