that sounds like its probably be the reason as I think I didnt turn the battery on also thankfully I only probed the outer contacts as I knew they were the terminals even so there is still the possible issue of lack of capacity

How does the capacity of the re-cell compare to the old battery ? The company that did the recelling said the capacity would increase from 11AH to 13.4AH but given how depleted the recelled battery got after the first bike ride when compared to the original capacity of the original (brand new) battery we cannot see how thats possible for example when new my mother said the original battery didnt go below around 40% on any of her rides but on this first ride on the recelled battery it went down to 24% & that was with some of the trip on eco mode which she never used with the old battery Obviously the bike itself is a few years older now so possibly that might have some affect on the power drain Do you know what cells were used in the old battery and the re-cell ? the old batteries were Samsung INR18650-29E - 40 of them we were told the new batteries would be Panasonic/Sanyo NCR18650BL Have you been conned if not a reputable company and actually still have the same old cells in the battery ? the batteries were definately replaced as they sent the old cells back to us - we used a company recommended on this forum i.e. eBikebatteries.co.uk The company only accepted payment by either bank transfer or paypal "friends & family" so if there is an issue as appears to be the case then we are completely at their mercy as to whether they will address the problem or not Ive asked my mother to monitor her next few rides to see if theres any improvement

My mother recently had a bike battery recelled for her Crossfire ebike She has since taken the bike out to test the recelled battery & has been a bit disappointed by how quickly the battery seemed to deplete compared to the performance of the original battery when it was new i.e. the performance does not seem that much better than the old worn out battery She had fully recharged the battery a couple of days ago straight after the bike ride Today I decided to test the voltage at the outlet connectors & found it was only registering 21 volts I put the battery back on its charger & about 15 minutes later the charger went green so I disconnected it & rechecked the voltage which was now showing what I believe is the expected 42 volts Does anyone know why the battery would only show 21 volts only a couple of days after a full charge e.g. are the new batteries duds ? - or is there some other explaination ?

there does appear to be reshippers that will handle batteries for a reasonable cost e.g. https://mygermany.com/shipping-cost-calculator/ but you have to add on the import taxes to that too so it starts to become fairly expensive - possibly close to £100 of extra costs so if I bought the ebay battery linked too above & had it reshipped its probably close to £300 in total assuming everything went smoothly I also got a qoute for recelling that was £375 (with increase capacity) so I need to decide which option I prefer - currently I am thinking pay for the recell as it seems the simpler option with less to go wrong -the company in question has mostly good reviews i.e. https://uk.trustpilot.com/review/www.insatinternational.com?stars=1&stars=5 its rather frustrating though with yosepower selling the battery for £192 on ebay which is almost half the cost of recelling does anybody know if it would be possible to disconnect the existing battery & use a completely different battery with the same voltage / current ? - will the smart BMS cause problems ? - if so what that would entail from a DIY point of view

this may not be the forum for this but does anyone know of a good value reliable reshipping company that ships from Germany to the UK ? yosepower now only ship a subset of their batteries to the UK that they stock in their UK warehouse & this battery is not one of them I was looking at this battery at least a year ago and am regretting not buying it then now

yes I found that - doesnt ship to the UK again

when you try to checkout on their own website the online ordering system will not accept a UK shipping address - feel free to try a dummy order to confirm this for yourself also like I mentioned they sent me a message about the amazon order specifically saying they canot ship from germany - they can only send batteries they have in their UK warehouse I assume this is brexit related ?

After looking through this forum I found that this yosepower battery would work as a replacement https://yosepower.com/products/downtube-36v-ebike-battery however they do not ship to the UK now (I assume they might have done in the past ?) So I tried to order it from the same company via Amazon germany which allowed a UK shipping address https://www.amazon.de/-/en/Battery-Electric-Bicycle-Charger-Phylion/dp/B096FCWDN6 However I have received a message saying that cannot ship from Germany & do not have it in their UK warehouse ANyone know how I can get hold of one of these ? - preferably without the added cost of a reshipping company like shipto thanks
