How to Make a Powerful Flashlight Using an Electrical Box || Electrical Box से Flashlight कैसे बनाएं

Here’s how you can make a powerful flashlight using an electrical box with the materials Materials Needed With Buy Links 1. Lithium-ion batteries (6 pcs, 3.7V each) https://amzn.to/3S2DqqU 2. Battery Management System (BMS) https://amzn.to/3YbUIp4 3. Two switches https://amzn.to/4lKq4Nw 4. Bike LED light https://amzn.to/3RsLaSZ 5. DOB LED lights (3 pieces) https://amzn.to/4461uAA 6. Electrical box (enclosure) 7. 12V female DC socket https://amzn.to/4lA6CmG 8. Wires 9. Basic tools (screwdriver, soldering iron, multimeter, wire cutter) 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. #diy #experiment #vdropdiy #howtomake
