You are no funWhy not just buy a battery - you know, one of those big black things which live under the bonnet. Or in motorhomes usually hidden somewhere else.

Ok, I will give it away. I tripped over this video...
And I already had this in my to buy list at Amazon.
And I was thinking of setting up a combination system. Where I had a LiPo battery in combination with a supercap pack.
I can get LiPo battery packs with 400Amp so 2 in parallel and a supercap bank to give the boost....
But then I found this....
Just messing at the moment with ideas.

Or couple of rags dowsed in paraffin underneathThis was after of course you had heated up the top of the cylinder head with a blowlamp!
Yes ,Citroen are the same. Friend here had a new picasso & battery died . I was amazed at what you had to do just to jump start it ( glad I read book first !!!!) but it was dead as doornail. Then reading what to do re changing it . open drivers window, shut door, turn on ignition, etc. change battery, lean in through window turn on , wait 5 minutes , turn on lights, etc;etc;Hi Karl if I still had my old Iveco ambulance I would have loved to try it all out along side you -just for the adventure- but with this new Relay I fear the leccy bits would blow it's brain It sent it in a tail spin when after we ran the battery down with radio on and jump starting it we decided to couple the batt charger onto the jump start bit --BIG NO some of the small relay's started to buzz and the comp went into overdrive and I had to get mate down to reset everything with his comp -he told me they don't like charging that way -another lesson learned Keep us post at your progress

I like the ideas. I'd have some concerns about using caps. on their own because of the rapid voltage fall-off as most engine ECUs prevent starter engagement below a certain voltage to preserve their own supply. Used in conjunction with LIPOs the problem is solved as long as proper charge control is implemented for the LIPOs - they have charge characteristics very different from lead-acid & become explosive when offended.
If it's any help we simply changed the battery without doing anything out of the ordinary IE undo clamps and retaining strap changed battery over -- It could be that some more warnings lights came on during this time but seeing how it was lit up like a xmas tree cannot say we noticed I know the battery was comp flat so I connected it to another for an hour or so with the charger on -after an hour the charger acepted there was a battery on so went along and took 3 days to charge the battery -it's still holding charge so I may have got away with it If not it's a big battery so I'LL GET 10/15 QUID SCRAPYes ,Citroen are the same.

If I hadn't been reading it in a Citroen handbook I'd have thought it was a joke. Even after it was recovered ( under guarantee) the Citroen dealer couldn't change the battery until Citroen España authorised it because in the book it specifically states that if the battery is going to fail it will do it from new usually in the first 6 months & this was just over.
It is quite easy these days to wipe out an ecu & with an older vehicle it renders it scrap as the replacement cost is so high.
