I don’t think you will have a problem, as lithium batteries never drop their output voltage till about 10-15% left in the battery. Mine gives a constant 13.3 volts of output according to my phone app on the Ionic batteries. If running a 12 volt trolling motor, you could always get a 20 or 30 amp battery to hook in parallel to add more user amps if needed. That 60 amp battery will actually charge up to a total amps of 62 to maybe 64 amps topped off when fully charged due to the construction of the amount of lithium cells they use when building it. If ever adding lithium batteries in parallel and they are not the same size just make sure they are of the same make (Manufacturer) as the BMS system built into each battery works together when charging and using. I have paralleled before for 12 volt usage, a 100, a 50 amp and a 30 amp before for a total of 197 amps and 7 hrs of hard trolling running crankbaits in a 10’-15 mph wind in a 2’ chop only using maybe 15% total amps just to see how the BMS system works and to see how many amps I would use running a 12 volt V2 Power Drive on a 1648 jon boat. Each battery when built, has a couple more amps than advertised when built.
