Stewart Golf ULTRA Lithium Battery and Charger (X Series) Stewart Golf

The new Stewart Golf ULTRA extended capacity lithium battery & charger can be used with X-Series trolleys of all ages. The battery is designed to be used on longer more hilly type courses and offers a 50% increase on the standard Lithium Battery.

The new Lithium Phosphate 30Ah battery has been developed as a true 12V battery, which means that it can be used in any X Series (X1, X3, X5, X7 or X9). There are no electronics changes or adjustments necessary; you can just start using the new battery as a direct replacement.

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 trolley 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.

DO NOT USE A LEAD-ACID CHARGER WITH THIS BATTERY. ONLY USE THE CORRECT CHARGER AS SUPPLIED BY STEWART GOLF. (THE LITHIUM BATTERY CAN ONLY BE CHARGED WITH THE BATTERY CHARGER THAT HAS THE BLACK/BLUE OR BLACK/RED TORBURY CONNECTORS) 

Is this a 36 hole 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 kilometers on a tank of fuel, but equally if it is driven inefficiently or loaded down, it may only achieve 300 kilometers sometimes. 

• 18 holes of golf is not a finite measurement. There can be a difference of several kilometers from a short to a long course (taking the distance between green and tee in to account too). 
• Terrain, ground condition, bag weight, and a number of other factors can make a big difference. Imagine running along a flat concrete road as opposed to up a steep sand dune & you’ll get the idea. 
• The quality of the golf also affects how far you walk. A golfer shooting 65 will walk a lot less than a golfer shooting 110 and zig-zagging up the fairways! This scenario would also see the steering being used more, which also consumes more power.

• In laboratory conditions over 1000 simulated golf cycles, the battery can be expected to lose 15% capacity.
• The battery can be expect to lose 2-3% capacity per year through cell degradation, compared with a lead/acid battery which can lose 8-9% per year.
• During testing of the battery with the Stewart Golf X-Series , its average use was 12-15Ah of the battery per round of golf.
