Vexilar 12V Lithium Ion Battery & Charger

The Vexilar 12V Lithium Ion Battery & Charger (model V-120L) is purpose-built for operators and anglers who demand extended runtime and reliable power in the field. This 12-volt, 9 amp-hour lithium battery system replaces legacy Vexilar Flasher and Pack batteries while maintaining full compatibility with the manufacturer's standard 1-amp automatic charger. Whether deployed for tactical sonar operations, emergency response, or extended off-grid missions, this battery pack delivers consistent performance in demanding environments where dependable power is non-negotiable.

Lithium ion chemistry offers critical advantages over traditional lead-acid alternatives: superior energy density, negligible self-discharge, and significantly reduced weight at just 3.35 pounds. The compact footprint—measuring 6 x 3 x 7 inches—fits seamlessly into tactical packs, vehicle mounts, or portable ice-fishing rigs without sacrificing amp-hour capacity. The fully-automatic 1-amp charger optimizes cell longevity by managing charge rates intelligently, eliminating overcharge risk while maintaining quick turnaround between operations. This intelligent charging ecosystem ensures the battery reaches peak performance while extending service life across hundreds of charge cycles.

Field operators and first responders benefit most from this upgrade, particularly those relying on Vexilar Flasher units for sonar detection, navigation, or underwater reconnaissance. Drop-in compatibility eliminates the need for adapter harnesses or rewiring—simply remove the old battery pack and install the V-120L without any modifications to existing equipment. The integrated battery management system safeguards against thermal runaway and short-circuit conditions, critical features for operators working in remote locations where equipment failure creates unacceptable risk. For anyone currently using Vexilar sonar systems or portable electronic platforms, this lithium solution provides measurably superior runtime and reliability compared to original equipment batteries.
