    I'm building a 1/144 fast gun Lutzow. It is a 12v system. I am not sure what kind of batteries to get for it or aH capacity. Any suggestions?

    Does it need to be 12V?
    If not, I would crank up the voltage to reduce the amps. Should run cooler and longer.

    direct answer…

    you can try to calc’d it based on motors and which format you will play.

    …but I always took this approach.. how much can you afford and how much can you fit in your hull?

    Which Lutzow? The Derfflinger class or the renamed Deutschland?

    The ww2 Lutzow. The Deutcshland that was sold off to russia.

    My motor's upper limit is 12v. I would like to keep it around there.

    12v is good, amp draw on motors for cruiser is not a concern, I use 3s LiPos in my Lutzow, somewhere around 5000 to 6000 mAh, many guys have used goldbat brand from Amazon with success. 1 battery on board, should last 2 sorties with between 50% to 75% discharge, can also replace every sortie if desired

    here is link for example, they have several close variations

    Thanks for the link.

    Also, my pump is brushed and my drives are brushless with each type of ESC respectively. Would these type of batteries cause issues with that? Or issues for the batteries?

    No, the batteries will do fine with that setup

    I don't know why the ones with XT60 connectors are a few dollars more expensive, but here's the same thing with XT60's. I use these in my convoys. You should easily fit two of them side-by-side in the Lutzow, with a CO2 bottle in between. For our local battles, 5200mAh x2 (in parallel) will be plenty for several sorties, possibly for the whole day depending on how much you pump. Definitely worth standardizing on a single connector within the club, though. All of my ships use XT60's.
