    I use a 8AH Zippy brand lipo in my cruiser. Hobby King carries a wide selection of differently shaped batteries that you can use.

    I bought many of the Zippy LifePO4 from Hobby King as did Ted. Ted's puffed up before they were even used... I think they are not making as much and the quality is lower.. all my zippy packs puffed up and eventually died. I have a set of drone lipo I got over a year ago and look great. Results may vary.

    I'm looking at a zeee shorty 4200mah lipo for $30.
    It would take up less space in my cruisers.

    Does the "c" rating mean anything to us?

    "C" Rating is significant to us,, C Rating is an indicator of the continuous discharge rate of a LiPo. It allows us to calculate the maximum constant current you can draw from the LiPo pack safely without harming the battery. For example, if you have a 3S 1000mah 20C LiPo pack, your safe max current draw would be 1000ma x 20C = 20A.

    Good explanation here:

    C rating applies to any battery, not just LiPos.

    Higher C rating is generally better but only to a point, the difference between being able to source 150A vs 300A in a typical boat is small enough to be meaningless. (Realistically you aren't going to be drawing anywhere near that current and if you tried to something else would probably pop) Higher C rating tends to cost more too.
