I keep hearing about people going to Lithium Batteries for Garmin Livescope , Some buying drill batteries , and docking station to plug battery in and a charger . The batteries are low amp hours and some guys carry two .
I figured the cost and went with a AMPED battery with 32 amp hours and runs 14 volts and should not drop below 12 volts. Lithum is light , this one weighs 4.8 lbs and comes with a charger. They suppose to charge real fast and this should run my Garmin 1242xsv , black box for transducer for two or more days . No need for a docking station or multiple batteries . It came in today , just need to change conectors on my wiring and see how it works .
Lithium Batteries are pricey but small and light . This one was 250 shipped no tax or shipping .
