I know I’ve seen post on here but can’t seem to find it! My starting battery which also powers a new 10 and 12 helix mega wont let both run for very long with out powering them down. Question is what reserve capacity on battery do I need? If u could recommend a battery it would be great !

You need a bigger battery....go up in group size....what group size are you using now ? Mine had a group 24 and I replaced it with a group 29.

Pontoon, I had a similar problem. Turned out to be a bad 'Cell' in the battery, so I guessing you need to replace the battery. The electronics SHOULD not drain your battery unless they are on for a LONG time, like 24 hours. Just my thoughts.
Sam's Club has the Duracell Ultra Platinum AGM group 31 Marine battery on sale $154 each. I just bought 3 for my new boat: 2 for my new 24V MK Terrova and 1 for everything else. Good batteries. No affiliation.
I had similar issues went up a battery size to group 27 seems to be problem solved
