My battery is previously connected in the app, but now it says disconnected.
Asked by Dominic R. in Delaware
ODIN
TECH GOD!Official AnswerPlease attempt to fully close the Norsk Guardian app. This can be done on iPhone by swiping up from the bottom of your screen until your app tabs pop up, simply swipe upwards on the app tab, and then re-launch the Norsk Guardian App. This can be done on Android by clicking the three vertical lines on the bottom left of your home-screen and swiping the Norsk Guardian App upwards.
If this does not work, delete the battery from your app, and attempt to re-add the battery.
If both previous steps do not work, delete the Norsk Guardian app and re-install.

What is the correct charger for my Norsk 11.1V portable sonar battery?
Asked by Allison M. in South Carolina
ODIN
TECH GOD!Official AnswerFor our Gen-1 and Gen-2 11.1v portable sonar batteries you cannot use the 14.2v 3a Green charger. This is because the previous generations used to be Lithium-Ion, but now our Gen-3 is LiFePO4, we do offer a 2a 12.6v Lithium-Ion battery made specifically for your Gen-1 and Gen-2 11.1v portable sonar batteries.

Can I extend the charging leads on my Evo-Tec On-Board Charger?
Asked by Jeffrey A. in West Virginia
ODIN
TECH GOD!Official AnswerWe suggest you avoid extending the charging leads of your Evo-Tec On-Board Charger if possible. Doing so may cause undesirable performance, excessive heat generation due to the increased resistance caused by the longer leads and may significantly shorten your charger’s lifespan.
If your install must have the charging leads extended, please be sure to review our wire gauge chart to ensure the correct gauge wire is used to prevent performance issues & excessive heat generation when charging. Using undersized wire could lead to damage and this would not be covered by the warranty.
Our wire size guide can be found here.
