Best in-line charger for my boat

[Fishbowl836]

I am looking for everyone’s input/feedback on the best in-line charger for my boat. What charger would you recommend and what were the pros and cons’ including everything from cost, installation, speed of charge, and most of all is it still working today. Unit will need to be a two bank charger and will be installed in the front of the boat therefore I will need to run extensions to the starting battery in the back of the boat. Other question is, does the unit get hot and do they need ventilation? My plan is to install the unit in a cabinet area next to the deep cycle battery and then plug it in every night when I come back home and then unplug and go the next morning. Also can you recommend the best place to purchase the unit? In advance, thank you for your time. Is spring coming?:

Love the battery tender in my trophy.

Yea love the one on my Trophy as well. I will. Mine is a Guest Trolling series for 2 batteries. Its great not having to pull the batteries for the winter. I just plug it in all winter. The port side battery is not bad to get out but the starboard side is under the oil tank for the oil injection and a pain to get out.
