I have read a lot on here about on board versus portable chargers and what not. Certainly, there are pros and cons to both. I have decided after (as some of you know) fighting with my on board and my cranking battery for some time to go with a Lester or the big MinnKota 4 bank. I am having a hard time figuring out on here what Lester BCB recommends and what set up is recommended for it. So, please do tell. I am running a 36V MK on the standard 4 battery set up.
