    Default Which Battery Charger and to which Battery?

    Just got a 200 hour 2002 LSV and I am going to install;
    1. a second "House" battery - Group 27 or Group 31 depending on the enclosure I can get and physical size
    2. Blue Seas ACR -- Which One?
    3. Should I change to a larger altenator?
    4. Which onboard charger? C-Tek or ProSport 20?
      1. Which battery do I hook the charger up to? House? Starting? Both?
      2. Can a ProSport 20 be used as a battery tender/maintainer for long periods of time?

    Thanks for any help, Eric (starting to feel like a pro around here with 3 posts already!)

    I think most people go with the ProSport 12, though I don't have one so take that for what it's worth.

    Regarding #3, what alternator is in your 2002 LSV now? In the 2005 model year that I have, the 310 and 325 HP engines had a 70-something Amp alternator, while the 340 had a 90A model. If you already have something around a 90A model, you probably have "lots", as opposed to "adequate only for original configuration".
