Series 31 wet cell batteries can weigh up to 75 lbs each. 60 amp amped lithium batteries weigh 13.7 lbs each and cost 370.00 each. You can get up to 2 days continuous trolling most times unless in a heavy wind all day with a 12 or 24 volt trolling motor without charging. I get 3 days or more with my 100 amp batteries continuous trolling crankbaits with a 12 v powerdrive trolling motor without charging and most times have still 40% left in them before charging. I use Ionic Lithium batteries that have a Bluetooth phone app for monitoring my battery usage. Solar panels have continuously been discussed before,,and on bbc forum and there is no perfect workable solution in using solar panels due to expense, size of the panels you would need, wattage output, slowness of charging, and having to have continuous sunlight.
