    Ebike Battery Pack Repair Help

    I couldn't because the probes are too big and won't fit in the connector. Okay, I measured everything again. The whole pack reads 31.47V. See the video for the individual cell Vs. The plan is to remove the two bad sets and 1 set at 3.4V. I'll replace the bad ones and charge the 3.4v up to...

    Ebike Battery Pack Repair Help

    Hey Amber! I took a few more readings. The image's top left cells are dead and need to be replaced. Gunna be difficult cause the paper casing is glued together pretty solidly. The Cells are 18650, so I'll find replacements with the same voltage/amp. Questions: 1. Do I need to remove the 3.4V...

    Hello, I am looking for some help diagnosing my battery pack which has been sitting around for a few years in my garage. I am looking to see if it is still usable as the bike is still basically brand new but doesn't charge. I wanna start off with the fact that my understanding is beginner...

    36V 9A Battery Over Discharged help!

    Thank you for the help again. How is this exactly accomplished with the Hyperion? I have two Anderson connectors attached to the Hyperion. Would i need to dissemble the pack to charge each series? I am assuming i would use the contact points on the Hyperion on the top and bottom of each series...

    I am going to do that for sure. Has the issue of overheat cut off been fixed? also has the BBS02 been transitioned over to torque sensor yet?

    Best Kit for Installation Business

    Hmm, is the tinkering because they want to tweak it to go faster or is it due to the system always needing tuning? 90% of the people interested are people who want to save on back and forth to work. Here in Toronto, parking is about $25 a day in downtown combined with traffic, gas, etc it cost...

    Best Kit for Installation Business

    That is a good point you have about the warranty. However I would most likely tweak it to 2 years on service and 1 year on parts for the E-Bike Kit as long as it is not abused (dinged up, scratched badly due to negligence of use) and no warranty on the battery since customer use greatly affects...

    3D Printed Custom Infineon Controller Case/Enclosure

    I can understand still that Omega build would be difficult without adequate heat sinking. i would need to use some type of metal channel inside to disperse the head without it heating up the surrounding. For now i will concentrate of Alpha. Seems like the better bet having some type of skeletal...

    3D Printed Custom Infineon Controller Case/Enclosure

    So i took what you said into consideration and modified the the Case to be almost like a harness. I added a cooling vent to the top of the frame as that will be where most of the dispersed heat will be. As for the mosfets on the side, i have opened up the sides so that no Plastic will be in...

    3D Printed Custom Infineon Controller Case/Enclosure

    I take it that the case in its entirety will not hit 200 as mine has never gone anything near over 40 C yet. I can see that the Mosfets used thermal paste like processors do on a computer where the heat sink meets the case. If that is the case i will have to go with Alpha as to incorporate the...
