Limitless Lithium SAY7-6AH

Ultra-Lightweight Motorcycle & Powersports Lithium Power

The Limitless Lithium SAY7-6AH is a compact, high-performance LiFePO4 lithium battery designed specifically for motorcycle and powersports applications where weight, space, and starting power matter.

Weighing only 2.1 lbs, the SAY7-6AH delivers an impressive 600 cranking amps, 1,000 watts of continuous power, and up to 1,500 watts of burst power.

With a built-in Battery Management System (BMS), internal cell balancing, and Shake & Wake automatic-start technology, this little battery packs serious performance into an incredibly lightweight package.

POWER & PERFORMANCE

The SAY7-6AH delivers impressive current capability despite its compact size.

Continuous Power: 1,000 Watts
Burst Power: Up to 1,500 Watts
Continuous Discharge Current: 80A
Maximum Burst Discharge: 120A
Cranking Amps: 600A

For motorcycles and powersports applications where every pound counts, the SAY7-6AH provides strong starting and electrical performance without the weight of a traditional battery.

BUILT-IN BMS PROTECTION

The SAY7-6AH features an integrated Battery Management System (BMS) designed to help protect the battery during operation.

The BMS includes a minimum-discharge cutoff of approximately 11.5V–12.2V depending on State of Charge (SOC) and reserves approximately 20% SOC for restarting.

It also features an internal cell-balancing electronic circuit board to help maintain proper cell performance.

SHAKE & WAKE TECHNOLOGY

The SAY7-6AH features Shake & Wake automatic-start technology, designed to help prepare the battery for starting when needed.

Combined with its 600A cranking capability, this provides strong starting performance from a battery weighing just over two pounds.
