There are not that many cyclists with Orbea bikes. I do not know how they implemented the CANbus. I have few prospective customers waiting for their bikes to arrive. I have successfully connected two Li-ion batteries in parallel uneven capacity, fully charged, same voltage via shorting switch. It works well. As they discharge the balance each other. For charging I disconnect them and charge them from one charger via schotky diodes. Doddle, works treat. Perhaps we can tap the built-in battery directly, ignore the CANbus and do my little parallel trick.

Hi Capt, There are three possible variations, approximately: 36V 5.8Ah £125, 6.9Ah £175, 8.5Ah £270 with the phone charger.

I am the guy mentioned above. Willcee, lot of praise, I am blushing, thank you very much. I wish you many happy rides on your new battery. But to the point. I can make the bottle type battery, I am looking into it. It's a bit tricky, but I can make 6.9Ah in a PVC tube 68mm dia x 210mm long including BMS and charging port. That could fit nicely into the bottle holder. Would there be interest in phone charging socket??? The only question is connection to the bike's proprietary connector and interface. I believe they use CANbus, and connecting two batteries to power the bike is not that simple. They can be connected in parallel, if they are very similar, same voltage, age, cycles etc. Or they can be used as main and spare. The benefit of using them in parallel is running them at lower C which means getting more capacity out of them. I am going to use two batteries on my bike with a switch, which has got two positions. Run and charge. In "run" position they are connected in parallelel, in "charge" they are separated and charged from one charger via Schottky diodes. If there is someone, who could shed some light on the Orbea barttery management, please raise your voice.

OK, please do that.

Your existing battery is 260x93x61mm. Is there space for 70mm instead of 61mm? If yes, than I can make 36V 18650 battery 10S5P with excellent Panasonic cells and BMS with 15.5Ah capacity. Cost £265.

Hi, I can rebuild battery, I am in Stanmore, HA7. What cell configuration do you have? Interesting bike, any chance of a link to seller? Thanks!
