[QUOTE="MrGiggles, post: 481117, member: 22613"] You might consider Valence batteries, salvaged from medical equipment. Pretty cheap in comparison, guys seem to have pretty good luck with them, using them in campers, solar setups, big boats, etc. Since you want the batteries to be easily removable, using a heavy duty plug like this would be preferable instead of fooling with the battery terminals every time. https://www.wiringproducts.com/50-amp-high-power-connectors Your trolling motor battery guage will still work, but it will not be accurate since lithiums have a much smaller operating voltage range. You might consider a separate battery monitor, however many of the higher end lithium batteries already include expandable BMS, some even have bluetooth which allows you to view battery status through your phone. Separate monitors are pretty cheap though. https://www.ebay.com/itm/Battery-Monitor-80V-100A-Caravan-RV-Motorhome-UPS-lithium-iron-lead-acid-999-AH/184345745897?epid=6016586700&hash=item2aebdcd9e9:g:2dUAAOSw89lcozJm [/QUOTE]
