Can I just charge the batteries with a simple battery tender charger?

[JMSGA]

Ive got a 22 AR250. I like to keep my batteries on a tender at the house. The battery setup is throwing me for a loop with the BEP setup. Ive read alot of the posts already but am still confused. Can I just charge each of the two batteries individually by unplugging the small ground wire coming off the back of the BEP? Then plug it back in when I get done charging?

That is what I do now, I added a fuse inline to the grounding wire and I just pull the fuse out when I am charging the 2 Batteries at home. I use a 2 bank charger that charges each battery separately. I have my charger always connected so I just need to plug it into 120 line and pull the fuse. You can rewire the ground to go live when the boat is running but I did not want to pull the switches off to get to the back of them etc.

Thanks, I forgot I need a deep cycle charger too.

Depends on the amperage... Most simple battery tenders won't supply enough amperage to fully charge the battery especially on a deep cycle. I would recommend at least 10 amps like this NOCO - 2-Bank 20A On-Board Battery Charger - GENPRO10X2 I have the one bank version but plan on getting this when it comes back in stock. If you run your radio for hours on end at the beach like I do you need this to bring the battery back up.
