Is a 72V 100Ah, 160Ah or 200Ah golf cart battery right for a lifted or utility cart?

Direct answer: Start with the space and the controller, then size for the workload. The three packs share a 72V-class voltage window (87.6V maximum charge, 60V cut-off) but differ greatly: 7.68, 12.29 and 15.36 kWh, 72 to 125 kg, and 100A, 160A and 200A continuous. A lifted cart with big tyres or towing uses more energy and current per kilometre than a standard cart, which often favours the 160Ah or 200Ah pack, provided it fits and the controller suits it.

Page figures. 72V 100Ah (S72105P): 76.8V, 7.68 kWh, 740 × 320 × 246 mm, 72 kg, 100A continuous, 315A for 30s, stated range 97–113 km. 72V 160Ah (S72160P): 12.288 kWh, 960 × 446 × 217 mm, 88 kg, 160A continuous, 315A for 30s, 130–180 km. 72V 200Ah (S72210P): 15.36 kWh, 1138 × 410 × 253 mm, 125 kg, 200A continuous, 315A for 30s, 150–200 km. All list IP67, a metal shell and a 5-year warranty. Range conditions are not stated.

Fit first. The 200Ah pack is more than a metre long. Measure the frame or tray and check that the cart can carry the extra weight; a lifted cart’s frame and suspension may already be near their limits.

Controller. The controller must accept the full-charge voltage (87.6V) and its current limit should fit the pack’s continuous rating. If the controller can draw 300A for minutes on a climb with a trailer, the 100Ah pack at 100A continuous is the wrong match. Our post on standard vs high-current packs explains the same check at 48V.

Energy. Large tyres, lift kits, heavier loads, towing and off-road surfaces increase energy per kilometre. Measure kWh per day on a similar cart if you can, then add a reserve. The stated ranges are a poor guide for utility duty.

Wiring and heat. At 72V and up to 200A, cable size, lugs, the main fuse and the contactor must be rated for the current; check them at installation and at each service for heat marks. For 12V accessories, see DC-DC converters. When you ask for a quote, include the cart’s make and model, the controller’s voltage range and current limit, the tray or frame dimensions, the tyre size and how often it tows or climbs; with those details the supplier can confirm which of the three packs suits the cart, rather than choosing from the range figures alone.
