It's a bad idea to buy batteries from either ebay or amazon as they are awash with fakes. I can't recommend a NZ supplier as I don't know any. You could buy them from fasttech.com, but it's in China so there will be a wait.

As to which batteries, up to 100 watts I would recommend the LG HG2, Samsung 25R or the 30Q or one of the 20 amp cells listed below. If you intend to use the full 150W then you will probably need a 30 amp cell to be safe.

Try to find a reputable source locally if you can. Then just follow Sonic's suggestion's for good battery selection. Amazon and such are not always cheaper and you may get inferior products.

if ebay really is your only option then go for Samsung 30Q or 25Rs as they are "less" counterfeited (haven't heard of any fakes for those).
