    KT controller upgrade - throttle works but no PAS

    Test the PAS wiring for any fault , make sure you are seeing approx. 4.4 - 5v on the 5v and then it switching off on the signal wire. You will have to remind us again which PAS is in use. I have only had one issue with PAS and that was a cheap non KT unit I bought off ebay many years ago and...

    Prices of the electricity we use to charge

    Wow , 160 & 480, you two must be using a lot of power gadgets. My last dual fuel bill was £88. CH is on sometimes for 2 hrs morning and again the same in the later evening, during the day if too chily the open fire is lit with wood . The cargo bike /trailer is ideal for collecting fallen wood...

    KT controller upgrade - throttle works but no PAS

    I use KT all the time with very minor issues (two in 8 years) , generally the system isn't garbage. One of my issues was the lcd4 which I liked for it's minimalist features, but also had minor issues with mine. I swapped it out and refitted one of my lcd3 displays and the issue went away...

    Help! Stabilisers for Adult Ebike

    The addbike is much like the TReGo that PeterC had on a couple of bikes , the tilt I doubt will be of much concern as it simply aids the bike in making turns easier rather then a upright stance that a traditional rigid trike uses. The latter often being a concern for stability on turning.

    Battery life

    A small EV running on 48v, one would use those EVE LFP modules the 280ah ones would make a 14kwh battery for £2250 + bms or the 105ah for 5kwh /£950 +bms.

    I can mitigate some of the green rubbish by one day having a large green bin for fortnightly collections though a small fee p.a is charged for the service I shall wait until I have no car and no motoring expenses then I will be a little better off.

    Battery life

    My personal car use is typically only 500 - 700 miles p.a, as noted on the forum I'm prominantly a cycle user only so either panniers front and rear or oversize panniers on a cargo bike , the CF 100kg load trailer can do most of my needs. It's just bulk that is the issue such as visits to the...

    Battery care question

    Just keep things simple charge indoors some where above freezing.

    Battery care question

    Yes they basically encompass all can cell types in use today, Cobalt or manganese being a main part of the cathode or annode. It matters not whether ICR, IMR, NMC or NCA they all in general amount t to the same. Using differing acronyms is just splitting the hairs.

    Battery life

    Personal people transportation will likely still be available though thru micro cars or the quadricycle route , cost wise though they will be like the AMI 7 -10k each and limited in size and range . Just enough for two people and local transport. The expenesive cars may be unsustainable for...

    Another cell over rated and nowhere near the specs , 5500mah max it seems if one is lucky.

    They are prismatic so basically a soft cell pack, the casing is only thin ali sheet. Poor grade or fakes will swell also as they warm the sides can expand ,bow a little . Keeping under light compression is recommended. They are popular for diy solar use and camper van use , quite a lot of films...

    Battery life

    One can't mix battery chemistries, those Eve prismatic cells have to be clamped/compressed together to prevent them expanding . They are more suited for a static solar use or a larger static positioned ev use. For bike use just too heavy and at 105ah way too much capacity a 48v LFP would be...

    One would chang lvc & hvc, typically for 80% DOD for a 36v set up would be 33.6v & 40.2 v. 90% DOD approx. 36v & 41v .

    Battery life

    Another thing with LFP one can't really go by voltage regarding discharge as the curve is very linear and typically only 0.35v for full to empty on single cell basis, one would need to monitor Wh usage to be more exact so a shunt / watt meter incorparated. DOD of 80 % or 90% for best cycle...

    New to electric bikes - advice

    Sine wave means a quieter electrical system vs square wave, the former smooths out the frequency signal fo better efficency.

    I think partially that is what we see in the used ebike market for mid drive bikes SW, quite a few up for sale before the 2 yr warranty expires except sellerswant top lolly for a worthless bike that is likely to be scrap should it go wrong soon after.

    Ten of Top LFP manufacturers are china companies. CATL. LG chem china. Lishen (tianjin). BAK. Eve. Are the five some of us may of heard of, the others being. BYD. Guoxuan. Desay. AVIC. Funeng. The drive away from LFP was driven by higher density & lighter lithium cells but now with...

    With the differing chemistry one has to remember the series count differs. For LFP 24v becomes 8s & not 7s. 36v becomes 12s & not 10s. 44v becomes 14s & not 12s . 48v becomes 16s & not 13s. Though if one was using cells like the 32700 one could technically use 15 cells in series for an exact...
