With equalization, the same port 30A, 4-16 string universal, can be directly downgraded, no need toScope of application: 18650 special lithium battery protection board, scooter, drift car protection board, solar street light, LED protection board, motorcycle lithium battery protection board, tricycle power protection board, backup power lithium battery protection boardContinuous Discharge Current: 30AInstantaneous discharge current:100ACharging voltage: 60VMaximum charging current: 30AOvercharge detection voltage: 3.750.025VOvercharge protection delay: 10030msOvercharge release voltage: 3.60.05VBattery balance detection voltage: 3.60.025VBattery balance release voltage: 3.60.05VBattery balance current: 365AOverdischarge detection voltage: 2.10.08VOverdischarge detection delay: 100msOverdischarge release voltage: 2.30.1VOvercurrent detection voltage: 150mVOvercurrent detection delay: 10msOvercurrent protection current: 13020AOvercurrent protection release condition: disconnect loadShort circuit protection condition: external load short circuitShort circuit detection delay: 200uSShort circuit protection release condition: disconnect loadMain circuit conduction internal resistance: less than equal 15mWorking current: less than equal 50uASleep current (when the battery is over-discharged): less than equal 10uATemperature range: -30/+80CSize: 80*55*10mmcolour:Silver + greenMaterial:Metal + PCBConnection Using:1. First connect the B- line to the battery negative terminal (the B- line must be soldered with a short wire), and then connect the flat cable (before connecting the flat cable, be sure to unplug the flat cable from the board)2. Start wiring from B-, connect B- to the total negative electrode of the battery, connect the second cable B-1 to the first positive electrode of battery, and connect the third cable B-2 to the second positive electrode of battery, and the fourth cable B-3 is connected to the third positive electrode of battery...and so on3. Finally, measure whether the total battery voltage is equal to the output voltage of the protection board, and the protection board works normally if it is equal.Package Contents:1 * Li-ion Battery Protection Board1 * Cabel wireOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
