protection: to protect and restore must charge Charging voltage: 8.4 v-9v The protection board size and device
description; The protective plate size is 46.7 * 23 *
3.15mm Welding point description: · B + battery anode; · B - connect battery negative
terminal; · MMB connect battery 1 to battery
2; · P + charging/discharge correct poles (charging
end/discharge end sharing); · P - charging/discharge terminal negative
terminal (charging end/discharge end sharing).
Applicable
scope: Suitable for lithium batteries with nominal voltage of 3.7V and full
voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without
limitation on the dimensions) Product Size: 45*15*3.4mm (Standard), 48*20*3.4mm
(Balancing) Charging voltage: 8.4V - 9.0V Continuous discharge current (upper
limit): 20A (If the cooling environment is not good, reduce the load current
use) Continuous charge current (upper limit): 10A Standard Edition: Suitable for
starting drills with currents up to 25A below 50W, or resistive loads below
168W. Balanced version: Suitable for starting currents below 25A and below 50W
power drills, or resistive loads below 168W, with balanced charging function.
Note 1: The successful start of power drill requires two 10C-20C power
batteries, or four 5C-10C power batteries (ordinary 18650 can not start drill! !
!); 0V and 8.4V cable, use 2 square mm Above copper wire (cannot use nickel
plate!!!) Note 2: Connect 0V, 4.2V, 8.4V according to the diagram strictly. When
connecting the battery for the first time, it needs to be charged before output.
Note 3: When the battery is charged, “430” resistance heating is a normal
phenomenon, indicating that the equalizing circuit is working; if the “430”
resistance is also heating in the state of not charging, please check whether
the wrong line is connected. For some customers with poor electronic foundation,
please explain: Do not mix good batteries and bad batteries together! The
capacity/internal resistance of 2 batteries should be as close as possible! (1
good battery + 1 bad battery = 2 battery use effect).
