As per the title. Any one using a UART BMS in their battery build ?

I noticed this neat little 30mm dia tube controller also a Kt rated at 12a and dual voltage. http://www.topbikekit.com/10s13s-36v48v12a-yg-kt-6mosfets-sine-wave-controller-kt-tubular-controller-p-1039.html It is a candidate for a seat tube conversion to hide it in or a modified seat tube...

I was going to put this under the 'Conversion kits heading' but decided this heading as it is a cargo bike. My Kona Ute has been waiting for conversion and still is. The Ute in Burgundy finish. This arrived today well packaged up, 10 days from ordering. Opened up to find!!! Supposedly 48v...

An extracyle rear end kit is on ebay at the mo for £200, an ideal cheap option to make up a longtail cargo bike for extra carrying duties. Convert practically most bikes with a std rear 9mm drop out, the extrcycle rear uses a 26" wheel. One would need to extend the rear brake and fit a longer...

A thread that some may find useful, so do please add you own trailer pics here. My old Norco now decommissioned as the seat post weld snapped. The trailer is a Carry Freedom Y large model, I chose this one for the 90kg/200lb max payload.

It has been some two years or more now since Tony aka anotherkiwi has graced these pages with his experience and knowledge. Having moved from uprights to trikes he then developed a passion to build a Velomobile so jumped ship to a more specific forum or two, one in Germany and one in France...

My latest creation is the Alfine 8 hub geared Cotic Roadrat with G370 front mini hub motor, pleasingly the hub rides not that far off an unpowered bike thanks to the much lower internal motor gearing. This means riding above the 15.5mph is quite easy, to better improve range I have taken the...

New edition the household called Tigger, been here 11 days and is well an truly made himself at home. To those who know about cats he is a rarity and genetic freak of nature. Though he is just a short haired moggy, the White on him gives him away as not just a Tortoiseshell but one with a big...

Those using a Yamaha PW motor/battery combo can now save few quid by using a third party battery on the bike. A dongle has been designed to hack the system to use said third party battery. Although CANbus isn't used the motor/battery still use comms between each other and the charger. Battery...

Kudos bikes aka Raleigh Design have an ebike offer on at the mo. The Rapide commuter model is £1195 and is now on offer at£1695 for two.

Any one using one ? If so do the buttons works ok or do I just have an awkward one ? I like the minimalist look of it on the bars and it has all the features of it's big brother the LCD3, my only quibble with my one is the down button isn't too user friendly and one has to press it in a...

Over the past 6 months I have been looking for a better load lugging bike that has much more cargo appeal then the usual bike. Just a few bikes I have been looking at. Kona Ute no more in production it appears though I did manage to buy an immaculate 2020 example this week via ebay, a rearward...

Can anyone tell me the available parameters viewable on the screen, for instance does it have a voltage readout like the KT lcd3 ?

Panasonic are to begin testing of their new Tesla developed 4680 cell, reported as costing 50% less then current cells with 5 x capacity increase. As with some Tesla cells using lifpo4 tech no plans as of yet to follow with the new cell format. Production is set for 2022 if results are good...

What do you do with yours ? Recycle them at the tip, use the cells for torch's or re- purpose them for other uses? In the past I have deconstructed them to make up smaller 12v packs for other uses. My latest use is to leave my 7 year old 14.5ah Dolphin case batteries as they are and have...

Forum posters come and go but some who were quite prolific or regulars just disappear off the scene. Eddie PJ what ever happened to him, we know he became a product reviewer for one of the big emtb brands but just quietly disappeared. KirstinS suddenly just dropped off the scene. Tony aka...

PswPower/Elifebike and Elifeshop on ebay pretty sure both are related or owned by Elifebike are both selling MXUS front kits and rear cassette kits with and without batteries, all with the excellent KT electronics and wound for 270rpm. Posting is from Germany. This gives buyers another option...

After I posted about finding my 974wh PF celled battery had failed yesterday, I went on to mention other cells and about fake cells due to the very low current supply of quality branded cells. So though it might be good that we have a dedicated thread on Fake cells and possibly what to look out...

As some may be aware I am true diyer and that includes batteries , well today I had to virtually bin a 974wh PF soft pack (a decent size being 7p 13s). As with all my batt's I check on a 4 - 6 week cycle to see that nothing untoward is occurring, this one only being checked some 4 weeks ago...
