it may just as well be a modified volt meter, extrapolating voltage vs state of charge, between low and high.

that's the correct description 16S2P 3.2V 10AH LiFePO4 Very nice. How much did you pay for it? here is the link: http://bote-power.en.alibaba.com/productshowimg/1007636177-220014535/lifepo4_battery_48v_20ah.html

on the contrary. Room temperature keeps your battery dry in winter and right in the middle of optimal condition. This chart sums up the best operating temperature for your battery: source: http://www.mpoweruk.com/lithium_failures.htm

this is a problem affecting mostly small lipo packs without BMS. If you keep within 2C, that's what most BMSes do by default anyway, you'll get 90%-95% of your battery's capacity.

not that insignificant. his cells are similar to the blue plot (UR18650F, 2600mAH). If he rides slowly, more than hour, he gets 95%. If he flattens his battery in less than 20 minutes, then the drop will be huge. source: http://batteryuniversity.com/learn/article/calculating_the_battery_runtime

yes.

are you saying that your dealer expects a new wheel from China after their lunar new year holiday? that can't be right, the staff come back at the beginning at March, even if they send you a new wheel, the boat takes at least 6 weeks to arrrive, you won't see something from China until early...

48V at low speed on a direct drive? - not a good idea. At relatively low speed (under 200 RPM for 48V DD motors), the motor efficiency is below 50%, most of your battery power is going to turn into heat. DD motors shine only when you can push 20A or more into the copper.

didn't they jump the gun a little bit? they should have concentrated their marketing effort to lower the cost of plugin hybrids and waited for their wider adoption. Plugin hybrids do not require any additional infrastructure while still gain in MPG and lessen pollution.

you bought the bike directly from the importer, they have your details. If you sell it on, you'll pass on your invoice to the next owner.

as flecc said, you can't have CE marking without test.

the battery's electronics needs to be kept dry. In a garage, the humidity in the air will condense inside the casing damaging the electronics and increases leakage current. We are talking about a few mA here, but the effect can be devastating on the closing up of the tiny pores in the cells...

source: http://en.wikipedia.org/wiki/Drag_%28physics%29 The required power is proportional to the cube of the speed as per this formula:

it may recover. Just take it out for another ride.

yes, it can send you flying. You need a solid bike with good shocks.

The Harmony looks gorgeous with that downtube battery. Looking forward to reading your review

the low speed option is usually better for hillclimbing. For £1000, speed + hill climbing, 48V 500W BPM with 48V 15AH battery and 25A controller. It's difficult to find a battery with that much capacity that'll go on the downtube. Ask member mechaniker to quote, I reckon it's about £700...

welcome to the forum. You did well with that bike. Nice design, excellent buy. For those who may be interested in Velocious, here is the link to their website: http://velocious.myshopify.com/pages/our-ebikes BTW, all woosh bikes are under £1,000 and come with kevlar puncture resist tyres as...

a friend told me (unverified information) that if you have a multicar insurance policy (2 cars or more), they can include your s-pedelec or e-moped in their cover for free.

I called and talked to Carole Nash 0800 144 4645 last month about insuring an e-moped. They said they will quote when I have the bike registered. Another company is https://www.bikesure.co.uk - they specialize in e-bikes.
