many thanks, by the way do you have a 9S charger (an dif so which, and does one get say 13 S Chargers)?

as an aside, does anyone know how much torque a direct drive motor like that produces? if a kalkhoff impulse 2 produces 70nm, a BPM something like 60 with 36V/20A, a TCM something like 50 (these are just my half-baked guesses, feel free to correct), where would a direct drive motor be? many thanks

apologies for not answering the question (im running a lipo setup too and am as interested in an answer in fact), I was wondering what made you choose these batteries rather than hobbykings 16Ah 6S which would give much more Ah for the money?

you're right, it would complicate things, I think id remove the tape and only if that didn't do it add it - it depends which controller it is - I have an s12sh that sometimes gets hot, but its not an issue ito switching off. It's never really hot in the UK so I'm sure this is overthinking it...

I was astonished to hear that Brompton(I have one) only guarantee their frames up to 125kg, god knows what happens after that. I always thought bicycle frames were indestructible, happy you survived.

having seen cwah's bikes I assumed he may be running a 48V controller at 58V and so within a very narrow margin of it maximum capacity, in which case it may be running hot normally? Other than removing the black tape and allowing the heat sink to work, you could fit a computer processor water...

In my life that is very true: the choice isn't between doing a 23 mile commute on a pedelec or a normal bicycle - its between a pedelecs and a car. A normal bicycle would always feel too difficult/sweaty/awful in winter to do it with. a pedelecs has to be healthier than sitting in a car. a...

But it is significantly cheaper,if one has a mountain drive shaped hole in ones life

I have the same experience,my 13ah oxydrive kit is derestricted and tops out around 22 to 24 mph,I cycle home 13 miles today constantly 24 to 25 mph on a racer with it,the LCD scd shows the system uses almost no energy 70% of the time,the Max energy it gives the other 30% against hills makes it...

you lucky retirees, wasn't even aware its Wimbledon really, two hours more at work and it's a cycle home through the shires

apologies should have googled, found this it makes it seem pretty straightforward with BMS to end up with 16A/h 48V for around £180 (with BMS) unless I'm missing something?

many thanks, 6s and 4s is cheap and big http://www.hobbyking.co.uk/hobbyking/store/__66310__Multistar_16000mAh_6s_10c_EU_Warehouse_.html but 7S isn't. apologies for a noob question - but is it as simple as separating a pouch from a 6S of similar size (say a 16A/h) and adding it to another to...

Many thanks, that's very helpful info. is BMS battery still the best place to buy bottle batteries (it's not exactly cheap with freight etc). Why, as a complete aside isn't it feasible to make bottle batteries with lipo pouches such as, I gather large lipos from say hobby king are made off? with...

apologies for a slight detour, but how hard is it to build a 48V battery with BMS from Samsung cells? funds are very limited an I have a city bike running on 12S lipos and my experience with an oxydrive kit made me realise bottle batteries are so much easier to live with

FWIW practical bikes sell this cheap, strong, well made 400 mm quill stem: http://practicalcycles.com/products/242538--humpert-chrome-steel-tall-1-inch-dutch-handlebar-stem.aspx I put one on a Raleigh twenty I installed a cheap set of bmx forks on - it provides enough height for the talllest...

at that price, INHO, the biggest problem will be the crap components and low quality untrue rims on the bicycle you get (though if absolutely pushed to do it I'd muster all my misplaced optimism and get a Tesco hopper for £350 and replace the wheels and brakes), much better I'd say to get an...

I came home from café where I used internet yeste4rday and couldn't access an email address I use to purchase stuff - my usual password didn't work - so, being a neurotic sort, I frantically changed my password. then, around half an hour later received an email from Hotmail about "unusual...

yes, I saw the first bit about classic cars and suddenly thought the same (that its much better than I thought), I never agreed with most of Clarkson's views, but say what one will, he presented a different view on reality, not some conforming insider mainstream crap

i invariably get muddled about this - not least because plugging it in first and switching it on can go with a spark as one plugs it into the battery, for being clear: is it plug into wall, plug into charger, switch on at wall?

I doubt its politics,the BBC is an institution,I work in one ,the NHS,in my experience promotion and demotion in institutions come down to an unsavoury blend of sycophancy and narcisism
