10 years ago a novel DIYer came up with a dang fine instrument to monitor his system. It was the Cycle Analyst from ebikes. It was designed for bicycles but it's an amazing instrument and works well with EV's. It calculates your watthours per mile, monitors the pack voltage and current and keeps a tally on your AH consumed. Usable also as a fuel gauge. Tons of other data at your fingertips.

At the time they had a unit that was not in an enclosure so we could install it in our own. I built one and put a Controller Ready LED in it as well as a pack balance meter. I should post a video. It even has some digital interface options I believe but I don't use that.

I did a quick search on it yesterday and found no recent activity. There may be a better option out there but it suits my needs!

I believe that was Justin, from E-Bikes.ca

EV pioneer. And he stepped in to save EndlessSphere from the Vertical Scope buyout that all the other forums suffered from (us included), out of his own pocket.

He promoted early E-bike work by cycling coast-to-coast on battery power alone. He invented a EV unicycle. I think he recently did the France-to-China solar-only (battery okay, but no plug in) e-bike trip on a back-to-back tandem with his fiance, departing half way in Iran for home for them to get married.

His current project is some acknowledgely godawful boat powered by spare e-bike parts.

Hell of a guy.

Funny, like barging into a physics forum telling tales of this guy called Einstein as if we all don't know Justin's corpus of work here

Not what I'd label a DIYer really, went pro a long time ago.

OP there is a demand for a CAV3 based unit with a modern display

maybe even an MCU based meta-meta controller to add functionality.

Any chance that sort of project would be easy for you?

John I have zero interest in anything complicated at my age. I built mine 13 years ago and this post was based on what I RECALL from that time. I don't know the origins or who came up with the idea, it's immaterial to the conversation. The conversation is about the CA and it's usefulness to DIYers. But IT WAS A DAMN GOOD DEVICE and I told them so yesterday. It still works great and IS SIMPLE yet provides a plethora of data to the operator.

Is this the same CA thunderstruck-ev lists in the instrumentation section of their web site? If so, pretty amazing for the price!
