Hi Dave, have found this Panasonic ,pack which weighs less than 2kg. http://www.alibaba.com/product-detail/OEM-Model-rear-rack-panasonic-cell_1777137418.html Does this look ok? Thanks Joneser

For non technical types like me it is difficult. Do panasonic sell 36V 5Ah (or other) e bike batteries with charger? hobbyking seems to be a bewildering list of cells but no packs ready to go.

Having googled Li NCM IT seems they are not as good because of voltage drop.

would be tempting to buy it all from BMS. I could go for a FSMTB pannier rack and fit a flat set on the rack in a bag. There are 3 options on BMS: Li-NiCoMn or Li-Ion NiCoMn or LiFePo4 The Li-NiCoMn is much lighter (2.5kg compared to 3.5kg). Good to choose on this basis?

Thanks Dave, On my q75 I use 2x6s a123's which have proved perfect for my commute. I guess the q100 will draw a bit more juice. Could you recommend a 3 to 4Ah pack? Cheers Joneser

Hi Dave, Thank you very much. You talk about rear motors, I was thinking front hub - did you refer to rears because that is what you would recommend for a FSMTB? Cheers Joneser

Hi, i may be remembered on this forum from a year ago when I did a q75 conversion. Quick update on that - its probably done about 12,000 miles and still going strong (although the motor is probably only on for 1/4 of that distance). I now want to do a full suspension mountain bike conversion...

the only other thing is i redid the connections - added 3 pin mains plug and replaced battery and charger connections with Deans. But I guess it wouldn't have worked to start with if I had connected it wrongly.

About £150 including delivery (plus they would only accept bank transfer which was another 30 quid or something silly).

Well its all wrapped up in that blue stuff. Before asking Forzatec I thought I'd see if the forum had any ideas first. I guess if Forzatec ignore me I could try opening it up.

Well I finally got a saddlebag big enough for the 5Ah Forzatec battery so I tried it on my commute yesterday and it was a total flop - ran out half way into the easy leg of the commute. Charged it for 4 hours at work but it stayed at 15V so cycled home with no power. At least I have my A123's...

Hello Jerry I have a quote for £1.25 per spoke including brass nipples for my brompton Q85 conversion. For the radial length i have knocked off 1.2mm from what the on line calculator recommended. Does this sound ok to you? Much appreciated. Joneser

Strange. Just trying to move this on an re-did the calculator and got a slightly different result: Complete wheel data Hub: q85, front Left flange ⌀: 108 mm Right flange ⌀: 108 mm Centre to left: 20 mm Centre to right: 20 mm Spoke hole ⌀: 3 mm Rim: Sun CR18 ERD ⌀: 340 mm OSB: 0 mm Size: Tension...

"Or equally I could ease off a bit on the effort I put in, so the ride takes the same amount of time, but I'll be using loads less effort which will mean I'm fresher in the evenings or weekends to go on actual rides." The beauty for me is the flexibility. My commute is 10 miles with big long...

Genius. Ideal for winter time washing even if you do have an outside tap. Just don't use the expensive facial wash.

Hi my SJS 36 hole rim for Q85 Brompton conversion arrived today. I got the local bike shop to measure and lace my full size conversion but thought I might try this time. So questions - I'm not sure how accurate measurements need to be - how should I measure? Are some callipers best? Or has...

Cycled in today and used 1.4Ah and the cells were only down to about 3.3V. Perfect! Brought my Turnigy in as I wanted to check something and it is happening again – one of the cells is charging faster (the same cell in each pack (why would that be)). They start off balanced but when they all...

Thanks Dave. So with lifepo's bulk over charging is not a big deal but running them down should always be followed by balanced charging. That a fair summary? Jerry sorry for hi jacking your thread.

I have 2 cheap bulk chargers - 1 at work and 1 at home. They look the same. The one at home measures 41.4V using my cheap Volt meter. Assuming my charger at work is the same, why is it charging the batteries to 44.8V? Or maybe the charger at work is different and I should bring in my Volt meter...
