Thanks, Thats is almost exactly the size of the bottle I've got, only slightly shorter and fatter. It won't fit my frame then. I guess I have a strange frame.
It was very fun to try 80v at 30amps, but the amount of juice that motor consumes at slightly higher speed was extreme and a deal breaker for me. Back to 36v for me.
atcspaul:
have you tried a regular 48v battery. if I was using for transportation the 48v cruised around 24 mph which was plenty fast. I use the 36v because I do not need to go that fast in the woods plus I need the exercise

No I haven't. I started out trying to keep things within the European legislations and wasn't thinking I would buy the Cycle Analyst. But I got power hungry when going off road and was held back by my too cheap 1C battery. That's why I went a little nuts and tried 74v. It was fun, but I have motorcycle license and that is much faster and not to mention legal.
Now that I have given up on finding a bottle battery I'll probably end up buying a 48v aluminum case rack battery. I'm thinking either the GM battery or one I found from another seller that looks identical to the GM battery with the same looking cells, but with slightly lower stats. They might not have the same BMS. Its a price difference of $160 including shipping. If I'm lucky the battery will fit on the same bracket as my current 36v battery. It seams that good enclosed batteries are hard to find. Most over 2C are shrink wrapped.
EDIT: I decided in favor of the cheaper battery and ordered it. It's decisions like this that costs money in the long run, but I can't bring myself to overspend when there are cheap products around.

I have finally gotten around to precisely measure my shunt and can now edit those previous numbers.
It wasn't 22amps 1750w continues, but rather 28amps and 2190w
Peak wasn't 2800w but actually 3500 watts 8)
