Remember not to fill them completely until after charging as the water/acid solution will expand when charging. Just put in enough to cover the plates, then charge them up.

Thanks - I seemed to recall reading something to that effect, so that's what we did/are doing.

Somewhere I read that it's common for metro EV conversions to end up with the batts in back and be too heavy in the rear (and who wants that? ). I'm not sure if that's true. It'd be good if you could balance it, but it'd also be pretty good if none of the batts were in the passenger compartment.

But I thought the inability to carry 4 adults was a stock feature.

j/k - I have no idea

You've got a point. And in this day and age, you'd be hard pressed to get 4 adults in that Metro without exceeding its 695lb weight rating! Never mind any luggage. (I wonder if the GVWR changed when they switched to the Blackfly's body style - I've never looked.)

So this evening I made up 4 cardboard boxes - "battery mockups". Easier to monkey around with these under the hood to figure out placement and rack options than with the real things. I've seen a few people do this.

It looks like the hours meter will run constantly with the precharge resistor across the pot contactor--perhaps you should change the negative connection to be on the other side of the key switch contactor?

Good eye. I'm not sure but I think I may have introduced that change when I offered the "fuse re-drawing with a single ground."

Maybe it should be:
