Default Lightweight batteries

Is anyone using one of the lightweight racing type batteries like the Braille? I'm considering moving my battery to the engine bay to clean up the boot for a fuel cell installation. Anyone done this? I'm running a D-series and I think I might have just enough room on the bulkhead where the master cylinders used to be to mount a small size battery.

I use an oddessey, pc680

It seems to crank well but the voltage (12.8v full) does drop fairly quick if not used with the ecu / gps / headunit connected. I trickle charge it with an Accucell 6 every now and then, trick is not to let it go over 14.7v which many normal battery chargers would.

If you have a proper battery disconnect and isolate it when not in use it will hold full charge for at least a year, also they like cold weather and can provide more power than when warm.

For weight distribution you’re better leaving it in the boot or if you have to move it maybe go under the rear bench? Just a suggestion

Also looking at getting one of these, so can’t offer any experience with them.

I got one brand new 7 years ago , I just wanted to try one,
Seemed like a good idia at the time,
Time whent on and whent to use it but found it was as dead as a dodo, I tryed to charge it exstra but it was scrap,
It was my fault but lost faith in it and followed my instinck,s
And got a good size one,
I have since spoke to pals that use them in Motorsport applications and they do work but a found not to be man enough for the long hall and the dimands of winter reliability,

I vaguely remember reading about a production ICE car that had a battery that wasn't lead-acid but lead-acid has yet to be superseded, it's had a very long run that's for sure.

I'm putting a 10-12 gallon fuel cell in the boot, so I don't think I'll miss the weight of the battery. And the idea is to get it out of the cabin, so under the seat is not really an option. I've done some reading and it seems like the main thing is to have a battery cutoff and to use the proper charger to keep it topped off. I guess I'll see how it goes.
