[ausev] Hydrocaps

[Chris Robison]

I *haven't* used these, but I have an opinion to share ...

My understanding about Hydrocaps is that they become very warm as they
effectively bleed off the energy stored in splitting the water into
hydrogen and oxygen, by putting the two gasses back together again. They
get hot enough during use that they degrade and wear out over time. If you
do an equalizing charge with them installed, they'll overheat and it may
ruin them the first time this happens, so occasionally to equalize the
pack you'll need to go over your entire pack and detach them.

I would say, for a similar amount of money, the AquaPro watering caps from
Rover and Rover may be the better idea:

I corresponded with them extensively while I was still planning on using
flooded nicad batteries for my truck, and found them to be extremely
helpful and interested in my project.  They went so far as to offer to try
doing a custom run of caps in ABS plastic instead of their usual
polycarbonate, as ABS is resistant to the nicad's KOH electrolyte and is
compatible with their ultrasonic welding process.  And though they'd never
tried it before, they were still willing to cut me a quantity deal.  
Though ultimately I ended up deciding against using the nicads, I still
can't say enough good things about this company.

A guy in Australia built an EV outfitted with their caps:

Basically the idea is to make watering completely painless -- plug the
connector into a single watering outlet on the exterior of the car, wait
until the water stops flowing (the little plastic spheres in the connector
stop moving) and then unplug. Since you can do this at fairly high
pressure, even a large pack would take seconds to fill. You could
literally do it after every recharge.
