    Default Garmin Livescope the battery eater

    My group 24, 18 month old, high dollar Maintenence free Deka cranking battery did fine running 2 Helix Mega’s but one Helix and the Livescope is just too much for it. Running it for 3-4 hours is pulling the battery down to the point that the motor is noticeably turning over slowly while cranking. It’s jidt a matter of time til I have to use my jumper cables to get going. I charge my batteries after every trip with my onboard MK charger.

    With the deep drain these new electronics pull on the battery I wonder if a “dual purpose” battery would be a better choice than a standard cranking battery? I know very little about the DP batteries but I know that cranking batteries aren’t made to be discharged often like happens now with the LS.

    Thoughts?

    You need to have that battery load tested.

    I am currently using a jet ski battery that was given me to power my Live Scope System. I placed the battery on charger overnight before using it. I have used it on four different days now without needing to recharge it. Probably around 20 total hours of use during these four days I have used it.

    I've seen videos that say the lithium battery is good for 10 hours of continuous use with the Live Scope System. So I suspect a problem with your boat battery.

    Hmmmm. I have a load tester at the shop. I’ll check it.

    Buy a second battery and use it specifically for the livescope. Iíve been using separate batteries on my electronics up front for years now. No more problems with my cranking battery. Well worth the peace of mind of not worrying about being stranded because of a weak battery.

    Same here, more electronics draw more power, get a second battery and go way larger than series 24. Check and see how many amps your motor needs to start with and you can maybe just downsize to a 450 amp or 550 amp starting battery for the motor. Starting battery will weigh way less than a deep cycle.

    Only problem for me with going with a separate battery would be needing an additional charger. I have considered buying another battery identical to the one that I have, as long as my current battery tests good and wiring them in parallel to double the amp hours. I could charge both with one leg from my onboard charger

    Takes double the time to use one leg of a dual charger charging 2 batteries in series. Just use any charger to charge the motor battery and once it’s charged, it doesn’t loose that charge as nothing from motor is trickling usage from it. I use a minn Kota 10 amp portable charger 110PD on motor battery and it’s a awesome portable charger that will also minimize the battery as it charges just like on board chargers. Search the web for best prices.

    I suspect you have an issue also FurFlyin. I have been shutting down my 10 inch Lowrance console finder while I use my LS up front. Since I started doing that I barely draw any power out of my batteries anymore. I can sit up front with LS all day and barely use any power at all. You may possibly have some issue that is causing both the draining problem and your interference problem.
