Lithium Golf Cart Conversion

Summary — Lithium golf cart conversion (DIY / tutorial)

This video demonstrates a step-by-step conversion of a golf cart from lead‑acid batteries to a LiFePO4 (lithium iron phosphate) pack. The project is sponsored by Power Queen and uses their golf‑cart-specific components.

What the video covers

• Full conversion procedure from lead‑acid to LiFePO4
• Installation of Power Queen hardware and use of their charger
• Wiring, safety checks, and a test drive to verify performance
• Demonstration of the battery monitoring app and telemetry features

Products & specifications

• Power Queen Golf Cart Smart Edition battery
  • 51.2 V, 100 Ah LiFePO4
  • Bluetooth-enabled with a phone app/battery monitor (shows state of charge and other battery data)
  • Designed to mount in the cart dash
• Power Queen charger
  • Approximately 58.4 V, 18 A (made for their golf cart batteries)

Key technological concepts & product features

• LiFePO4 chemistry: substantially lighter and more energy-dense than lead‑acid; this conversion saved about 288.6 lb.
• Smart battery features: onboard telemetry, Bluetooth connectivity, and a mobile app for monitoring battery status and health.
• Charger compatibility: use a charger matched to the battery voltage and chemistry (manufacturer-supplied charger recommended).

Practical steps / tutorial notes (procedure used)

1. Remove the seat and set the cart to “tow” (safety mode) before disconnecting any batteries.
2. Remove the old lead‑acid batteries.
3. Install the LiFePO4 pack in the dash area and secure the mounting hardware.
4. Wiring layout (as described in the video):
   • Battery positive (hot) → bus bar for positives.
   • Battery negative → through the shunt (for current sensing/monitoring) → negative bus bar.
   • Battery monitor plugs into the shunt/current sensing circuit.
   • Charger connects to the positive and negative bus bars (observe correct polarity).
   • Route an additional hot wire as needed to the cart’s systems.
5. Perform system checks, then test drive — the cart displayed noticeably improved acceleration and response.

Performance & outcomes

• Large weight reduction (~288.6 lb), which can improve range, acceleration, and handling.
• Successful system test — the cart started and drove properly after installation.
• Real-time monitoring of battery health and state-of-charge via the Power Queen app.

Notes & cautions

• Use the correct charger and match polarity and shunt wiring for proper monitoring and safe operation.
• Put the cart in tow/run safety mode before working on batteries.
• Ensure secure mounting and tidy cable routing to avoid loose connections and potential hazards.
