Safety Precaution:
1,Please strictly follow the directions to connect the PCB to the battery. Usually there's voltage in the battery at all time, so operator should connect one single line after other starting from terminal B, following the order from low voltage to high voltage, otherwise it can cause irreparable damage.
2,During the installation, pay attention to small metallic particles that can stick to the protection board.
3,Follow the standard rules when making connections between the protection board and the lithium-ion battery.Operator should not run any wire across the back of the protection board. Keep them along the side of the board instead.
4,When setting up the protection board, be sure to use a hard epoxy board as an interlayer, to prevent short-circuit caused by the components on the back of the protection board.
5,Both resistive load and inductive load can be used to test battery packs that use this PCB, but not electronic load. Testing with an electronic load will lead to the breakdown of the MOS components on the protection board.
6,Select proper wire gauge to prevent temperature increase from high discharge current (when wire gauge is too high) and excessive voltage drop (when wire gauge is too low).
7,When the PCB is to be installed inside the battery's housing, the user must fully take heat/electric insulation and tightness into account to prevent internal short circuit.
8,Keep any fully charged battery away from children.
9,If any abnormality is detected during use, please stop using the product immediately and notify professional technician to conduct inspection and maintenance.
