Nothing quite as exotic as some but here is the new home of the new 1000amp-hr bank I acquired recently.
Starting from a flatpack iron kitset, lots of drilling and pop-rivets it got lifted into position on the forks on the back of the tractor a couple of weeks ago.
20 12v 100amp-hr batteries have been wedged in with quake straps to hold them firm.
The control gear includes a Mk 3 controller
The new much more readable display (one of 6 available for configuring and measuring data)
The busses are much more visible without the quake straps
I'll writing up the new controller in due course - its a development of the Atmel Butterfly board device but using an Arduino Mega 2560 board and having USB connection and an SD Card for recording data.
