Or.... use a lithium battery which doesn’t need to be vented, can be oriented in any direction, and would likely weigh less than the incremental heavy gauge cabling run required by the windlass.... connection to the charger could be much smaller depending on the expected charging rate, and dod is greater, requiring a lower a/h rated (smaller) battery for the equivalent usable capacity.
Charge via a small dc:dc charger off the house system. https://ca.renogy.com/renogy-12v-dc-to-dc-on-board-battery-charger/?gclid=Cj0KCQjwi7yCBhDJARIsAMWFScNT2ifqnsnfIeF-stcBCY7Z0uqGfL40x2HY83wccuRItirzuy_Ap_QaAhnoEALw_wcB Dave 33-2 Sent from my iPhone > On Mar 15, 2021, at 9:13 PM, Dave Godwin via CnC-List <cnc-list@cnc-list.com> > wrote: > > > Pete, > > Since I’m not on the criteria list of having mounted a battery for the > windless in the bow/v-berth area on our 1982 37’ I thought I’d weigh in > anyway.
