On the other hand, you could move the battery forward and make the bike more balanced. The original design is going to be more robust, with better seals at the connections, if nothing else. Rebuilding the pack would make more sense than chasing stuff on Alibaba. You can't recreate those monitoring connections. If the original battery pack has more than the plus/minus connections, stop there. If you run the wires to the original connections, leaving everything else in place (circuit boards, etc) it should work. You can mount his batteries in a bag on the top tube. In other words, one could buy a battery from Paul at EM3ev. The answer to that is 'Yes, that will work', as long as the polarity is right and the voltage is right, and the electronics will integrate with the new battery. I think the OP was asking if there is any reason he can't put a different battery into the connections on his bike and ride off into the sunset. I was surprised how easy it was, really, assuming you can make a good connection to the existing plus and minus, etc. I just tested this out after making a pack for a bike I am building. A custom frame build would be much more of a problem. That means any battery you could safely and securely attach might work, which is good. It looks like your bike is like mine, with a rear rack. I don't know what you want to do for a case and how things would fit together. Beyond this, the charging would be completely separate and you would probably need another charger. The circuit board you see is probably to monitor the voltage and turn off the power if the voltage drops or other bad things happen.Ĭlearly, the connection on my bike is two wires, so it's hard to see what could go wrong. From here I can hook up my bike to another battery, which I moved to the front. Well, I've done this, which is basically jumping the two connections (plus and minus) with the proper connectors.
