Custom Lightweight 12V 18Ah LiFePO4 Lithium Electric Golf Cart Battery Pack

Designed as a premium replacement for traditional lead-acid batteries, the 12V 18Ah LiFePO4 (Lithium Iron Phosphate) Battery delivers unmatched safety, longevity, and performance for a wide range of applications. With a nominal voltage of 12.8V (full charge 14.6V) and 18Ah capacity (230.4Wh energy), this battery merges LiFePO4’s inherent stability with a compact, maintenance-free design—making it the ideal power source for RVs, marine equipment, security systems, outdoor gear, and backup power setups.

Say goodbye to the limitations of lead-acid batteries and embrace the future of rechargeable power:

• Inherent Safety You Can Trust: LiFePO4 chemistry eliminates risks of thermal runaway, fire, or explosion—even during overcharging, short circuits, or physical impact. Unlike lead-acid batteries that leak toxic acid or Li-ion batteries prone to overheating, this battery features a stable crystal structure that ensures safe operation in any environment, from indoor backup systems to outdoor camping gear.
• 3X Longer Cycle Life: Enjoy 4,000+ deep charge-discharge cycles (retaining 80% capacity), compared to just 300-500 cycles for lead-acid alternatives. This means the battery lasts 5-10 years with regular use, reducing replacement costs and environmental waste.
• Lightweight & Compact: Weighing only 1.8kg (4 lbs)—a third of the weight of lead-acid equivalents (10-15kg)—it’s easy to install and transport. Its compact dimensions (177 x 167 x 124 mm) fit seamlessly into standard battery compartments, no modifications needed.
• No Maintenance Required: Unlike lead-acid batteries that need water refilling, terminal cleaning, or acid level checks, this LiFePO4 battery is fully sealed and maintenance-free. Simply install it and enjoy reliable power for years.
• No Memory Effect & Low Self-Discharge: Partial charging won’t reduce capacity—top it up anytime without worrying about performance loss. A self-discharge rate of <3% per month preserves energy during storage, so it’s ready to use even after months of inactivity (ideal for seasonal gear like RVs or camping equipment).
