    Yose Power Triangle Battery Recall

    A while back a friend of mine bought a triangle 21Ah battery from Yose Power via eBay. It stopped working and he gave it to me as it was going to cost too much to ship it back. I opened it up and was quite shocked about how badly it was put together, quite a few potentially serious flaws and the...

    BMS Balancing "optional"

    Have you noticed how a lot of BMS devices these days are not even offering a balance option? You have to ask for it as an extra it seems :)

    Front ebike controller powered light recommendation

    The LED inside one of my Yose power kits stopped workng properly last week. It still came on, but very dim. I swapped out the LED module from another kit and the headlamp worked fine. When the LED was pressed on its PCB, it would stop all illumination. So it looks like it was not bonded...

    Checking Multimeter Calibration at Home

    One of the most important tools in an e-biker's toolbox is a multimeter (aka Digital Volt Meter or DVM). It is sometimes needed to be used to measure voltages with a high degree of accuracy, for example looking at the output of a charger to tell if it is set up to the correct voltage or not...

    Daly BMS - a potential cause of battery fires?

    I've heard of some people saying they've had bad experiences with Daly BMS products then recently I came across this over on ES: https://endless-sphere.com/sphere/threads/daly-bms-teardown-failure-review-16s-40a.118344/ It's quite worrying. If what he says is correct for all Daly products then...

    36V Bosch tool battery for e-bike use

    I thought I'd start a thread here for those interested in using 36V Bosch power tool batteries for powering e-bikes. This seems to be of interest for several people on the forum who have Bosch lawn mowers, or other tools and like the idea of being able to use the same batteries on their bikes...

    5A 36V charger, evaluation and modding

    If you have a larger pack (15 Ah or bigger), charging at 2A can take quite a long time. On some occasions this this can be far longer than desirable. So if you need to refill your pack a little quicker, what are the options for doing this in a safe way? 3A chargers are available and I have used...

    Monitoring the Balancing of a Pack

    Been meaning to post this for some time but not got around to it so here goes while I have a moment spare. I think it's worth looking at as the results are quite interesting. I posted this back in November last year: Here is a dismantled Yose power pack, generic Chinese cells, crappy 20A BMS...

    Trailer hitch for e-bikes

    I've recently invested in a trailer to increase load carrying ability, but have run into a snag. The hitch is designed for a 10 mm back axle, whereas with a hub motor, the axle is 12 mm. I've drilled out the hole in the hitch to fit the axle, but then the axle nut is too big to fit in the recess...
