WARNINGS
- DO NOT immerse the battery in water or allow it to get wet.
- DO NOT use or store the battery near sources of heat such as a fire or heater.
- DO NOT reverse the positive (+) and negative (-) terminals.
- DO NOT connect the battery directly to wall outlets or car cigarette-lighter sockets without proper charging equipment. DO NOT allow exposed ends of cables connected to opposite terminals to touch.
- DO NOT put the battery into a fire or apply direct heat.
- DO NOT use the battery if the battery casing has been pierced, broken, cracked, or otherwise visibly damaged. DO NOT forcibly open the battery casing for any reason.
- Avoid severe physical shock. Do not throw the battery or heavily strike the battery in any way. Do not put excessive pressure or step on the battery.
- Never solder anything directly to the battery terminals.
- DO NOT attempt to disassemble or modify the battery in any way.
- DO NOT place the battery in a microwave oven or pressurized container.
- DO NOT use the battery in combination with primary batteries(such as dry-cell batteries) or batteries of different capacity, type or brand.
- DO NOT use the battery if it gives off an odor, generates heat, becomes discolored or deformed, or appears abnormal in any way. If the battery is in use or being recharged, remove it from the device or charger immediately and discontinue use.
- DO NOT use or store the battery where is exposed to extremely hot, such as under window of a car in direct sunlight in a hot day. Otherwise, the battery may be overheated. This can also reduce battery performance and/or shorten service life.
- If the battery leaks and electrolyte gets in your eyes, do not rub them. Instead, rinse them with clean running water and immediately seek medical attention. If left as is, electrolyte can cause eye injury.

DESCRIPTION OF COMMUNICATION AND PC SOFTWARE
Communication description RS485 1 communication, RS485 2 communication
The BMS uses RS485 communication to communicate with the designated upper
computer through a special communication box. The baud rate is 19200 bps by
default. Thus, various information of the battery can be viewed at the upper
computer terminal, including battery voltage, current, temperature, status,
SOC, SOH and battery production information.
Parameter settings and corresponding control operations can be carried out to
support the program upgrade function. Support the customer protocol (This
upper computer is applicable to the PC of Windows series platform.)
DIAL SWITCH ADDRESS SETTING
When the battery pack is used in parallel, different PACKs can be distinguished by hardware address, and the hardware address of each PACK in the whole battery stack is unique. The hardware address can be set in turn through the dial switch on the board, with 1, 2, 3, 4, dials. Refer to the following table for the definition of switches.
