Front Battery Box

I've done a lot of procastination for the front battery box.  A lot has to do with the price of batteries, initially I want 160Ah Thunderskys at 144V to give good top speed and distance.  As I've changed jobs money is a bit tighter than it used to be so I've been looking at alternatives.  There are now 90Ah, 100Ah, and 120Ah to choose from either Thundersky or Sky Energy.  Packaging is similar in size and I've compromised from my original 160Ah to go for the 120Ah from Sky.  The height of the batteries is the same as the 160Ah but have the same footprint as the 90Ah also they are 3.4V as opposed to 3.2V.  This should give me a range of 80-100km with a top speed of 120km+.

Now I can organise my front battery box to suit.  I'll have 12 batteries in one long string.  The box cost me AUS$250 to get made and I'm now working out suitable mounting.  I'll use the existing mounts at the front where the radiator was and look at mounting through the chassis rails, to do this I'll need to drill a hole then sleeve it so when the bolt is tightened up it doesn't deform the rail.
