You could link it with another battery in parallel and it would do the job you are talking about, but the question is why are you having to do that. Be carefull with all of your expensive electronics. They are volt sensitive and can have problems if constantly run under low voltage. IT does seem odd to me that your Cranker cant handle the load your talking about. My cranker serves as a 3rd Troller, runs 2 color units, and a radio without issue. If you are running a wet cell battery for your Cranker maybe you should consider upgrading that to a bigger AGM type. These are doing great in that application and its what BCB recommends. I know this wasnt much help but some others will be around shortly to give you a more educated answer. Chris Coupel Paulina, La.Chris CoupelPaulina, La.
