Lithium conversion has become the default answer to almost every golf cart question, and most of what is written about it is written by people selling the batteries. Here is the version that includes the parts nobody mentions until after you have ordered.
What actually changes
Weight. This is the biggest practical difference. A lead-acid pack can be 300 lb or more; a LiFePO4 pack of the same capacity is a fraction of that. Losing that mass changes acceleration, hill performance and how the suspension behaves.
Maintenance. Flooded lead-acid needs water checks and terminal cleaning. Lithium needs neither.
Charge time and cycle life. Lithium charges considerably faster and manufacturers quote cycle counts several times higher than lead-acid. Real-world life depends on how deeply you discharge and how hot the pack gets.
Voltage curve. Lead-acid sags under load and the cart feels slower as the pack drains. Lithium holds voltage much flatter, so the cart feels the same at 20 per cent as at 80.
The parts people forget
This is where conversions go over budget.
The charger. A lead-acid charger uses a bulk-absorption-float profile that does not suit lithium. Many conversions need a lithium-specific charger or one that speaks to the pack's battery management system. Budget for this from the start.
The battery meter. A lead-acid state-of-charge gauge reads voltage, and because lithium voltage stays flat, the gauge becomes useless — it will show full until it suddenly does not. A lithium-aware meter is a small part that prevents a large annoyance.
Cables and terminals. A conversion changes the pack layout, so the existing cable lengths and lug sizes frequently do not fit. Cable kits are cheap; improvising is how resistance and heat problems start.
Hold-downs and trays. A much lighter pack in a compartment built for a heavy one needs proper securing.
Does it fit your cart?
Match the pack voltage to your existing system. Count the batteries first: six 6V is 36V; six 8V, eight 6V or four 12V is 48V. Drop-in packs exist for the common Club Car, EZGO and Yamaha configurations, but "drop-in" usually still assumes you sort the charger and the meter.
On a 36V cart, check whether a 48V conversion is being suggested — that is a bigger job than a battery swap, because the motor and controller also have to cope.
Is it worth it?
The honest answer depends on how you use the cart. If it is a course cart doing a few rounds a week, a good lead-acid set replaced every few years is hard to beat on cost. If the cart is a neighbourhood vehicle doing daily miles, the weight saving, the charge time and the absence of maintenance change the experience enough that most owners who switch do not go back.
What we stock
We carry the conversion-adjacent parts — chargers, receptacles, battery cable kits, meters and hold-down hardware — rather than the lithium packs themselves. If you are planning a conversion, those are the parts to order alongside whichever pack you choose.

Frequently asked questions
What else do I need for a golf cart lithium conversion?
Usually a lithium-compatible charger, a lithium-aware battery meter, and often a new cable kit because the pack layout changes. These are the parts most conversion budgets miss.
Can I use my old charger with lithium batteries?
Often not. Lead-acid chargers use a charge profile that does not suit lithium. Check whether your pack requires a lithium-specific charger.
Why does my battery gauge read wrong after converting?
Lead-acid gauges infer charge from voltage, and lithium voltage stays flat until the pack is nearly empty. You need a lithium-aware meter.
How do I know if my cart is 36V or 48V?
Count the batteries and read the voltage on one. Six 6V is 36V; six 8V, eight 6V or four 12V is 48V.
