30w panel enough to keep an 8D battery charged?

[matt86m]

I have 3 - 1 starting and 2 chassis 8D batteries on my moho. Looking at a 30w panel kit on Amazon. Im just looking to keep the battery from dying in between long periods on non-use. (Yes, I know, use the damn thing!!!!!)

Opinions? There are 10, 20, 30, 50 & 100w panels avail with the controller and wiring available.

I have 30s on my MOHO and Box Trailer. The box trailer (one 12v ATV battery) does great, no issues always enough charge for lights etc... but the MoHo (2x6v golf cart) doesn't keep well and sometimes even boils the batteries. I never flip the master switch to OFF so there is always some load Green lights, controls, etc....
