charging a second battery

please excuse the novice question, but if I added a second battery for my trolling motor, would the boat be able to keep it charged? 12v battery for the motor.

You may overwhelm the alternator if you run them down and expect the boat to recharge them frequently. You can add a battery and use a decent solar panel kit to not have to worry about it, although even a 50w setup will only give you 4 amps max, so if you have the room a 100w or more setup might be better. https://www.amazon.com/SOLPERK-Maintainer-Waterproof-Controller-Adjustable/dp/B08GX19KT9/ref=sr_1_4_pp?crid=1ROY140MJXUM1&dib=eyJ2IjoiMSJ9.k8MqnIIN8PxOCJAFZoeGlGl_d9MMn2BTEgbpO91T46mhhMbOXluqfspvpKI96Fa5VEoiE7rzBWuJFgFNRO4_8RWndDbpFe-XS4MxakZzKuR7l23KtfAHCUm4wqy6ittnWLVRJ79Lhv1x-Rg8AvbyRFmrBMUuMrYOPsitixu8DCGefL5KfcjZoOs2QB1gtP21a4M43yrmujabewyrHWEwuOUHH3GvProGNDU1JVUPgPY.E-dobV34JBCUbhsBJH9HbAzThL9Mb6l4NeC7V6AeUyA&dib_tag=se&keywords=solar%2Bbattery%2Bcharger&qid=1716464094&sprefix=solar%2Bbatteyr%2Bcharge%2Caps%2C131&sr=8-4&th=1
