The engineer teaches you to use a 3.7V 10Ah lithium polymer battery to make a 12V 10Ah motorcycle starting battery.How to make a 12V 10Ah motorcycle starter battery with 10Ah lithium polymer cells?
Engineer production steps:
Step 1: Check the battery cells, use the tester to test the voltage of the 3 battery cells, and record the data
Step 2: Fix the 3 batteries side by side with 3M glue
Step 3: Solder and fix the prepared PCB (battery protection board) to a suitable position on the top of the battery pack, and check the solder joints
Step 4: Test again the battery pack voltage after installing the protection board
Step 5: Weld the two wires to the positive and negative solder joints of the battery pack PCB respectively
Step 6: Insulate with Highland Barley paper
Step 7: Install the insulated battery pack into the prepared ABS shell
Step 8: Fix the battery pack with glue
Step 9: Reinforce the battery pack with high temperature and fireproof epoxy board
Step 10: Weld the positive and negative terminals
Step 11: fix the shell cover with a glue gun to package.
Step 12: Use a comprehensive tester to test battery voltage and discharge
