I know there's lot's of discussions about EV Insights and various battery mods/upgrades on the site but I wanted to start a new thread for two reasons.

1) After much thought I'm going to go with an upgraded Li-ion 50 ah battery pack in my Insight to make a phev and not a full electric at this stage. I can save money by converting one of my existing cars, so that means I have the £2000 budget needed for a set of 40x50aha Thunder Sky LCP cells.

2) I also want to see if anyone on here in the UK wants to join in a UK Bulk purchase of TS cells so we can get the price down. My post's on several EV sites are hoping to get some support from the UK EV Community.

"I'm starting a thread on the UK BVS society forum to discuss this
idea, and to gather firm expressions of interest and commitment from
other UK EV enthusiasts who would be up for participating in another
UK bulk purchase of TS cells. Note the bulk purchase is for LCP/LMP
cells only not LFP which have licensing problems.

You need to register on the BVS forum to particiapte or post re this,
and all discussion will take place on the BVS forum thread.

This would be run along the same lines as the first UK one in 2003,
and would involve money up front to the UK agent (Reap systems) and a
minimum 12 week delivery time via sea to Southampton, where all cells
would be collected by the individuals from the group. You should bank
on no guarantees whatsoever, and make your mind up on that basis.
This bulk purchase is not affiliated with or backed by the BVS or any
individual.

The price I/we are aiming for is £1.00 - £1.10 per Ah inc vat and
import duty/shipping etc. So a 50ah cell will cost £50-£55 each. We
could get lucky and depending on total quantity maybe get a lower
price!

I'm happy to put my money up front as I did before for a new set of
45 x TS-LCP50AHA Cells for my Honda Insight PHEV project.

Add your name and comments to this thread together with details and
quantities of cells your are interested in. Note no LFP cells!

I will liase with Reap Systems so questions on the forum only at this
time please, I know they are busy moving offices.

Final commitment will be required by the end of April 08. This gives
us a month to spread the word and make up our minds. If we cannot
raise a big enough order then the purchase may not go ahead at all,
so the more the merrier.

I'm happy to build up the TS cells into a useable battery pack and I can take the sensors and heat sensing strips etc out of one of my spare IMA packs and incorporate them into the new pack or fake the signals as required.

Now asuming I have a functioning battery pack of say 45 ah useable capacity compared to the 4.5 ah of a normal IMA pack, how can I/we con the current sensors in the IMA system to think it's still dealing with a 4.5 ah pack and register the charge/soc correctly, Divide current sensor outputs by 10? Ideas?

I will probably add a little pic and lcd display to monitor battery pack parameters independently of the car systems as fail safe system.
