Not 'he', but the biggest battery supplier in Belgium (where else ;)) 'Battery Supplies' - no VAT, quite handy delivery-wise. Only £15 per unit... If you guys are interested, maybe we can make a multiple order and drop the price even lower - I seem to have made a good contact, so would...

New low cost 'drop-in' battery supplier... Some good news on the 'drop-in' battery front. After months of searching, I've finally found a major European supplier who'll provide a 6 month warranty with very competitive pricing :D Here are the one-off prices, including charger and delivery...

That's interesting! :) @d8veh: when constructing the cruise control, i guess you measured the voltage the throttle presents to the motor controller - is it in the range 0->batt voltage, or is the higher end voltage lower than batt voltage? Just thinking it might be possible to boost the...

Throttle settings and pedal boost... I was experimenting with throttle settings today (thinking about d8veh's cruise control) and seem to have made an interesting discovery. If you hold the throttle open as well as peddle, it seems that max power is higher than on peddle assist alone :D Not...

How much would one of your 10Ah 36v LiFePO4 batteries be delivered in the UK?

Ah - so are the Kudos ones LiFePO4, do you know? Thought the 36v ones are Li-ion? (I see they do a 24v LiFePO4 drop-in)

@Scottyf: Can you recommend a UK LiFePO4 battery supplier who'll provide a pack which will fit in the standard case?

Bearprint LiFePO4 Cyclamatic compatible batteries... I've been in touch with Bearprint (Bearprint Electric Bikes - Folding, Step Through, City & Sport Electric Bikes) about their 36v 10Ah and 18Ah Cyclamatic compatible drop-in batteries - here's the pricing info: 36v 10amp LiFePO4 type...

DC to DC step up convertors... Have been thinking about a cheaper alternative to buying a 36v battery based on the use of low-cost, high efficiency DC to DC converters... There are some 24 to 36v devices around, but moderately priced examples are rather limited on power, e.g.: Zahn...

Welcome mxer125! I'm a big fan of the thread too - lots of good Cyclamatic-beast-style advice here ;0) Maybe just swap your dad's bike out for a while, do a few mods and then swap it back. He'll suddenly think he's much fitter for sure! :0)

Thanks for the advice - will certainly insist on using Paypal, if I decide to go for it... I have searched all over for a supplier of an alternative equivalent at anything near the price, but no luck. They have been courteous/professional during my dealings with them so far and their marketing...

36v LiFePO4 drop in batteries... A quick update on 36v LiFePO4 drop-in batteries. The one I mentioned earlier in the thread which was labelled as LiFePO4 on eBay turned out to be Li(NiCoMn)O2 (spotted that the cell voltage was wrong, let them know and they updated the listing): eBay - The UK's...

This latching relay from Maplin would probably do the job if you added a zener diode matched to the coil voltage across the coil to limit voltage (+ provide BEMF protection) and a current limiting resistor in series with the signal line in each case: 2A Miniature DPDT Latching Relay : General...

Like the concept - better than my idea, as you don't have to hold the throttle in a particular position to maintain the set-point, which might be problematic... Would be good to find a way to solve this problem... When in cruise mode, how about using a latching relay which is set by...

I suppose that's what i meant by the above really, but using the throttle to set the cruise (while peddling) speed dynamically, as it were. Have you actually implemented a working cruise control :D Does the throttle setting actually effect the output power when peddling (if it's set above...

A slight aside, but strikes me if the throttle set an upper power limit, it would be much more useful than at present - allowing you to both conserve batt life and determine how much energy you need to put in via the pedals, particularly if you're running uprated power. Even with a shunt mod 24v...

Yes, but I want a bike which looks stock while performing well on hills and have several people interested in the same configuration who aren't modders. Being able to simply swap the battery out (and perhaps upgrade the motor controller) seems like the best all-round solution... I have a new...

Yes, but my aim is to get more power / speed / hill climbing ability with stock appearance and the standard battery doesn't have enough grunt.

Would be interested, yes - thanks Barry... Are using it with an otherwise stock setup?

Yep - that one was the only example in that form factor I could find on eBay... LiFePO4 looks a better technology - increased operating temperature range, at least double the lifetime and less prone to early failure, it seems. If I could get one for the same sort of price, think it would be a...
