Worth looking at those Shorai batteries and the maintenance charger. See YellowPeril's post above. The ability to balance the cells and reduce the charge to a storage level is significant and the pricing seems very competitive. Quote Link to comment Share on other sites More sharing options...
550superfast Posted September 7, 2016 Report Share Posted September 7, 2016 Thanks - but I am not sure on how to compare the specs. I would need to rely on people with knowledge. 1 Quote https://www.youtube.com/user/400superamerica Link to comment Share on other sites More sharing options...

I may have a try, though ! If that battery can be made to work then that looks like best bang for buck really doesn't it. Will you be trying this? I suppose I'm like a few people.. id rather be a sheep and do something once somebody else has already done it. This battery has a greater CCA than the Varta silver used in the CR. Is the CCA the main thing you need to look at? obviously the terminals are different too. also 4.3lb is less than 2kg Edited September 7, 2016 by RedViper Quote Link to comment Share on other sites More sharing options...

Danelaw Posted November 2, 2016 Report Share Posted November 2, 2016 For my Evora I got several Ultrabatt Multi-mighty battery units and joined them together. It's a modular approach to light-weight Lithium batteries for motorbikes and cars and has proved excellent so far in my car. I made my own bracket with aluminium and a velcro tie and there's a photo somewhere on an Evora forum thread about batteries if anybody is interested.

Tthe std cars use a 72ah and the 350 versions list as 74ah and 63ah My owm 360 cup has a Varta E43 72AH at 17.4 KGS As usual, Dave is correct. The CR battery isn't that light. I understand the factory as fitted the Super B lithium batteries to some of the motorsport cars. I'm going to try this one (3.6kg)…… http://www.super-b.com/en/automotive/sb12v20p-sc Quote Jack2008 2-Eleven2015 Exige V6 CupR Track videos ... http://www.youtube.com/jackcup2010 Lotus Challenge Series ULTRA Class champion2012 Lotus CUP USA OPEN Class champion Link to comment Share on other sites More sharing options...
Popular Post Seriouslylotus Posted November 10, 2016 Popular Post Report Share Posted November 10, 2016 (edited) I am using the Braille GU1R.......Starts the V6 with no issues from both cold and hot. The bracket I have had mad is under 200g, so the battery 'package' is just under 3.2kgs. The Standard battery and steel carrier in my car come in at 19kgs I think a 15.8 kg saving is brilliant and so very simple!! The bracket is carbon made by a new company called Osport design , its super light and strong, The one shown is prototype no 3 or 4 I cant remember!! The final version will be almost identical apart from the mounting points will be moved to help get the battery fitted position a little better. The final price will be confirmed once I have the finished carrier, but a ball park figure will be about £700-750 + vat for the battery and carrier and about 750-800+vat for a full kit including the correct lithium charger Edited November 10, 2016 by Seriouslylotus 6 Quote Link to comment Share on other sites More sharing options...
French Frie Posted November 10, 2016 Report Share Posted November 10, 2016 Great ! Thanks for the feedback ... and beautiful bracket ! Do you think that the battery can be relocated at the same time, in order to gain some luggage space (even if the fuses panel remains) ? I saw that on a Elise, with the battery relocated in the engine bay ... Quote Link to comment Share on other sites More sharing options...

I haven't thought of moving the battery as that involves possibly new battery leads!!! Quote Link to comment Share on other sites More sharing options...

RedViper Posted November 10, 2016 Report Share Posted November 10, 2016 That's a very impressive solution. It's a shame the battery is so eye wateringly expensive.

Battery does seem expensive but....... How much would you have to send on carbon parts to save 15.8 kgs? To put that into perspective, the forged wheels are over £1500 + vat as a factory fit option from lotus and save 8kgs!!!! From a weight saving point of view makes the battery an absolute bargain (do I sound like a cheesy salesman??)

RedViper Posted November 10, 2016 Report Share Posted November 10, 2016 (edited) Ha ha. It is a very impressive weight saving like. At least with the wheels you can see where your money has gone.

Jack Posted November 12, 2016 Report Share Posted November 12, 2016 Update: Just pulled the stock battery from the CupR, weight 15Kg (33 lbs); replaced it with the Super B lithium battery, weight 3.6Kg (7.9 lbs) --- weight savings of 11Kg (~25 lbs). Fits perfectly within CupR's battery box using factory mounting strap --- Quote Jack2008 2-Eleven2015 Exige V6 CupR Track videos ... http://www.youtube.com/jackcup2010 Lotus Challenge Series ULTRA Class champion2012 Lotus CUP USA OPEN Class champion Link to comment Share on other sites More sharing options...
alias23 Posted November 16, 2016 Report Share Posted November 16, 2016 A friend of mine has been using the Shorai now for a few months with no problem. He has added a cut off switch and turns it off when the car is in storage.http://shoraipower.com/lfx36l3-bs12-p130 A hell of a lot more reasonable price wise. Its on the list!

Jack Posted November 16, 2016 Report Share Posted November 16, 2016 @alias23 Imran, you should look into the Super B -- it was "only" 1000 US$ You could call this UK dealer and see what the cost is in the UK ..... +441491822000 Used extensively in motorsport applications...... from their website.....

Looks like a decent option. Be good if you could do a little "How-To" when you get one Imran. I think I could stomach about £300. Postage shouldn't be too bad either at that weight. Be good to get an idea how long it would last without being on trickle charger. Aslong as it lasted 3-4 days that would do me ?

MartynB Posted November 16, 2016 Report Share Posted November 16, 2016 @Jack I assume you're using the SB12V20P-SC What do you see as the benefits vs the Shorai units? They both appear competent, with the Shorai ones being cheaper and allowing cell tap access for balancing if needed. This would be the dealer in the UK... http://race.parts/Catalogue/Electrical/Batteries-and-Accessories/Batteries/Super-B-Lithium-Batteries Quote Link to comment Share on other sites More sharing options...
Jack Posted November 17, 2016 Report Share Posted November 17, 2016 @MartynBYes, correct. The 20P-SC was close to the dimensions of the stock VARTA that came with the CupR, so it fit nicely w/in the CupR's battery box. I can't provide any meaningful input on the differences between the two brands. I chose the Super B upon the advice of my race shop. They indicated that their experience with the Super B over an extended use period in other cars was excellent and that Lotus Motorsport had recommended the battery to them some time ago. 1 Quote Jack2008 2-Eleven2015 Exige V6 CupR Track videos ... http://www.youtube.com/jackcup2010 Lotus Challenge Series ULTRA Class champion2012 Lotus CUP USA OPEN Class champion Link to comment Share on other sites More sharing options...
MartynB Posted November 17, 2016 Report Share Posted November 17, 2016 Interesting. Given the fit and that recommendation I totally understand your choice. Might be worth getting some terminal covers fabricated, maybe 3D printed. Aluminium is much like magnesium when it burns Quote Link to comment Share on other sites More sharing options...
