Hello, All. Long time lurker, first time poster.
I have a 2018 Nissan NV200 that I have converted. I rely mainly on shore power for all electrical needs, but I did run a 1.5ah Ventair exhaust fan straight to the van’s fuse box. Do any of you have a recommendation for maintaining the starter battery while running the fan? I would prefer something that I can plug in, rather than solar. TIA
