Thanks for this. Didn't know about the greedy controller - but I did try deregulating the bike briefly in early days. 1st battery didn't last long. 2nd was much better, then I rebuilt one with new cells in 2014. Has lasted until now - on some pretty demanding Cornish hills. So - probably prepared to have another go........the rest of the bike has lasted pretty well.......

Anyone tried using one of these (Silverfish / X-GO) batteries on the early Ezee bikes? Dimensions look fine - but will need to fit the different 2 pin connector. Not too fussed about the original locking / slide arrangement. Had enough of rebuilding the battery pack...... https://www.amazon.co.uk/dp/B0BQ37PL29 Thanks

Seem to have been successful with replacement BMS. Recharging now working again. Extra sensor came with BMS - have asked for info on where to place it. Guessing it's a temperature sensor. Need a couple of longer rides now to see if everything discharges and recharges ok.

Thanks for this. Was a bit nervous re soldering connections to BMS. But I guess if the jst connector is not connected - there isn't any voltage around. Voltages all ascend ok on the jst connector.

I am about to replace the BMS in my battery. Do I have to completely discharge the battery - somehow ? Thanks -

ok - I am passing this info on in good faith - but I am not taking ANY responsibility! I have recently acquired and fitted the 13Ah version for use with my early eZee Torq and it seems to be ok - so far. Could die on me next week. But they tell me that they are using "high quality" (?!) Samsung cells mentioned above. Have the pdf document on these. http://www.aliexpress.com/item/36V-10Ah-lithium-ion-battery-Free-Shipping/1127600402.html You need to ask them to make the width 68mm to get the pack to fit in the eZee Torq battery pack. This is IMPORTANT if you are to be able to use your existing battery box - ie without having to make any alterations to the battery holder/guides etc on the bike. I don't know about other battery box sizes. There are 10Ah and 13Ah versions - you have to ask for the 13Ah model by special request, and there is a strange way of paying the extra money. Shipping by FedEX is "free" but I was subsequently charged about £18 by UK customs. No idea on warranty / comeback / guarantee etc etc. BUYER BEWARE !! Very quick responses to my technical questions and very neat package. No hesitation in telling me what cells they are using. BUT - I cannot confirm what's inside the pack! It is working with my original Li-ion charger. You will need to be able to dismantle/open your old battery, remove the existing contents and make the connections to the new battery. Significantly lower cost than I can find in the UK - but then there is the old adage that "you pays for what you get" - and I might be in for a sorry surprise. Will post something here if it all goes horribly wrong. Like I said at the start - I am passing this info on in good faith - but be it on your head. The supplier doesn't make ANY claims regarding the use of this item on eZee bikes - they are just advertised as battery packs for electric bikes. Have been mystified that the price of Li-on batteries for cars seems to be coming down, whilst the price for Li-ion bike batteries (in the UK) seems to be going up....

When your cycle battery gets too tired to power your bike - it may still have oodles of life left in it for other applications. I am currently using an old 36V battery pack to store daytime Solar PV generated electrons - to then feed DC domestic lighting at night. ( 3x12V LEDs in series to accept the 36V output). Better than using valuable excess PV electricity to heat water. Just a suggestion...before you bin/re-cycle that expensive battery.

Hi - have had an original eZee Torq for years now and been through several battery offerings. Have recently re-celled my battery box with a pack made up with Samsung Li-Ion cells type ICR18650-26F. The pack is working ok with my original charger - and so far so good. Obviously will not know (cycle) lifetime for a while. Any experience by others with use of this cell in electric bike applications would be of interest. Happy to pass on details of where I obtained the pack from - and battery replacement. Significantly cheaper than current UK offerings.

eZee conversion apologies - I meant Mr Ching. Thanks for your comments flecc- I'll be keeping my eye on the battery and hope that I see a similar improvement in performance - at least in terms of cut-out. At Canadian $750 (see eZee Kits) the eZee kit might be somewhat more "economic" than trading my Torq 1 up to a Torq 2.

Torq Li batteries and Torq 1 > 2 upgrade ? Unfortunately I came to this discussion late. If the race is going ahead - good luck to all - have a great time whenever it is. Two points come to mind - I have been trying to resolve the merits of the Lithium batteries versus NiMH for those of us living in hilly areas. I reiterate - I'm not interested in high speed or long distance - I just need a battery that will deliver reasonable longevity. I am on my second Phylion - I don't have any fancy monitoring gear - but I am logging its performance closely. I do a 2 x 10 mile trip - with a hill in the way in each direction. I am not long into my second battery and am beginning to get in to the amber on the hill after a few dozen trips only. I wait to see if the Phylion can deliver - or whether I should try NiMH or await the outcome of the "new" batteries - I guess they are LiFePEO4 based? The issue being that while the batteries still have considerable "life" in them - once they cut out on a hill - you are worse of than on a normal push bike. Alternatively - I suspect I am suffering "early adopter" issues - at least as far as non-urban users are concerned. I have watched the discussion on "gearing" for a while - whether it be the internal hub motor gearing or the crank to rear sprocket to wheel ratios. It begins to sound to me as though the Torq 2 may offer better gear ratios for those faced with hill climbs. I just wonder if Mr Wong is considering an upgrade path for those of us with Torq 1's ? Something based around the Ezee Kits perhaps ? Will look forward to hearing the outcome of the race .... or should I say endurance test.......will also probably be in the market for a low mileage used battery....

flecc - is this the battery technology that you were referring to in our earlier discussions re NiMh vs Lithium for the ezee Torq ? Will the standard Lithium charger work with this new battery ? Are there any pointers to technical info on this new battery ? Thanks - planetcooler

Hanging on for lithium! ok flecc - I'll hang on in there for a bit longer......in anticipation!

NiMh for eZee Torq? While we wait for the improved Li variants - is there currently a source, anywhere, for (decent) NiMh batteries for the Torq?

Maybe I'll wait a bit Thanks again flecc - very useful - perhaps I'll bide my time and look out for these future developments......(might just wire a reset button up to my handlebars to keep me chugging along....!!)

Moving to NiMh on Torq1 I purchased a Torq in late 2006 with a lithium battery pack. Used it, less frequently than intended, to cycle about 6-7 miles to / from work in Cornwall through 2008 - with a significant hill in both directions. After a lot of inquiries on this site and modifying the front chain wheel - I am presently of the impression that I need to change to a NiMh battery. The degree of cut out that I now get with the Li battery is unacceptable. Currently patiently waiting over 4 months for a NiMh battery from 50cycles - but my patience is getting stretched. Hoping that 50cycles are really going to sort this supply problem out soon. Might ask folk here how one gets through directly to eZee bikes. Given that I will need a new charger, I hope that I am correct - because I could probably buy a new lightweight non-electric push bike with 21 gears on for the price of the battery and charger. Not planning on spending this kind of money every 12 months...Apart from this issue - the bike is superb.....but it's kinda fundamental.....(and yes, before the question comes around again.. I weigh somewhere between 13 and 14 stone - and carry bits and pieces to work in the bike panniers and can - if required pedal a normal push bike to the office if forced to)
