Precautions and Safety Instructions of Lithium Battery Pack
When the voltage between the two electrodes is over 36V, the safe voltage of human beings, you should not touch them with your body.
Storage of Lithium Battery Pack
1.The battery pack shall be storied within -10℃~45℃ range environmental condition.
2.If the battery pack has to be storied for a long time (Over 1 months),the environmental condition should be:
Temperature: 23±5℃
Humidity: 65±20%RH
3.The capacity is 80-90% of nominal capacity.
4.When storing battery packs for more than 6 months, charge at least once every 6 months to prevent leakage and deterioration in performance due to self-discharging.
We participate in a variety of trade fairs twice every year .On Electronics Show we discuss with customers
about our products and help them solve questions face to face.We have established contacts with many potential buyers from other places as America,Australia, Belgium, Israel,Germany,the Netherlands, Canada etc.
A: CC is constant current. CV is constant voltage.
2.Q: what functions can the BMS of the battery pack?
A: The BMS can Overcharge protection, Over discharge protection, Over current protection, Short circuit protection, Temperature protection. If you need more functions, please inform us and we can customized the BMS.
3.Q: What is vibration test?
A:Pack installed onto the vibration desk with clamps. Equipment parameters are as follows:
direction: up and down single vibration
frequency: 10~55Hz
max acceleration: 30m/s2
amplitude: 0.38mm
time: 10min.
During the test , Nickel film without shedding ,no scratch, the voltage is OK.
4.Q: What is drop test?
A:Packs dropped from a height of 0.5 meter to cement ground, packs shall be dropped in each of three
mutually perpendicular directions. Total drop times are 6.
After that, Nickel film without shedding, no scratch, the voltage is OK.
5.Q: How to use the battery pack correctly
A: When you use the battery pack, please notice as below:
Charge:Connecting the battery pack to the charge controller, connect the charger to recharge.
Discharge:Connecting the battery pack to the load ,connect the load to discharge.
When you combine the battery with series or parallels, if there are oxidation layer on the surface, you should brush surface to the metal glow with thin steel brush to lower the connective resistance to the minimal resistance.
When combining with many batteries, if the voltage between the two electrodes is over 36V, the safe voltage for human beings, to guarantee the safety, you should not touch the two electrodes with your body.
6.Q: What special cautions are there?
A: Due to the voltage between two electrodes over the safe voltage of human beings, nobody
should touch the two electrodes by his body in case of his safety. During using the battery,
you need insulate the two electrode terminals and also the part outside the metal conductor,
in order to prevent the short-circuit incident. You should do the related safety-prevention
work well.
