    Just wondering does anyone know can you convert cell from a Leaf battery into a solar battery? not the full battery but sections out of it?

    Not quite the answer to your question Shef, but check out new episode of Fully Charged today on PowerVault, a startup using second life cells from Renault for home storage.

    Also, I recall an article about a year ago, I think on Cleantechnica, where some Norwegian dude pulled the modules from a crashed Leaf and stuck them in a server rack his employer was binning! Cost him about 3k for an 18-odd KWh battery!

    19kWh New.


    Is that a 19kWh battery new?

    It's 14 x 6volts, you can bolt together. but you can get much bigger forklift batteries for similar money.

    No, it’s 14 leisure batteries, as used in campervans, etc. That’s a fairly big price differential with Li-ion, but presumably comes with some hefty caveats in space, safety, care, etc.

    Traction motive battery for high torque electric motors found in golf carts & access MEWPs.
    They are safer; they don't spontaneously combust and then keep reigniting under thermal-runaway conditions.

    Leisure batteries are muck.

    My 6volts are 4 years old and good as new in daily use.
    62% SOC today. 15Watt solar incoming powering this post.

    I got offered 5kWh of Leaf batteries for 500 quid..... :-) I am just wondering how I would then hook up to Solar PV.....

    Of course you can, it's a battery, it stores electricity. Whether or not it's worth it will probably depend on how much you'd end up paying for them and what you'd need to charge them properly.

    Friend of mine lives very remote in South Africa and his whole solar array is setup from old submarine batteries. (and no he won't tell anyone how he got to be in possession of submarine batteries but knowing him I'm going to guess there was some wheeling and dealing involved)

    interesting article here :

    Submarine batteries are the same as sealed forklift batteries and old telecoms outposts & UPS.

    Thanks for all the replies but I am even more confused now :-)

    Really? I'd have thought they'd somehow be more exotic.

    Although I guess it kinda makes sense, if I was in a pressurized tube under water I'd prefer old and reliable over exotic too

    I've been using leaf modules for about 4 years now. They're very easy to work with.
    I wouldn't recommend an installation like the one in that video, the parallel packs have no fusing which is very poor practice.

    Can I ask if you’re an electrician/greentech professional? Or is this doable as a relative novice DIY’er? (With electrician’s help of course!)

    It's probably not within the DIY range to be honest unless you are electrically competent at the very least.
    Working with batteries of any description is potentially dangerous, especially once you start combining them in series and parallel strings.
    I'm an engineer and work in the area.

    Im not, at most I can build a home computer and put the components together...I think a step too far
