Peruvian Jack

Just had a look at the CPC page and that looks like the connector . At least I can start mooching around now to find the Male version connector for the other end and some cable to possibly make up my own cable. Thank You very much.

Must admit hadn't thought of making my own :-). Cheers

Hello all, I am planning to move my battery to a pannier position and as such need to extend the connector cable. I recently purchased an M12 4 Pin Extension cable but on receipt the actual 4 Pin Connector is too small to connect to my current cable. I have attached a very poor picture of the current connector which is approx (poor eyesight !) 12mm Diameter. Could you please advise what size / name of connector I need ?. Attached Pics are 1) the type of bottle battery I have and 2) the connector I want to extend.Also if anyone could advise of a company / linky to a firm that makes up these cables ?. Thanks for looking

Quick Update, the original seller has still not contacted me, however the electrics seem to have finally come good. Not given the bike extensive testing but appears to be working "normally". So for now I would like to thank all who took the time to read my pleas for help and offer some good advice.

Hi Again ,further update. I did try the battery in another bike and despite being able to properly test ride I did get an expected display on the console and the "walk" assist did work. I returned home and tried the battery again and while on a quick test ride the display suddenly started working and power was being supplied to the motor. Happy days I thought. Test ride again this morning and back to "normal". Battery shows no bars. Motor shows Zero , MPH shows Zero. I have now had contact with the seller who is going to bring me a "new" battery and maybe a "new" controller. As I have indicated previously I can happily "tinker" but know my limits !. Thank you for looking and thanks for the advice so far. I will update once I have tried the new parts.

V.Quick Update. Just tried the battery in another bike and shows 4 bars and the "Walk" assist works fine. Didn't have chance to try a proper test ride but looks like the controller maybe ?.

Thank You both for your prompt replies. No I don't have a multi meter I will check with my family to see if anyone has one or will possibly purchase a cheap one. The battery is removable it slots into the down tube I have attached some pics of the battery . Really appreciate this. Thanks (NB I am also going to try another battery from the same type of bike that should tell me if it is indeed a Battery issue.). I mentioned in my Introduction. I am not electrically minded nor trained !!!, but I will give anything a go. I know my limitations so if it needs an expert to an expert it will go !.

Hi, just a quick hello. I am a new e-bike owner and am a "tinkerer" who knows when to stop and call in the experts. Been having a browse through the site and found it very informative. So more power to your elbow (or should that be motor ?) . I currently have a non working "Longbow" brand e-bike (Grandson's) and am also having another recent purchase Longbow brand bike "converted" by a more knowledgeable person because the battery was no good. Both bikes have 36v 10A batteries. So can't wait to experience the e-bike thrill.

Hello all, new member here looking for some advice / help. Very new to E bikes and I am not am electrician or Electrical Engineer and I wouldn't have a clue how to use a Multi-Meter !!. I purchased an e bike (Branded Longbow) from a Liverpool based site a few months back. My Grandson has had the bike and up until a couple of weeks ago it was working as normal. Then my Grandson said it stopped working !. I now have the bike and it is indeed not working. I have attached a screenshot from another site selling this type of bike and a shot of what I can see on the KT3-LCD controller. The battery shows "green" on the charger and a couple of times on switch on it has shown as 4 bars full on the controller screen. Currently showing as can be seen on screen. The front light turns on Ok. I have reset the controller back to default values, but no power going through to the motor. I have checked the "barrel" connector (9 pin ?) to make sure that is connected OK. Nb Battery is in the down tube. So would appreciate any help / advice. Thanks
