Lithium battery conversion
Find a provider to convert a lead-acid cart to lithium — including the charger, BMS, mounting and wiring work the batteries alone do not cover.
What this covers
- Assessing whether your cart and controller suit a lithium pack at all
- Pack and BMS selection
- A charger matched to the BMS — a lead-acid charger is generally not appropriate
- Tray, bracket and hold-down adaptation so nothing can move
- Cable sizing and fusing reviewed against the new pack
- Commissioning and testing before the cart is handed back
Symptoms that lead here
- You are replacing a tired lead-acid pack and weighing the options
- You want faster charging or more usable range
- You want the weight out of the cart
- You are tired of watering flooded batteries
What a provider is likely to check
- Controller voltage tolerance against the pack's real operating range
- Physical fit, and what the tray needs to restrain a much smaller pack
- Existing cable sizing and fuse ratings
- How the cart is used, since short occasional trips rarely justify the price difference
- Warranty and community or insurance implications
This describes how the work is usually approached. It is not a specification of what any individual provider will do — agree the scope with them directly.
Mobile or shop?
Mobile
Some experienced mobile providers do conversions on site, but many do not.
Shop
Usually shop work. It involves mechanical adaptation, electrical review and a commissioning step.
What to have ready
Having these to hand makes the first conversation shorter and usually cheaper.
- Make, model, year and current pack voltage
- Controller make and model if you know it
- How you actually use the cart — distance, terrain, load, frequency
- Whether the existing charger is on-board or portable
- Any community rules about modified vehicles
Safety first
Lithium cells store a great deal of energy in a small package. A short circuit during installation can deliver hundreds of amps. Incorrect BMS configuration, an unsuitable charger, mechanical damage during fitting, or a pack that is not properly restrained can all lead to thermal runaway — a fire that is difficult to extinguish and produces toxic smoke. We do not publish a step-by-step conversion procedure for this reason.
Work it out yourself first
You will get a better answer from a provider if you can describe the fault precisely. These guides help you do that — and some of them will save you the call entirely.
- Lead-acid or lithium: what a conversion actually involvesAn honest comparison of the two pack types and a realistic account of what a lithium conversion requires beyond the batteries themselves.
- Electric golf cart won't chargeWork through the most common reasons a charger won't start or won't finish, from the wall outlet to the pack itself — and know when to stop and call a professional.
