Frequently Asked Questions

Is this a 48V or 51.2V lithium battery?

It is a 51.2V nominal LiFePO₄ battery, commonly marketed as a 48V lithium battery. It may work with compatible 48V vehicles and power systems, but the controller, charger and operating-voltage range must be confirmed before installation.

Should I choose the 100Ah or 150Ah model?

Choose the 100Ah / 5.12kWh model for a lighter, more compact battery suitable for most golf carts and selected Ryobi 48V mower conversions. Choose the 150Ah / 7.68kWh model when you have sufficient installation space and need 50% more stored energy for longer runtime.

l 100Ah: 593 × 266 × 216mm | 41kg

l 150Ah: 680 × 320 × 262mm | 63.2kg

Which 48V golf carts are compatible?

These batteries may suit many 48V Club Car, E-Z-GO, Yamaha, ICON and Star EV golf carts, including selected DS, Precedent, TXT and RXV models. Compatibility depends on the model year, battery compartment, controller, wiring and charger, so always measure the installation space before ordering.

Can one lithium battery replace my complete lead-acid battery bank?

Yes. One compatible 51.2V battery can replace a complete 48V lead-acid bank, such as eight 6V, six 8V or four 12V batteries. Remove the entire lead-acid bank and never mix lithium and lead-acid batteries in the same system.

Some vehicles may require new cables, mounting brackets, connector adaptors or an onboard-charger bypass.

Can this battery be used in a Ryobi 48V ride-on mower?

The 100Ah model may be considered for selected Ryobi 48V mower conversions, including the RM300E, RM480E and RY48ZTR100. These conversions are not guaranteed to be plug-and-play and may require mounting hardware, cable adaptors, a pre-charge circuit and a compatible lithium charger.

It is not suitable for Ryobi 80V ride-on mowers.

Can it be used in an RV, caravan, Polaris UTV, ATV or mobility scooter?

It may suit compatible 48V RV/caravan systems, electric Polaris UTVs, ATVs, mobility scooters and low-speed utility vehicles. Before ordering, confirm the system voltage, controller or inverter requirements, peak current, charger, terminal orientation and available installation space.

This is a deep-cycle battery and is not designed to start petrol or diesel engines.
