Lithium battery upgrades: what you need to know

If you're still running lead-acid batteries in your golf cart, you've probably heard the pitch: "Switch to lithium — it'll change your life." And honestly? It's mostly true. But there are things to know before you pull the trigger.

The benefits that actually matter

• Consistent power. Lead-acid batteries lose voltage as they drain, so your cart gets slower throughout the day. Lithium delivers full power until it's nearly empty.
• Weight savings = better ride. Dropping 250+ pounds of battery weight improves acceleration, braking, handling, and reduces wear on suspension and tires.
• No more watering batteries. Forget the distilled water, the corrosion, the acid spills. Lithium is sealed and maintenance-free.
• Longer range per charge. Most lithium setups deliver 30-50+ miles per charge vs 15-25 for lead-acid.

Common mistakes to avoid

• Buying cheap, no-name lithium packs. Not all lithium batteries are created equal. Cheap cells can be dangerous and may not come with a real warranty. Stick with reputable manufacturers.
• Not upgrading the charger. Lithium batteries need a lithium-compatible charger. Using your old lead-acid charger can damage the cells or create a safety hazard.
• Ignoring the BMS. A quality Battery Management System (BMS) protects against overcharging, over-discharging, and overheating. If the pack doesn't have one, walk away.
• DIY installation without experience. High-voltage lithium systems are not a weekend project. Have a qualified technician handle the install.

Why we include lithium standard

Every new cart we sell at Hawg's — whether it's a Teko, Denago EV, Active EV, or Club Car — comes with a lithium battery system and a manufacturer warranty that covers it. We don't sell lead-acid carts because we don't think they're the right choice for our customers in 2026.
