    Battery goes to zero, then back up slowly - bad battery, controller or ?

    I concur... You can't even buy enough name brand cells to make the pack for $115. Definitely low grade cells. Be very careful charging.

    Guys who ride step through bikes...

    ... and I was under the impression that step thru's were for guys with tripod syndrome 🤔 Funny thing is not only am I afflicted with the syndrome, I've got a JXFUKAL bag too. The soft insulated one.

    Installed a Rohloff Speedhub 14, IGH on my mid-drive Luna Z1 Ultra Mag

    Well that sucks. The springs can cause gear slipping so I thought you might get lucky. Yeah let us know about the process and how things go with the 3x3

    Please stop charging ebike batteries overnight!

    That's an understatement. Balancing at lower voltages would be great but realize that you'd be at a higher current point of the charge and this wound cause more heat, especially in the case of a passive balance bms. This could be solved with a matched intelligent charger but additional safety...

    Please stop charging ebike batteries overnight!

    Thing is I'm not sure how many implement the more expensive active balancing.. especially those not of the most expensive brands. Though recently prices are dropping and with the UL regulations being enforced we may see battery builders willing to use higher end components. If you actually...

    Nightly protest bicycle ride in China, by students about their economy, since the U.S. election.

    This is typical of the micro brain that voted in droves. It doesn't take much at all to herd sheep. ps... Zoom in on the photo... No cats or dogs visible anywhere. Think about it....

    Bafang bbsdh as we know it no more?

    In my discussion with GBK... the UART Ultra (and I believe all Bafang motors) are going CANbus only for new motor by years end. GBK told me that UART controllers and associated parts will still be available for quite a while.

    I draw my conclusions and implement best practices based on technical documentation produced by professionals. https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries Not anecdotal observations found on the internet.

    Installed a Rohloff Speedhub 14, IGH on my mid-drive Luna Z1 Ultra Mag

    Good luck, hopefully it's this simple. Saw the 3 x 3 Not sure it would work for me as I like the tighter spacing of the Rohloff gears and being able to dial in the perfect gear. I don't think I ride as aggressive as your counterpart. Also why I prefer a 9 PAS setup on the Ultra.. you can get...

    Please stop charging ebike batteries overnight!

    Though there are more than a few variations to skin this cat... You're observations are the same as mine. The Passive balancing offered by eBike BMS's use resistors to bleed current to keep the full cells from over charging. This happens at the very end of the charge when current has already...

    Please stop charging ebike batteries overnight!

    Not fully charging when unnecessary to accomplish your ride is probably the best thing you can do to keep your battery healthy and safe. I've gone automated!

    $10 DIY Smart Charger Alternative / Ver. 2.0

    Here's the $30 version. Having the same necessity of the momentary contact switch to initiate the charge... I opted for an Off Delay Relay which makes the process automated. This allows me to plug everything in and start a charge by a home automation timer early in the morning or by app while...

    Please stop charging ebike batteries overnight!

    Are you sure about that? I believe what you are witnessing is the basic function of a CC - CV charger/bms. As target voltage is approached, current trails off. I believe if balancing was actually taking place you would see a current increase or remain steady as the target voltage is reached...

    Rohloff Recalibration

    No... Just don't go to work anymore.

    Installed a Rohloff Speedhub 14, IGH on my mid-drive Luna Z1 Ultra Mag

    If the hub is not showing any other issues than randomly slipping I would start with replacing the freewheel springs. Relatively easy to change these $4 parts. Watch the axle ring/plate video as they are located underneath. or

    Best ebike repair stand

    I concur... Lifting these heavy bikes on to a stand is a back breaker. I love my hoist being able to easily lift the drive train to eye level. And then the ability to change height multiple times during a service with ease is the frosting.

    Best ebike repair stand

    Not sure if you require portability... But since purchasing this... I haven't used my older version PCS-9.2 at all. The hoist is much easier to load and lift and the straps give you multiple points to do so from.

    Yamaha Leaving US Market

    Now here's another who has really lost all notions of reality. Quite understandable when their savyior has the vocabulary and mental capacity of a 12 year old. But only a few days to go before we can all get giddy over Arnold Palmer cock stories and our dogs and cats can be let out of the house...
