@Kurosawa Hope you're enjoying Cruise Moab! I was curious about your experience with the Deka main battery upgrade. I'm expecting my Trekbox in the next 2 months and I'm planning for all the bits and bobs I'll want to put in during that install. I am considering a LiFEPO4 battery under one of the wings. However, until that miraculous day happens, I think the Deka main battery upgrade might be "the way". I'm thinking it would still be a good upgrade as the long-term goal is winch and lighting off the main battery. I was hoping for some honest feedback on the mod. Thank you!
