The best battery for Livescope depends on the amount of time you wish to spend on the water with full power. Lithium-Ion is a must with modern tech. If you’re using it for ice fishing, you definitely want the weight and size convenience. In my opinion, a 12 V, 23 Ah Lithium Ion battery doesn’t cut it. Maybe on board a yak, but that would be it. You want a minimum of 8 hours run time at full power, without having to manage draw by reducing screen brightness and turning off functions. A dedicated 46 Ah Lithium-Ion battery is a great starting point. But it will all depend on your circumstances and general power requirements.
