Battery re-location.?
Discussion
Use an Odyssey PC1100 battery and get the ally cage that goes with it and mount it above the fuel tank in the middle. Get batt cable from vehicle wiring products and I ran mine to the right, over the wing and down the back of the door sill, then through the floor, along into the transmission tunnel and forward.
I highly recommend getting a battery brain as well with remote. This will stop the car ever going flat and means you'll always be able to get into the boot.

These Odyssey batteries would fit in the storage hole behind the passenger seat. Cables could run under the centre console. That way it would be nicely protected from accidental shorting out by metal objects and it leaves the boot free
I don't know, I used to have a pc925 which would have fit there, but it did struggle a bit on hot start or very cold days. The 1000 won't fit there but fits very neatly above the fuel tank and it starts with much more gusto in all conditions and can be left a lot longer even without the battery brain. I'd definitely recommend it over the smaller types having had 2 small ones before.With lead acid batteries you can't beat the rules of physics and chemistry, so quite simply bigger is always better.
And how heavy a battery is for a given size tells you a lot about its quality, the rule here is also simple... the heavier the better.
Four years ago I fitted an Odyssey PC1500 which is the same size the 072 battery TVR specified, Ok so there's no extra leg room but I never sit in the passenger seat so who gives a monkey's about that?

The difference comes when you study the spec on this 22.4kg heavy weight
Upgrade your starter cable to 50mm2, add a direct from starter mounting bolt to battery earth in the same cable, add a Battery Brain remote battery disconnect device then bypass or replace the poorly wired Meta immobiliser and you'll eliminate 99% of all the classic TVR starting disappointments.

Mine's in the boot (with fat cables) on top of the fuel tank. Original battery, neat installation, smart box. No pictures but I can take one and post if interested.
Added bonus (or one of the main selling points, IMHO) is the increased passenger leg room for tall, touring non-drivers.

Bloody hell Dave see what you mean And how heavy a battery is for a given size tells you a lot about its quality, the rule here is also simple... the heavier the better.

and I thought this was a bit of a monster (not quite on par with the PC1500 though) but at £50 and an hours drive I couldn't resist

Is that the standard 072 battery? This is interesting, the only thing putting me off is that my 072 is only 12 months old so I don't want to waste itAdded bonus (or one of the main selling points, IMHO) is the increased passenger leg room for tall, touring non-drivers.

Bargain Simon, a fantastic battery and a great buy there mate and I thought this was a bit of a monster (not quite on par with the PC1500 though) but at £50 and an hours drive I couldn't resist 
The truth is my Odyssey PC1500 is probably total overkill, you do get to a point where there's no point in fitting a more grunty and bigger and bigger battery.
Yes it was expensive, but then again I got it at cost from one of my tame suppliers I'd fed a lot of business too over the years.
It's not like I'm winching or going on African expeditions which is the target market for the PC1500, but I got so sick of failed start disappointments I needed to sort it, the Odyssey was just one element in a chain of solutions I implemented.
A Meta bypass or properly wired replacement certainly improves TVR Chimaera reliability no end, as does a new heaver gauge starter cable followed by an addition earth cable and in my case a new starter motor.
They all played their part, but lets not forget the Battery Brain which has been an absolute God send for lay-ups of over two weeks when I didn't have a mains point, but also for its additional level of security and as a safety feature too

but like you said earlier bigger is better my previous 075 Bosch S3 lasted over 7 years on my car but I use a battery minder when the car is out of service especially with the constant drain of the alarm although the Cobra cat 1 I have fitted is very frugal in that department The best thing to do with the meta is bin it. I replaced mine with an Autowatch 457rli years ago and it's been faultless and it's much smaller. It still has triple immobiliser circuits but I wired mine up differently to TVR so it really does make it impossible to start, but no current really goes through it. I've also put in a big waterproof hella 100amp relay that sits under the bonnet and when activated by the ignition barrel, it pulls current directly from the 100amp fuse and feeds it into the starter motor. This way the current never even comes into the car, so with the big odyssey battery I'm hoping it will solve all of my old hot start problems (although to be honest they all seemed to be battery related anyway)
Wired correctly with a relay fitted to the starter solenoid energizer circuit the modular immobilizer relays are only switching milliamps anyway for fuel pump, starter relays, etc, sounds complicated but its not my Cobra system as been trouble free for over 10 years and I am still on the 1st fob battery but I have a touch key just in case but no surprise really its been installed correctly which in relative terms concerning modern vehicle electrics and regardless of what you hear is a piece of piss on these cars

It's whatever came out of the footwell, transferred straight to the boot. I'll try to remember to take a picture over the weekend a post it.pb450 said:
