Golf Cart Batteries. Delivered & Installed.
We come to you — home, community, or course. Serving the entire Phoenix Valley.
Included with Every Installation
FREE 4-Gauge Cable Upgrade — Every Installation
Every battery installation includes a free upgrade to heavy-duty 4-gauge cables. Thicker cables mean less resistance, cooler operation, and longer battery life. Most shops charge extra. We include it because it's the right way to do the job.
How We Do Business
We Do Not Haul Away Your Golf Cart Like the Other Guys Do.
No trip fee. No hauling. No shop drop-off.
Every other company charges a trip fee just to come look at your cart — and most of them want to haul it away to their shop on top of that. We come to your home, your community, or your course and do the entire job on the spot. No trip fee, ever. Your cart never leaves your property.
The price we quote is the price you pay.
You know how it goes — you take your vehicle in for one thing and they call you with a list of "while we're in there" extras. We don't do that. We quote you a flat price upfront. No surprise charges, no add-ons, no pressure.
We'll tell you if you don't need new batteries yet.
Some people in this business will sell you batteries you don't need. We've been doing this 16 years and we're still here because we're honest. If your batteries have life left in them, we'll tell you — and we'll tell you what to watch for so you know when the time actually comes.
Not Sure What You Have?
How to Identify My Battery
36V or 48V? Six batteries or four? It matters — and it's easier to figure out than you think. We've put together a simple guide that shows you exactly how to identify your golf cart's battery system before you call.

Our lead acid batteries come with a full 3-year warranty (12-volt batteries carry a 2-year warranty). We carry Rocket brand batteries.
Volta Power Lithium
Best in ClassOur proprietary Volta Power Lithium batteries carry an 8-year warranty. No one else in the golf cart battery space comes close.
Introducing Volta Power Lithium
Our Battery. Our Brand. Our Warranty.
Volta Power Lithium is a brand we designed and own. These aren't off-the-shelf batteries with our name on them — they're engineered from the ground up for golf cart performance in the Arizona heat. Lighter, longer-lasting, and backed by an 8-year warranty that's the best in the business.
Learn About Volta Power Lithium
What's Inside Every Volta Power Lithium Battery
Most lithium batteries are built to a price. Ours are built to a standard. Here's what makes Volta Power different from everything else on the market.
250-Amp BMS — 67% More Protection
Every Volta Power battery includes a 250-amp Battery Management System (BMS). The BMS is the brain of the battery — it monitors voltage, temperature, and current to protect the cells from overcharge, over-discharge, and short circuits. The industry standard is 150 amps. Ours is 250. That extra headroom means your battery handles heavy loads, steep hills, and hot Arizona days without breaking a sweat.
Built-In Active Cell Balancer
Lithium batteries are made up of individual cells wired together. Over time, those cells drift out of balance — some charge faster, some drain faster. An unbalanced pack loses capacity, runs hot, and wears out early. Passive balancers (what most batteries use) just bleed off excess charge from the stronger cells and waste it as heat. Our active balancer is smarter: it actually moves energy from stronger cells to weaker ones, keeping the whole pack in sync. The result is more usable capacity, longer cycle life, and a battery that performs like new for years longer.
Built-In Fire Suppressant
We are the only golf cart lithium battery company with a built-in fire suppressant system. Lithium batteries can experience thermal runaway — a chain reaction where one overheated cell triggers the next. Our fire suppressant is integrated directly into the battery housing and activates automatically if temperatures reach a critical threshold. No other manufacturer in our space offers this. It's not a feature we added — it's a commitment to the safety of our customers and their homes.
Solid Copper Bus Bars — Not Cables
About 90% of lithium battery manufacturers connect their internal cells with cables. Cables flex, corrode, and develop resistance over time — especially in the heat. We use solid copper bus bars instead. Bus bars are rigid, flat copper connectors that deliver a cleaner, lower-resistance connection between cells. Less resistance means less heat, more efficient power transfer, and a longer-lasting battery. It's a more expensive way to build a battery. It's also the right way.
