• The following tools are required to install the battery pack

Screw Driver

NOTE
Use properly insulated tools to prevent accidental electric shock or short circuits. If insulated tools are not available, cover the entire exposed metal surfaces of the available tools, except their tips, with electrical tape.

Safety protection

It is recommended to wear the following safety gear when dealing with the battery pack

Warning

1. Please read the manual and battery specifications carefully before commissioning the system.
2. Please use the batteries in a normal environment, charge temperature is 0℃~45℃, discharge temperature -20℃~60℃and the relative humidity is 65%±20%.
3. During their use, the batteries should be kept away from heat sources and high voltages, children should not be allowed to play with them, and they should not be knocked violently.
4. If the battery is to be used in other devices, please consult with the supplier about the degree of perfection of its protective function, Do not make arbitrary decisions to use battery in other devices.
5. The manufacturer will not replace the battery free of charge even in the warranty period if the problem with the battery results from misuse rather than bad quality.
6. If the battery is to be used in other devices, please consult with the supplier about the degree of perfection of its protective function. You should at least have a clear knowledge of such issues as the heavy current, fast charging and special application of the battery.

Against risk

1. There are a protective mechanism and a protective circuit inside the battery, which helps prevent danger. Improper disassembly of the battery can damage the protective function of the battery and therefore cause the battery to heat, smoke, deform or even burn.
2. Do not short-circuit the positive and negative poles of the battery with metal and do not store or move the batteries together with metal sheets either. If the battery is short-circuited, a heavy current will run through the battery, which will damage it and cause it to heat, smoke, deform and even burn.
3. he installation must be carried out in accordance with safety specifications to avoid personal and property losses.

Dangerous mode
The customer acknowledges there are in the process of operation and use of battery potential dangers:

1. The operator during operation may be limited by chemical damage, electric shock or electric arc. Higher than 50V/DC voltage damages serious, harm of the human body so the customer must to be conservative in the operation to avoid current damage.
2. Chemical risks from the electrolyte in the battery.
3. In battery operation and selecting personal protective equipment, the customer must consider more than the potential risks, to prevent accidental short circuits, electric arcs, explosions or thermal runaways.
