Hi Richard, We already use a CA and record data manually be this requires someone to watch the thing and is very labour intensive. Hi Steve, Ray, my engineer has sorted that out, I'll pass on the details once we have tested. Hi disadvantage, thanks for the link, I will have a look at this...

Hi Doc, I've got the 'Big Load' covered and I will see the Labview rep next week. Can you recommend a ni daq card for the job, I'm having trouble as they all seem far too complicated for this application. Many thanks, Ian

Thanks guys, I'll pass these on to my engineer. My experience comes from using a Cycle Analyst and its only that basic information we need, but recorded on a PC. Labview and Cadex seem overkill, some simple V & A graphs to track voltage sag for a given rate of discharge and total Wh discharged...

Hi All, In the coming weeks I will be building some rather large LiFeBATT packs. 50S2P 150V 20Ah for a project which will be announced in February or March. We are designing a charger and a 'load' for testing but we want to record volts, amps, Wh's consumed etc, during the cycle testing. Is...

I had an email from Mark yesterday confirming that the new motor will only take a single speed. I think Knoxie found that torque between the 250 and 320rpm motors was very similar, the 320 just faster.

Excellent news Bob, welcome to the team.

Before I bothered anyone here, I did spend several hours calling around, visiting Maplin, the UK equivalent of Radio Shack, I guess, and surfing the net. But nothing was as big nor as inexpensive. Even farnell.co.uk doesn't offer anything bigger than 114mm ! 492,706 products, my ARSE! Sorry...

Would you believe BatterySpace wanted $45 to ship 4 feet of their 238mm Heavy-Duty Thermal Shrink Wrap Tube ($3.99 per foot) to the UK! :shock: Does anybody know a supplier in the UK, or someone in the US who charges a reasonable fee for shipping? Thanks, Ian

Hi All, Saw this on EV Album and immediately wished I'd gone this route :mrgreen: The rear dropouts look a bit weedy for an X5. http://www.austinev.org/evalbum/1437 It also needs a nice set of high bars 8) Ian

Hi Matt, I have used Farnell.co.uk in the past. These look good, 1.2V NIMH D 7AH. 35A max current. http://uk.farnell.com/jsp/Electrical/Batteries,+Chargers+&+Holders/GP+BATTERIES/GP700DH1A1P/displayProduct.jsp?sku=1269675&_requestid=235240 They have larger but they get very expensive. When I...

Hi Bill, It is indeed amazing that you participate here at Endless Sphere, we all share your desire to push the technology faster and faster. Also, I hope your now fully recovered from your little 'incident'. Another record has certainly restored any dignity you lost. Can I ask what are the...

Hi Jozzer, Great video's but I have to agree with Knoxie, get a lid. When I was 16, I told my Dad I wanted a motorcycle, that evening he returned from work (he was an insurance underwriter) with a briefcase full of gory photo's of motorcyclists various bloody parts, literally! Of course being...

That is an excellent solution to the battery storage problem, especially as it so easy to remove and carry indoors to your charging station, or if you need to leave the bike chained up in public. I can't remove my batt's without a spanner and 20 minutes. So, I have a hidden cut off switch and...

I too have arthritis, pretty much everywhere. I found the half throttle a lot easier. I dislocated my thumb about six months ago on a thumb throttle. But fortunatley, as the thumb doesn't have any cartilige, it poped back in straight away :oops: I am in the process, for the last six months...

This is the cost / performace setup between my brushed / brushless setups; Brushed - Powerbyke geared hub motor and 36V 40Amp scooter controller, £105 and 15mph. 7mph up an 8% hill. Brushless - Puma geared hub motor and C'lyte 35Amp controller, £440 and 20mph. 14mph up an 8% hill...
