Only buy if you know what LiFePO4 is.  Pick-up only from East Auckland, because it is too hard to ship lithium batteries (unless you arrange where I can drop it off).

Our supplier sent us the batteries out of spec., so we have qty 77 that they are offering to staff at a discounted price of $12 each.  It is supposed to be minimum 9.5Ah, but came out as nominally 9Ah.  If there is enough interest then I can get them for you, but if not enough interest then they have to be shipped back to China.  Dimensions are 64mmx133mmx16mm with a 120mm wire out of one corner.  No protection circuit included, who needs it for safe LiFePO4 anyway?  Wires are spec'ed for 5A rating, but the battery can do about 45A if you use appropriate termination.

I have used a few for a while, 8 in series for my 24V EnviroMower and 4 in series for my 12V electric gate.  Mower was a mains charger, gate has a solar charger.  I've got plans to make a 12V DC UPS since my server PC, router, modem, etc. all runs off 12V so I don't see the need for wasting conversion power in a 240V mains UPS.  Balancing is very easy, connect an LED across each cell and then charge to 3.5V per cell (so a 12V pack is charged with a standard 13.8V-14V charger!).

Send me a PM ASAP if interested, I have to know within 1-2 days or it will be too late.  There must be enough interest before I can get them.  Note this is only for home projects, don't want to see these on TradeMe etc.
