Battery balance detection voltage: 3.60.025V. Battery balance release voltage: 3.60.05V. Battery balance current: 365A. Overdischarge detection voltage: 2.10.08V.Overdischarge detection delay: 100ms. Overdischarge release voltage: 2.30.1V. Overcurrent detection voltage: 150mV. Overcurrent detection delay: 10ms. Overcurrent protection current: 13020A. Overcurrent protection release condition: disconnect load. Short circuit protection condition: external load short circuit Short circuit detection delay: 200uS Short circuit protection release condition: disconnect load Main circuit conduction internal resistance: less than equal 15mohm Working current: less than equal 50uA current (when the battery is over-discharged): less than equal 10uA Temperature range: -30/+80C Connection Using: 1. First the B- line to the battery negative terminal (the B- line must be soldered with a short wire), and then the flat cable (before connecting the flat cable, be to unplug the flat cable from the board) 2. wiring from B-, B- to the negative electrode of the battery, the second cable B-1 to the first positive electrode of battery, and the third cable B-2 to the second positive electrode of battery, and the fourth cable B-3 is connected to the ird positive electrode of battery...and so on 3. Finally, measure whether the battery voltage is equal to the output voltage of the protection board, and the protection board works normally if it is equal. Please note: Different batches, product appearance and color may be different, does not affect the Colour:silver + green Material:Metal+PCB Size:80 x 55 x 10mm Package Contents: 1 x Protection Board 1 x Cable Only the above package content, other products are not included. Note: Light reflection and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
