12V 110Ah battery pack for solar product I like your solar battery pack. Good quality and delivery fast.

—— Eyal Dolev

The battery pack is more atractive for us . May I receive drawing of other pack 12V 20AH with dimentional info ? I need 50pcs to test .

—— Nizamettin

We have received the battery packs and performing tests have passed . We are impressed by the assembly. it is almost the best one . thank you

—— Alexander Kozhushko

Pictures show a nice battery pack, performance is ok , We need serial connected 4cells (4S1P) configuration with protection circuitry

How to deal with the problem of unbalanced lithium-ion battery power?



Remove the protection board part of the lithium-ion battery, because repairing the unbalanced lithium-ion battery first needs to check the status of the lithium-ion battery, find the cells that affect the normal working of the whole group of batteries, this must bypass the battery protection board and directly measure the single cell Lithium batteries and record them;
2. Separately recharge the battery that has failed, or test the capacity separately, check whether the capacity and internal resistance of the battery are significantly different from the whole group of batteries. If the difference is not significant, you can recharge it separately, if the capacity already exists The difference between the internal resistance and the internal resistance means that it can only be replaced;
3. The battery pack that is repaired after recharging or replacing the monomer shall be subjected to a sub-capacity treatment of the battery cell part before reassembly to check whether the capacity meets the design requirements;
4. Restore the battery according to the original circuit, install the battery protection board and outer packaging;
Note: It is important to note that unbalanced lithium-ion batteries usually occur on the lithium-ion battery pack after a period of use, so the internal resistance of the entire battery pack will be different from that of the new battery. Special treatment is required when replacing the monomer. Replacing a brand new monomer may soon cause the problem to recure
