To date I have had no battery issues spending one night away from the dock, but I would like to start taking longer such trips. After reading many of the related postings here and from Jon Vez on the 355 forum I plan to wire my two stock batteries into a single bank. When they die I'll likely replace them with 6volt batteries. Rather than install a new battery as a reserve/emergency I'm considering a small litthium battery charger such as the Weego 44. I would just have to remember to recharge the Wedge once a month. Does anyone have experience with this type charger?
