This YakGear 12V 20Ah Vortex Battery was built by taking two 10ah batteries wired in parallel and adding a shock absorbent and waterproof, double neoprene outer shell. Combined with 2 universal connectors, this battery is built for rugged and wet conditions where you need dependable power. Perfect for 12-volt trolling motors up to 35lb thrust, off-grid music systems, or any 12-volt electronics where you need hours of power. Also works great with the Micro Pole micro anchor. Available in Black or Deep Blue. Powered by Dakota Lithium

When selecting the right battery for the ideal solution, you should research the Ah (Ampere Hour) draw on your electronics you are connecting. We have found the following below, which should help some in your choices.
Depth and Fish Finders will typically draw as little as .30 amps per hour and up to 1 amp per hour. This is for a typical 4 inches to 5 inches screen that is black and white or color. (Read your manual to make sure, these are estimates to understand which battery to purchase). Larger screens that are in color 7-inch to 11-inch screens can draw as much as .8 amps per hour to 1.2 amp per hour.
A 7 Ah Lithium battery will power a 5-inch color screen that draws .4 amps per hour for 17 hours or so assuming the battery is charged fully. (Just an estimate)
A 10 Ah Lithium battery will power a 5-inch color screen that draws .4 amps per hour for a max of 25 hours to as little as 10 hours depending on your amp draw (Read your manual to ensure power draw)
Lithium power is different than typical SLA power.
Lithium will offer a constant current up to the battery reaching around 9 volts and then it will shut off. An SLA battery will start to lose power and your electronics will slow down or get dimmer. In some cases, you will try to turn up the brightness when using an SLA and ask for more power which will shorten the battery life as well.
If you are adding additional battery drains, LED lighting or charging your phone or cameras, this will also add to your hourly amperage draw as well. Calculate your amperage draw to select the correct battery for the correct use.
If powering a Micro Pole, please use the 20ah Vortex battery. Other products can be attached to this, but you will minimally need the 20ah Vortex for the Power Pole. Depending on your setting for the surface, your Micro Pole will need a lot of power to push through harder surfaces.
