A resort rents out 50 golf carts that were all converted to lithium in the same month. The finance manager worries that all packs will need replacing in the same season and wants a plan that spreads the cost and avoids a fleet without carts.
Track the health of each pack, rotate usage so packs age at different rates where useful, and replace in yearly waves based on measured capacity, not calendar age alone. Set a capacity threshold at which a pack moves to lighter duty and another at which it is replaced. Budget each year for a share of the fleet, and keep a few spare packs so a failure never takes a cart out of service for long.
Build the data first
- Register each pack. Serial number, cart number, install date and charger.
- Track use. Cycle count, energy used and alarms from the BMS app or display; Redway lists Bluetooth, app, LCD and 4G options.
- Test capacity yearly. A supervised full charge and discharge on a sample of carts, or BMS capacity estimates where available.
Turn it into a plan
- Grade packs. For example: full duty, light duty (shorter routes or backup carts), and replace.
- Rotate. Move the strongest packs to the busiest carts so that weak packs are not pushed to failure in peak season.
- Replace in waves. Plan replacements over several years instead of all at once, starting with the weakest packs.
- Keep spares. Two or three spare packs cover failures while a replacement is ordered. Our reorder planning article covers lead times.
Warranty and life figures
Redway’s golf cart warranty is 3 years, and 5 years on the 48V 100Ah model. Redway uses 4000 cycles as the cycle-life figure for planning. Real life depends on depth of discharge, temperature, charging and how the carts are used, so let your capacity tests guide decisions. See Redway’s testing and replacement page and fleet battery page.
A simple yearly cycle
Before peak season: capacity tests and grading. During the season: monitor alarms and rotate packs. After the season: order the next wave of replacements and spares. Repeat each year, adjusting the replacement share to what the tests show.
Risk limits
Do not run a pack that shows damage, heat, swelling or repeated protection trips, whatever its age. Life figures are planning values, not guarantees; follow your written warranty terms.
Additional perspectives
Put battery replacement into the yearly budget as a fixed line for a share of the fleet. It is easier to approve a steady amount than a large surprise in year five or six.
Redway Tech Editorial Team – Finance manager perspective
Write the pack serial number on the cart’s service sheet. When packs move between carts during rotation, the record must follow the pack, not the cart.
Redway Tech Editorial Team – Fleet supervisor perspective
Run capacity tests before peak season, not during it. You want to find weak packs while there is time to move or replace them.
