Manufacturing Process


1. Batteries purchasing:

  We use brand li-ion cell, like Samsung,LG


2. Batteries selecting:

   We will check the battery again to guarantee the gull and same capacity


3. Battery pairing:

  We will check the voltage for each battery and choose those batteries with same voltage to guarantee the life time.


4. Bracket assembling:

  We use brackets to assemble those batteries,Which is more firm and has efficient heat dissipation.


5.  Batteries welding

   We will weld those batteries with connecting sheet to reduce the heat.


6.  BMS welding

   We will choose high quality BMS board with overcharge, over discharge,over current, temperature, short circuit,and                  balance protections.Sheet to reduce the heating.


7. Aging test

   We will do the aging test to guarantee the steady charging and discharging.


8.  Epoxy Material Packaging

   We use thick epoxy material to encapsulate the batteries pack that make it stable,safe and beautiful.


9.  Tape seal

   We use high-temperature resistant tape to encapsulate the batteries pack with fixed action and prevent moisture functions.
