12.8V 5Ah (64Wh) LiFePO4 Deep Cycle Battery

A lighter, longer-lasting drop-in replacement for your 12V SLA battery.

This Mach 1 12.8V 5Ah LiFePO4 battery delivers reliable, maintenance-free power for solar setups, RVs, fish finders, deer feeders, ham radios, garage door systems, and backup power applications. Built with lithium iron phosphate cells, it offers a longer lifespan and lighter weight than traditional sealed lead acid batteries, with no modification needed for a direct swap.

Key Features

• Advanced LiFePO4 chemistry — improved efficiency, thermal stability, and long-term reliability over standard lithium-ion
• 8-10x longer cycle life than SLA batteries — a more cost-effective long-term energy solution
• Lighter weight, higher energy density — more usable power without the bulk of lead acid batteries
• Drop-in SLA replacement — compatible with most 12V systems, no modification required
• Built-in BMS protection — guards against overcharge, over-discharge, overcurrent, and short-circuit
• Maintenance-free and eco-friendly — no acid, no toxic metals, no upkeep required
• Stable performance in hot and cold weather — reliable indoors or outdoors, year-round

Ideal For

Deer feeders, ham radios, garage door openers, alarm systems, camping setups, solar systems, RVs, and fish finders.

Compatibility
