Product Storage
- 1The external terminals of the battery pack are in an insulated and protected state.
- 2Battery packs with a storage period of more than 6 months should be replenished accordingly, turn on the battery switch, the indicator light is on, when the power is 30%-50%, charge with 0.2C for 1 hour; when the power is 30% and below, charge with 0.2C for 3 hours.
- 3Don't store or place the battery under 60 degrees high temperature for a long time, otherwise it will cause function decline and life span reduction.
Installation Precautions
(1) Unpack the box, check the number of accessories and the appearance of the battery before installation.
(2) Hang the bracket, read the battery voltage on the display, generally the factory voltage is between 25.2V-26.75V (20%-60%).
(3) Check the positive and negative terminals of the battery before wiring, it is strictly prohibited to reverse the positive and negative terminals when installing the battery.
(4) Wear protective gloves during the battery connection process. When using metal tools such as torque wrenches, please insulate and pack the metal tools to avoid the ends of torque wrenches and other metal tools touching the positive and negative terminals of the battery at the same time, which may cause the battery to be short-circuited.
(5) Before connecting the battery to external equipment, disconnect the equipment and check the polarity and total voltage of the battery again to see if they are correct. Then connect the positive terminal of the battery to the positive terminal of the equipment, and the negative terminal of the battery to the negative terminal of the equipment, and fasten the connecting wires.
(6) Batteries must be handled and placed gently, and it is strictly prohibited to drop, impact, throw or knock the batteries to avoid damage to the batteries or lead to potential safety hazards.
(7) Prohibit the use of sharp parts of the tool to contact the surface of the battery box, scratches or damage to the battery box.
(8) Do not disassemble the battery box.
(9) Do not put any metal or electrically conductive objects together with the battery or assemble them into the battery box.
(10) Make sure the wall meets the wall mounting requirements before installation.
