Description: One battery with one hanging plate and 6 M8 explosive screws
BMS（For reference only, the electronic components of different kinds shall exist
A: Communication:
RS232 communication
RS232
BMS can communicate with the upper computer through RS232 interface, so that
the upper computer can monitor variousbattery information, including battery
voltage, current, temperature, status and battery production information, etc.
Thedefault baud rate is 9600Bps.
- CAN communication.RS485 communication
- CAN: RS485
- CAN communication, default communication rate 500K;Dual RS485 ports enable you to view information. The default baud rate is 9600bps.If you need to communicate with the monitoring device over RS485, the monitoring device acts as the host and polls data based on the address.
C: Address setting
When packs are used in parallel, you can use the DIP switch on the BMS to set
the address to distinguish different Packs.Do not set the address to the same.
See the following table for the DEFINITION of THE BMS DIP switch.
Terminal
M6 screw for 100A with the pinch 16mm.

Caution and prohibition
Before using and handling the pack, see carefully attached “Handling Instruction for Rechargeable Lithium-ion battery pack” For safety reasons rechargeable batteries are not shipped in a low remaining capacity state. Charge before using. Do not connect multiple battery packs as parallel or serials for use. This might damage the battery pack, even your equipment.
Warranty
The manufacturer will be responsible for replacing the battery pack against defects or poor workmanship for 24 months from the date of shipping. Any other problem caused by malfunction of the equipment or misuse of the battery is covered under this warranty
Handling Instruction Guide for LiFePO4 Battery Pack
General
Battery packs supplied by Crown Micro have to be handled carefully
according to the specifications. Herearesomemore to be followed Crown Micro
Storage of pack
- a. The packs are requested to be stored under the following conditions: a. Indoor storage in cool circumstances without direct sunlight on the packs or cartons.
- b. Store batteries in a dry location with low humidity, and a temperature range of – 20℃to +30℃. In the case of long-term storage.
- C. long-term storage can accelerate battery self-discharge and lead to the deactivation of the batteries. To minimize the deactivation effect, store battery packs in a temperature range of +10℃to +30℃.
- d. When charging for the first time after long-term storage, deactivation of the packs may have led to decreased capacity. Recover such packs to their original performance by repeating several cycles of full charging and discharging.
- e. When storing packs for more than 6 months, charge at least once charring required per 6 months to prevent leakage and deterioration in performance due to self-discharging.
Charging pack
- a. Use a suitable charger with the specified voltage and current. We strongly recommend Crown Microsmart battery charger. We can recommend the usage or specification of the charger manufacturing. If you want together information about it, please contact us
- b. Never attempt reverse charging. Charring with polarity reversed can cause a reversal in battery polarity, causing gas pressure inside of the battery to rise, which can be lead to leakage of the batteries in the pack.
- c. Avoid overcharging. Repeated overcharging can be lead to deterioration in pack performance. Andover-heat occurred
- d. Charging efficiency drops at temperatures above 40℃
Protection from unexpected damage to pack
- a. (+) and/or (-) terminals must not be connected in metal wire, necklace, or chains. 。
- b. Do not drop packs from height in order to prevent them from possible malfunction or damage.
- c. Do not twist or bend packs in order to prevent possible damage
For Safety,
- a. Do not disassemble packs.
- b. Do not use a pack when something abnormal is found such as smells, deformation, discoloration, and soon.
- d. Do not reuse LiFePO4 cells or other parts after removing them from the packs.
- e. When the electrolyte leakage occurs, do not touch the liquid.
- f. Once watered, packs may have potential malfunctions. Do not use those packs.
- g. Do not have packs in the hot temperature (60℃or more).
- h. Do not put packs into the fire.
- i. Do not crush/nail pack.
- j. Do not apply solder directly to packs
