$45.00The Story
Overview
The Summit Lithium 20Ah NMC Battery is built for lighter forward-facing sonar setups and portable ice electronics that need solid runtime without extra weight. This battery delivers stable 14.8V power, zero voltage sag, and dependable cold-weather performance in a compact footprint. Perfect for fishermen running smaller screens or minimal shuttle loads who want a lighter pack that still holds up during long days on the ice.
Lithium NMC batteries are the superior choice for portable electronics:
NMC maintains higher voltage under load.
NMC Performs better in cold climates, especially below 32°F.
LiFePO₄ has reduced power output and charging restrictions in the cold.
Industry leading Battery Management Platform
Core Features:
Real-Time Performance Monitoring
State of Charge (SOC) accuracy to 99.5%
Individual cell voltage tracking (±0.01V)
Multi-zone temperature profiling
Advanced Protection Systems
Instantaneous over/under voltage response
Microsecond short-circuit interruption
Multi-point thermal management
Active Cell Balancing
Continuous voltage synchronization
Prevention of cell degradation during cycles
Enhanced energy preservation
Key Features:
Cold-weather ready — holds voltage in freezing temps
Stable 14.8V output for clean sonar returns
Zero drop-outs even when the screen brightness is cranked
Lightweight — only 2.98 lbs
Designed for portable sonar shuttles
NMC chemistry for high energy density
Fast charging with included 6A charger
SAE quick-connect harness included
Safe, protected power with integrated BMS
Ideal For:
Fits best inside the Summit Shuttle but is compatible with most popular brands. Summit Fishing, HD Innovations, ArcLab, Fin Gear, Fish Armor, Ice Master Fishing, TKI, BassKhang, Vexilar, etc.
Smaller FFS bundles (7–9")
Lightweight pack builds
Anglers who move often and want to keep weight down
Backup power for longer trips
