RoyPower USA Technology Co is the manufacture of a 48 volt Lithium Battery Pack for Golf Carts
This post is specifically about three models of 48 volt golf cart battery packs offered by RoyPow. Note 48 volt is a nominal voltage language used to identify a cart. The actual voltage of the RoyPow battery pack is 51.6 volts and is offered in three capacities.
Think of the two capacity options as “small 56Ah” and “medium 105Ah” and “large 160Ah”
RoyPow says the S series 51V 56Ah 2.86kWh lithium battery pack model has an operating range of 20-30 miles on a full charge, flat terrain and one passenger.
The 51V 105Ah 5.37kWh lithium battery pack model has an estimated operating range of 40-50 miles and weighs 95lbs. Note: four lead acid 12v golf cart batteries have a combined weight of 328lbs.
The largest, p/n S51160 51V 160Ah has an operating range of 60 to 80 miles on a full charge, again on flat terrain and one passenger.

Less battery weight increases performance and is less stress on the golf carts bushings and brakes
Most Golf Carts will travel uphill better due to reduced weight
Installation time 2-3 hours on average
Lithium Golf Cart Battery vs Lead Acid Golf Cart Battery Talking Points
Lithium Pack vs Lead Acid
Faster Recharging time 2.5 hours vs 6-8 hours for lead acid batteries
5 year warranty vs 2 year warranty
10+ year battery life vs 4-5 year life
3500+ cycles vs 500-600 cycles for lead acid batteries.
If you discharged and recharged the Lithium Battery pack everyday for ten years, after the tenth year approx 50% of the capacity would be available.
PSOC Partial State of Charge and Lead Acid Batteries
“It is important for lead-acid batteries to be maintained fully charged. During discharge, small crystals of lead sulfate are created on the battery plates and are dissolved again during recharge. Leaving the battery uncharged, the crystals gradually re-crystalize to larger ones, difficult to dissolve, thus preventing the battery to recharge, practically reducing its capacitance. This phenomenon is called sulfation and is the major factor for early battery degradation.” from article
Lithium does not suffer the PSOC

The weight of the lithium battery pack is 90 lbs vs 328lbs. The weight reduction will help the speed of the cart when pulling hills.
In addition, the bushings and brakes on the golf cart will last longer due to the reduced weight.
So, Are Lithium (Lithium Iron Phosphate) Golf Cart Batteries Going to Replace Lead?
For these reasons, we believe the answer is yes.
- Traditional lead acid batteries last on ave 5 years. So having to pay labor and parts less frequently is a huge plus.
- Resale value of the golf cart will be higher. New buyers are always weary of battery life.
- Higher range with lithium. Four 12 Volt batteries have a range of about 12 miles.
Compare that to 30 to 90 miles on a full charge (depending on battery model).
- Monitor the battery capacity easily. A simple battery monitor with a shunt can be added to display battery capacity. The least expensive unit is $50 on Amazon, and a top quality item by Victron with bluetooth BMV-712 $204
