Custom Lithium Batteries for Golf Carts and Low-Speed Vehicles
48V to 144V LiFePO4 traction packs for golf carts, utility carts, UTVs, tuk-tuks and low-speed vehicles. For fleet operators replacing lead-acid, and for vehicle makers who need a pack designed around their controller, chassis and charger.
Vehicles we build packs for
| Vehicle | Systeemspanning | Wat drijft het ontwerp | Referentiepakketten |
|---|---|---|---|
| Golf carts (fleet and private) | 48 V | Rounds per charge, drop-in fit to the existing tray, charger compatibility | 48V 100Ah · 48V 105Ah 48V 150Ah · 48V 210Ah |
| Tuk-tuks, e-tricycles and UTVs | 72V | Battery swapping, payload, hill climbing | 72V 210Ah (swappable) |
| Long-range carts and shuttles | 72V | All-day range for resorts and campuses | 72V 608Ah |
| High-voltage low-speed vehicles | 96V – 144V | Higher motor power at lower current, vehicle-maker integration | 96V 210Ah 144V 520Ah |
Sizing a pack for range
Range depends on the vehicle, not the battery label. The most reliable number is watt-hours per mile (or km) measured on your own route, with your typical load and hills. A 48V golf motor typically draws 50–70A at around 15 mph on the flat, more on hills and during acceleration, so a hilly course can use far more energy per mile than a flat one.
- Measured consumption on the course, averaged over a round:
110 Wh/mile - Target per charge: two 18-hole rounds plus driving to and from the clubhouse ≈
30 miles→3.3 kWh - Usable at 90% and 20% ageing margin → rated
3.3 ÷ (0.9 × 0.8) ≈ 4.6 kWh - At 16S LiFePO4 (51.2V nominal):
4,600 ÷ 51.2 ≈ 90 Ah
Matching the pack to the controller and charger
- Controller current
- The BMS continuous and peak current limits must exceed what the motor controller draws during acceleration and hill climbs, or the BMS will cut power on the steepest part of the course.
- Voltage window
- LiFePO4 holds a higher voltage than lead-acid for most of the discharge, so carts often feel faster. Confirm the controller’s maximum input voltage against the pack’s full-charge voltage.
- Regenerative braking
- Carts with regen push current back into the pack on descents. The BMS charge limit and the cells must accept it, especially when the pack is already full at the top of a hill.
- Oplader
- A lithium charger at the right voltage, or a reprogrammed existing charger. Lead-acid profiles with equalisation or float stages are not suitable.
- State of charge
- A meter or display driven by the BMS replaces voltage-based gauges, which read wrongly on lithium’s flat voltage curve.
- Normen
- Batteries for light electric vehicles are commonly assessed against UL 2271, with UN38.3 for transport. Which reports cover your exact design is confirmed at quotation.
Upgrading a fleet from lead-acid
What changes
- One pack replaces a series string of 6V, 8V or 12V lead-acid batteries
- No watering, no terminal corrosion, no equalising
- Lower weight, so less wear on the cart and the turf
- Partial charging between rounds does no harm
What to check first
- Tray dimensions and hold-down points
- Controller current and voltage limits
- Charger model and whether it can run a lithium profile
- Whether the cart uses regen braking
- Fleet size, so we can standardise one pack across models

Levertijd en bestelhoeveelheid
Op basis van een vergrendelde specificatie: monsters binnen 12-15 werkdagen als de cellen op voorraad zijn, 20-25 als de cellen moeten worden ingekocht; productie in 30-35 werkdagen. Vanaf het eerste ontwerpgesprek: ongeveer 4 weken voor een definitief ontwerp zonder nieuwe tooling, 8 tot 12 weken voor een typisch maatwerkproject, 14 tot 18 weken wanneer certificering in aanmerking komt. Hoe elke fase werkt: ontwikkelingsproces voor aangepaste accu's En onze productiemogelijkheden.
