The Club Car DS was built from 1982 to 2013, and most electric DS carts from the mid-1990s on run a 48V lead-acid pack of six 8V batteries. Swapping that pack for lithium is the most popular DS upgrade: it drops hundreds of pounds, holds voltage better under load, and ends the watering routine. There are two very different ways to do it, and the right one depends on whether you also plan to change the motor and controller.
This guide compares a 48V drop-in lithium kit with a DIY pack built from reclaimed EV modules, using parts and prices from our parts database. Prices are what sellers listed when we last checked; always confirm on the seller's page.
Path 1: a 48V drop-in kit (keep the stock motor)
A drop-in kit replaces the lead-acid batteries at the same nominal voltage, so the stock motor, controller and wiring stay. The kit we track for the DS is the Epoch 48V 105Ah MINI Golf Cart Battery Complete Kit (BB51105A_MINI-kit-1) ($2,299). Epoch lists it at 51.2V nominal, 58.4V full, 105Ah (about 5.4 kWh) of LiFePO4, rated 200A continuous and 700A peak for two seconds. The seller says the kit includes a 48V charger, a 12V converter, a gauge and mounting brackets. Epoch lists a separate "MINI" kit for the DS, while its standard 105Ah kit (Epoch 48V 105Ah Golf Cart Battery Complete Kit (BB51105A-Kit) ($2,299)) is listed for the Precedent, TXT and RXV.
Another Club Car kit in our database is the RoyPow 48V 105Ah Lithium Battery Kit for Club Car (S51105) ($2,885). RoyPow lists it for Club Car, but we have not yet confirmed DS-specific fitment or its electrical specs, so check with the seller.
One thing to know before ordering: many Club Car carts use an onboard computer (OBC) that controls charging. Epoch notes that an OBC bypass may be needed on Club Car. Ask the seller which steps apply to your year.
Drop-in pros and cons
- Pros: one box, one order, a matched charger, minimal wiring changes, seller support, and no change to the cart's voltage class.
- Cons: top speed and torque stay close to stock, because the motor and controller are unchanged. Cost per kWh is higher than reclaimed modules.

Path 2: a DIY pack from reclaimed EV modules (with a motor upgrade)
Modules pulled from production EVs are built for high current and vibration, and per kWh they cost far less than new golf cart packs. The catch is voltage: the common modules stack to about 72-86V, not 48V, so this path only makes sense together with a 72V motor and controller. It is also a real electrical project, with a battery management system, contactor, precharge and fusing you choose and wire yourself.
Module options we track
| Pack | Series | Full charge (as listed) | Price as a pack |
|---|---|---|---|
| Jaguar I-Pace modules ×7 (21S pack) ($1,120) | 21S | 86.1V (4.1V/cell max per seller) | $1,120 |
| Audi Q8 e-tron modules ×7 (21S pack) ($1,043, specs unverified) | 21S | 86.1V at 4.10V/cell | $1,043 |
| Kia Niro EV Wave 2 modules ×5 (20S pack) ($995, specs unverified) | 20S | 84V | $995 |
The Greentec I-Pace listing publishes the most specs of these, including a 400A peak rating, which is why our Hill Climber build uses it. Sellers of the e-tron and Niro modules do not list a current rating, so those packs show as unverified in the planner. When a module seller publishes no current rating, treat any number you see elsewhere as an estimate.
What else a DIY pack needs
- BMS: sized for your series count and current, for example the JK BXP24S 500A Active Balance BMS ($275, specs unverified) (12-24S, 500A shunt).
- Main contactor: such as the TE EV200AAANA Contactor (economized) ($75, specs unverified).
- Precharge: such as the REC Precharge Module V3.1 (time-set) ($99). REC's manual calls for an external resistor at 72V; follow it.
- Main fuse and holder: a Class T fuse rated above your pack's full voltage, such as the Littelfuse JLLN400 Class T 400A fuse ($77.99) (125V DC) in a Blue Sea Systems 5502 Class T Fuse Block 225-400A ($48.99). See our Class T fuse and wire size guide.
- Charger: an adjustable one you can set below 100% to extend pack life, such as the Chi Charger Mini Universal Charger 450W ($175) (adjustable to 134.4V, about 5A at 84V per the seller, so it is slow on a big pack).
- 12V converter: the input range must cover the pack's whole voltage swing, from empty to full. A 21S NMC pack can sag to the high 60s, so a converter that shuts off below 72V will not work. The DC-DC converter 120W 72V to 12V with ACC (18-90V in) ($37) lists an 18-90V input.
- Motor and controller: a 72V motor and a controller whose absolute maximum is above your pack's full voltage. For example, the Fardriver ND721000 (Encoder) ($511, specs unverified) is a 72V-class controller with a 90V maximum per the seller, which is why we cap 21S packs at 4.10V per cell.
DIY pros and cons
- Pros: much more current and energy for the money, and it pairs with a motor upgrade for real performance gains.
- Cons: many more parts, custom boxes and mounting, and high-voltage wiring that should be done or inspected by a qualified professional.
Cost comparison
The drop-in kit's listed price covers the battery side completely. For the DIY path, the battery-side parts alone (pack, BMS, contactor, precharge, fuse, holder, charger and converter) add up quickly, and the motor and controller come on top. Open the Hill Climber build to see a live total and which prices are still unknown.
Which one should you choose?
- If you want a quieter, lighter cart with no change in speed, choose the drop-in kit.
- If you are already planning a 72V motor and controller and want strong hill climbing and range, a reclaimed EV-module pack is the value play, as long as you're ready for the extra parts and wiring.
Either way, check compatibility before you buy. The JuiceMyCart planner flags voltage, current, BMS and fitment conflicts between the parts you pick.
Professional install: high-voltage and high-current golf cart builds, and suspension and brake work, should be done or inspected by a qualified professional. This guide is general information only.
