Emergency Start Reserve – Built-In Backup Power
Think of Emergency Start Reserve (ESR) as a jump-start pack built into your starting battery.
Every Norsk Lithium Starting Battery automatically locks a portion of capacity in reserve—so even after a long day running electronics, livewells and accessories, you still have power ready to crank your outboard:
- ESR is included in every Norsk Lithium starting battery
- 25% of the battery’s capacity is held in reserve and available on demand
- Activate ESR via the Power Management button on top of the battery
- Or trigger ESR through the Norsk Guardian® App for app-based control
With ESR, you can push your day on the water further while having a safety net ready whenever it is time to head back to the ramp.
Advanced Protection with Voltage Transient Suppression (VTS)
Modern outboards and multi-screen electronics are a serious investment. Voltage Transient Suppression (VTS) helps protect that investment if the battery’s internal BMS ever has to disconnect while the engine’s charging system is still active.
- Standard on all Norsk Lithium starting batteries
- Continuously works in the background to absorb and suppress harmful voltage spikes
- Helps protect your outboard’s charging system and connected accessories
- Acts as a guard against electrical surges if the BMS disconnects under charge
With VTS, you can run hard and power multiple accessories with confidence, knowing your gear is protected from transient voltage events.
Built for Modern Boats and Serious Boaters
Norsk Lithium Starting Batteries with Guardian Technology are ideal for:
- Outboard-powered bass boats, walleye rigs and multi-species boats
- Electronics-heavy setups with multiple graphs, forward-facing sonar and pumps
