Compared with conventional lead-acid batteries, LiFePO4 batteries offer longer cycle life, lower maintenance requirements, stable voltage output, and higher energy efficiency. The GLFB6 helps reduce battery servicing time and replacement frequency, supporting lower total operating costs over the battery’s service life.
For golf carts, this 12.8V battery should be used only in a properly designed series battery bank compatible with the vehicle’s required system voltage. Confirm dimensions, voltage configuration, charger compatibility, cable connections, and current requirements before installation.
Yes, it is designed for compatible 12V lead-acid or SLA battery systems. Always verify dimensions, terminal connections, charging profile, discharge-current requirements, and mounting space before purchase.
Yes, as part of a compatible multi-battery 12V series configuration. The final battery-bank voltage must match the golf cart’s electrical system.
The recommended charge current is 33A (0.2C). Use a LiFePO4-compatible charger that follows the specified 14.4V charging profile.
No water refilling or acid cleaning is required. Inspect cables, terminals, and charging equipment periodically to maintain reliable performance.
The battery is IP65-rated, meaning it is protected against dust and water jets. It must not be submerged in water.
