A resort replaces lithium packs in its golf cart fleet one cart at a time as they wear, so the fleet now has packs of several ages. The fleet manager wants to avoid range complaints and keep track of which pack is where.
Mixed ages across a fleet are normal; mixing packs inside one cart is the risk to avoid. Track every pack by serial and install date, give the longest routes to the newest packs, keep each cart on one matched pack of the same model, and check chargers when new packs arrive. Use range and fault records to plan the next replacements in groups.
Rules that keep it simple
- One pack, one cart. Do not combine packs of different ages or models in series or parallel in one cart unless the supplier approves it.
- Track by serial. Record pack serial, install date and cart number.
- Match duty to age. Send newer packs on longer routes and use older ones for short runs.
- Charger check. Confirm chargers suit any new pack model or BMS version; see our charger selection article.
Watching performance
- Log range or rounds per charge for each cart.
- Note alarms and slow charging; see our fault log article.
- Compare carts of different pack ages on the same route each season.
Planning replacements
Replacing in groups simplifies stock and training. Our replacement cycle article explains how to plan. Redway’s golf cart packs list about 4000 cycles. Redway’s golf cart warranty is 3 years, and 5 years on the 48V 100Ah model. Redway’s testing and replacement page gives background.
Briefing the team
Tell drivers and staff why some carts go on longer routes, and make the routing rule simple to follow. Share the pack list with your service provider before each visit, so older packs get checked first.
Risk limits
Connecting packs of different ages or models together can cause imbalance and protection trips. Follow the supplier’s instructions for your model. This article is general guidance for fleet managers.
Additional perspectives
Put the pack’s install year on a small label in the cart. Staff then route carts without checking the system.

When a new BMS version arrives, check the display and charger on the first cart before fitting the rest.

Plan replacements in groups of carts. One purchase order and one training session cost less than ten.
