Upper limit working current: 0A
Working temperature: -40--- 50 ?C
Upper limit instantaneous current: 0A
Storage conditions: -40-- 80 ? C
Quiescent current: less than 0uA
Effective life: more than 50,000 hours
Internal resistance: less than 00m?
Short circuit protection: protection, charge recovery
Charging voltage 6.8V-V
Note:
Strictly follow the diagram wiring 0V (B-), .7V (B), 7.4V (B), .V (B), 4.8V (B ), do not intentionally short circuit!
After the line is connected, you need to charge it first to have output. (p p- is the input and output. When combining, the battery voltage, capacity and internal resistance should be paired well. After the group is assembled, it will be output with 6.8V voltage.)
When connecting 4 groups of batteries in series, please ensure that the voltage of each group of batteries is the same. If they are different, please fill each group of batteries separately and use them in series. In the discharge test, the battery with a fast voltage drop is a poor battery.
Do not mix good battery and poor battery! The closer the capacity/internal resistance of the 4 batteries is, the better! (The effect of good batteries poor batteries = the effect of 4 poor batteries).
We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution.
