If any one wants a Fruzend kit I have an unopened unused original one with the translucent end caps in its green box.
I can post it for £23 inc postage.
Also I have two kits which I have used and now dismantled and chucked together in one box, again if they are of use to anyone then a sensible offer of about £12/15 + p&p will secure the whole box.
Some end caps (10 or so) are cracked /broken out of about 200 so plenty still usable to make up a decent sized battery or two.
New V2 kit on kickstarter $28 for 60 caps enough for 30 cells. Nickel coated copper and copper alloy contacts,nuts and bus bars. 20amp continuous per cell. New polymer fits together easier and longer terminal posts to allow for more bus bars.
