Vexilar 12V Lithium Ion Battery

The Vexilar 12V Lithium Ion Battery (Model V-100L) is a purpose-built 9.6 amp-hour lithium power cell engineered as a direct replacement for standard Vexilar flasher and pack batteries. This 12-volt lithium battery leverages LiFePO4 chemistry to deliver extended runtime and cycle longevity compared to traditional sealed lead-acid batteries, while maintaining full compatibility with the 1-amp fully-automatic Vexilar battery charger.

At 2.95 pounds, this lithium ion battery weighs approximately half that of equivalent SLA units, reducing overall pack weight without sacrificing capacity or output. The LiFePO4 chemistry delivers roughly twice the recharge cycles of lead-acid alternatives, translating to significantly lower cost-per-cycle over the battery's service life. The compact footprint (4 x 3 x 7 inches) fits seamlessly into existing Vexilar equipment mounting points, eliminating the need for custom modifications or adapter harnesses. Output remains stable across discharge cycles, maintaining consistent voltage delivery to electronics even as remaining charge depletes.

This battery is built for users operating Vexilar ice-fishing flashers, pack systems, and related electronics in demanding field conditions. The weight reduction makes repeated pack transitions more practical during extended fishing operations, while the extended cycle life justifies the upfront investment for serious anglers who deploy their equipment seasonally or year-round. Drop-in compatibility eliminates compatibility uncertainty—it functions as a straightforward swap with no electrical configuration changes required.

The lithium ion advantage has become standard in professional portable electronics. This Vexilar battery brings that proven technology to flasher systems, offering operators a meaningful performance upgrade within their existing equipment ecosystem without requiring new chargers or substantial learning curves.
