Installation Guide & Precautions

⚠️ IMPORTANT SAFETY WARNINGS:

• Always disconnect power before battery installation or removal
• Verify correct voltage compatibility (7.2V/7.4V) with your device
• Check polarity markings before connecting
• Never force connectors - they should fit smoothly
• Keep battery away from metal objects to prevent short circuits

Before Installation:

• Power off device completely
• Verify battery dimensions fit your device compartment
• Check connector type matches your device
• Inspect battery for any damage or swelling
• Ensure battery voltage matches device requirements
• Have double-sided tape or velcro ready for securing (if needed)

Step-by-Step Installation:

1. Prepare Device: Open battery compartment or access panel
2. Remove Old Battery (if replacing): Disconnect connector carefully, note wire colors and polarity
3. Check Polarity: Identify positive (+) RED wire and negative (-) BLACK wire
4. Position New Battery: Place battery in compartment, ensure wires reach connector without strain
5. Secure Battery: Use double-sided tape, velcro, or battery holder to prevent movement
6. Connect Wires: Match polarity - RED to RED (+), BLACK to BLACK (-)
7. Verify Connection: Ensure connector is fully seated and secure
8. Route Wires: Arrange wires to avoid pinching when closing compartment
9. Close Compartment: Ensure no wires are caught or pinched
10. Test Device: Power on and verify proper operation

First Use After Installation:

• Charge battery fully before first use (2-3 hours)
• Use appropriate 2S Li-ion charger (8.4V)
• Monitor battery temperature during first charge
• Perform 2-3 full charge/discharge cycles for optimal performance

Installation Precautions & Safety Notes

Polarity Warning:

• ⚠️ CRITICAL: Reversing polarity can damage device or cause fire
• Always verify: RED wire = Positive (+), BLACK wire = Negative (-)
• Double-check connections before powering on
• If unsure, consult device manual or professional

Physical Installation:

• Ensure battery fits without forcing or bending
• Leave small air gap around battery for heat dissipation
• Secure battery to prevent movement during operation
• Avoid placing battery near heat sources or motors
• Do not stack batteries unless specifically designed for it

Connector Handling:

• Never pull on wires - grasp connector body when disconnecting
• Ensure connector pins are straight and undamaged
• Clean connector contacts if oxidized or dirty
• Do not modify or cut connector unless absolutely necessary

For RC Car Installation:

• Secure battery with velcro straps to prevent shifting during racing
• Position battery for optimal weight distribution
• Ensure battery doesn't interfere with steering or suspension
• Use battery tray or holder designed for your RC model
• Check battery security before each use

For Toy Installation:

• Ensure battery compartment has adequate ventilation
• Use insulating tape on exposed connections
• Keep battery away from moving parts
• Ensure compartment door closes securely

For Camera/Electronics Installation:

• Use anti-static precautions when working with electronics
• Ensure battery doesn't contact circuit boards directly
• Use insulating material between battery and electronics
• Verify voltage regulator compatibility if present

Post-Installation Checks

• ✔️ Device powers on normally
• ✔️ No unusual heat from battery or device
• ✔️ No burning smell or smoke
• ✔️ Battery is secure and doesn't rattle
• ✔️ All functions operate correctly
• ✔️ Charging works properly

If You Experience Problems:

• Device doesn't power on → Check polarity and connections
• Battery gets hot → Disconnect immediately, check for short circuit
• Reduced runtime → Fully charge battery, perform calibration cycle
• Charging issues → Verify charger voltage (8.4V for 2S)
