    I am new here so had a few questions on a battery pack that I have that needs the batteries replaced. The battery pack has 2 6v 12ah batteries inside in series with some sort of electronic device attaching the positive and negative terminals together on one end, what is this? Secondly, could I just use 1 12v 12ah battery instead of linking 2 6v together? Thoughts?

    Thanks in advance for your help.

    If you replace it with a single 12V battery, wire a fuse of a similar rating in series with it.

    Thanks

    What is written on it?

    Edit: ah, it's a polyfuse. Just desolder it and reuse it.

    Is there any advantage to the two 6v batteries over one 12v?

    Thanks

    They provide a handy place to connect that polyfuse. Aside from that, not much.

    Ha! Well sounds as if I can fix this $800 battery pack for less than $20 then,(just a little bit of mark up) I appreciate all the help!
