Innovation

The new extended capacity lithium battery can be used with X Series carts of all ages. The battery is designed to be used on longer more hilly type courses and offers a 30% increase on the standard Lithium Battery.
The battery is protected by a sophisticated battery management system (BMS) that constantly monitors every cell to ensure the battery is always optimized for best performance and life. It is supplied complete with battery lead and protective neoprene case.
You will note that the lithium battery is supplied with blue/black connectors, whereas your cart may be fitted with red/black connectors. This change has been made to emphasize the importance of using the correct battery charger with this battery - using the wrong charger could damage the battery.
We are unable to guarantee that this is a 36 hole battery, but it should be good for 36 holes based on our average measurements. During testing of the battery with the Stewart Golf X9, its average use was 12-15Ah of the battery per round of golf. However there are a number of variables that are in your control as the golfer that will effect consumption. The theory is no different to fuel consumption in a car. Your car may be able to make say 500 miles on a tank of fuel, but equally if it is driven inefficiently or loaded down, it may only achieve 300 miles sometimes.

User must charge battery with Stewart Golf charger to avoid the risk of damaging cells which will also void any warranty.
