heds954 Posted July 1, 2012 Report Share Posted July 1, 2012 The biggest issue I found is trying to find reputable suppliers of A123 cells. There is one firm that I was pointed to by many sources but seemingly have been devoid of stocks for many months (as I've set up a dubry to send me an email when they come back in stock). I've got an agreement whereby as soon as I get a pack of them I can buy the necessary hardware to make a lightweight battery from it all, but with no cells forthcoming I'm having to bide my time. Anywho, that's for my project bike. In the mean time I've bought a lighweight battery from MOTY in the States for my cbr6rr. I've bought the hard case version and it's about the size of my fist and weighs sum total of fuckall. There's only two rules, don't leave it on the bike for any length of time as it'll drain, and definitely don't leave it for any length of time if it drops below freezing, but then I've seen vids of big bikes cranking over perfectly whilst surrounded by snow. I ordered mine on the Friday and it was here from the US the following Monday. Not many bike places can achieve that level of service in the UK!!

Ta http://www.electricw...spx?product=946 These are exactly the same as the more expensive options, and are fine on a carbed IL4 600 for day to day use edit- looking at the link Heds posted, they're pretty good value too.

Do you need any special leads, or can you fix it directly to the existing battery leads? Or did you hack off the supplied connectors and fit new ones?

750 Gixxer Posted August 8, 2012 Report Share Posted August 8, 2012 I have been running 4 A123 cells i a homemade frame (Ripperton rip off) in my GSXR 750 k1 roadbike for a bit over 2 years. The only problem i had was not enough cranking power when it the temperatur was below aprox. 10 degrees. And i have only used a normal battery charger (Ctek), did'nt even take it off the bike or charge it doing winter. This spring i started having to charge the battery every day to be able to start the bike. So i made a new 8 cell frame and ordered 4 new cells on evilbay from a seller in Singapore. All was dandy for the next couple of weeks. Then i did'nt use the bike for about 5 week, when i wanted to start it again it was completly discharged...... Managed to charge 3 but 5 are dead. Anyone know why this has happened? Is it because of not using a proper charger. Link to comment Share on other sites More sharing options...

Pierre Posted August 9, 2012 Report Share Posted August 9, 2012 Managed to charge 3 but 5 are dead. Anyone know why this has happened? Is it because of not using a proper charger. I could be wrong (and probably am) but I think if you've used 4 old with 4 new and havent balanced them, then the 4 new ones are dragged down to the old ones level, and is it 9v they die at? I havent fitted mine yet, cos my aprilia has an imobiliser that would drain it and I dont want to stick the optimate on. Gonna get a big red push-to-isolate button mounted next to the battery to cut everything Link to comment Share on other sites More sharing options...

Toseland's Eyebrows Posted August 10, 2012 Report Share Posted August 10, 2012 I've got a bike that runs total loss, can you charge these using an optimate? Link to comment Share on other sites More sharing options...
Pierre Posted August 10, 2012 Report Share Posted August 10, 2012 No, youre better off with an old fashioned charge-it-fking-quick charger. Depending on the battery they take up to a 20a charge which will charge in 15 mins (ie. between sessions , while the tire warmers are on). Trickle charge kills them Link to comment Share on other sites More sharing options...
Sideshow Pob Posted August 10, 2012 Report Share Posted August 10, 2012 The A123's need to be very well balanced and the Ultrabatt batteries do that very well as they have a BMS chip built in (Battery Management Chip). Not sure if Ultrabatt actually use A123 cells but a BMS on a multicell battery is the best way to go. If you want to buy A123 cells then these seem pretty good, bought quite a few and they are all very well balanced http://www.hobbyking.com/hobbyking/store/__16575__A123_3_3VB_Lithium_Ion_2300Ah_Single_Cell_Battery.html Charging them is a whole different ball game as you need to charge them up to 14.5V and 'normal' chargers cut off well before then. If you charge a LifeP04 up to 13.5 then that big initial kick will be missing. Link to comment Share on other sites More sharing options...

Timbo S2 Posted November 17, 2012 Report Share Posted November 17, 2012 Sorry to bring this up again. I just fitted a ballistic battery to the srad, saved about 2.5kg and saved some additional space in the tail to re-locate some of the electrics! Well worth the money.
