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,
1. Lithium Polymer Battery Precautions and Safety Instructions
(1)Guarantee to keep the battery in good repair in 12 months from the shipment.
(2)Please use 0.5C current to charge up 60% capacity after the battery placed 3 months.
(3)Before Use the battery, carefully read the instruction manual and battery labels on the surface.
(4)Need to use the original battery charger, and should be placed in a dry ventilated place.
(5)Such as long-term when not in use, the battery charger to charge state half full, remove the battery from the device and separated, to avoid metal contact with the battery, causing
short-circuit or damage to the phenomenon.
(6)In use or during storage, battery found there has been high fever, leakage, odor, distortion and other anomalies, please stop using it immediately and stay away from the battery.
(7)Do not short-circuit the battery positive and negative, and careful not to allow the battery to moisture, to avoid danger.
(8)Using, keep away from heat, High pressure place, and do not beat, hit the battery.
(9)Battery end of life should be immediately removed from the equipment, Please properly handle security of spent batteries, do not put into fire or water.
(10) Shocks, high temperature, or contacts of sharp edge components should not be allowed in battery pack assembling process.
2.Storage of Lithium Polymer Battery
(1)Batteries should be charged to about 30% to 50% of capacity.
(2)Indoor storage in cool conditions without direct sun light on the packs or cartons.
(3)Store batteries in a dry location with low humidity, and a temperature range of –20°C to +30°C.
(4) Long-term storage can accelerate batteries self-discharge and lead to the deactivation of the batteries.To minimize the deactivation effect,store batteries in atemperature range of +10°C to +30°C. (5) When charging for the first time after long-term storage,deactivation of batteries may have led to decreased capacity.Recover such batteries to original performance through repeating several cycles of fully charging and discharging. (6) When storing batteries for more than 6 months,charge at least once every 6 months to prevent leakage and deterioration in performance due to self-discharging
1.Q: What is CC/CV?
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
max acceleration: 30m/s2
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
