Step-by-Step Guide:

Step 1: Battery Pack Setup
• Connect 6 lithium-ion batteries in 3S2P configuration:
• 3 batteries in series = 11.1V (3.7V x 3)
• Then make 2 of these series sets in parallel to double the capacity.
• Connect the BMS to protect and manage charging/discharging.
• Use spot welding or strong soldering for the connections.

Step 2: Electrical Box Preparation
• Drill holes for:
• Switches
• DC charging port
• LED outputs
• Make sure the box can safely house the battery and all components without shorting.

Step 3: LED Light Setup
• Mount the bike LED light at the front of the box.
• Mount the DOB LED lights around or inside for area lighting or side light feature.
• Wire them with separate switches so they can be controlled independently.

Step 4: Wiring
• Connect the positive and negative terminals from the battery to:
• Switch 1 → Bike LED light
• Switch 2 → DOB LEDs (all 3 in parallel)
• Connect the DC socket to the battery input through the BMS for charging (make sure your charger matches the BMS voltage and current).

Step 5: Final Assembly
• Carefully place all components into the electrical box.
• Use hot glue or brackets to secure the battery and electronics.
• Close the box and test each switch and LED.


Safety Tips:
• Always test the battery voltage and connections before finalizing.
• Use insulation on exposed wires.
• Ensure the BMS matches your battery pack configuration (3S for 11.1V).
• Avoid over-discharging or overcharging lithium batteries.
