    New Samsung cell 33G

    I have the 14S9P triangle pack from EM3EV, with 33G cells inside. At least that is what I ordered; I haven't dared pull the pack apart to actually check. :) My setup is a BBS02, derated to 18A, so not a high power setup by ES standards. My daily commute is 30 km each way, i.e., 60 km roundtrip...

    Critique this 3D Printed Battery - 14S10P 29E

    Just had the middle section printed. Images (cells are 18650): https://goo.gl/photos/ArRC8UpAtrmSJg8g8 On the last picture, notice the threaded nut that fits (very tightly) into the center hole. Bolts with countersunk heads will go through the side plates into this nut from either side, which...

    Critique this 3D Printed Battery - 14S10P 29E

    @ScooterMan101 I don't disagree with that, but I'm not really at risk since I don't own a 3D printer. I just use online services such as 3dhubs. Usually, there is local provider who is not that expensive. Similarly for laser cutting.

    Critique this 3D Printed Battery - 14S10P 29E

    @Skrzypas thank you for your suggestions. I finally decided that I really value a no-nonsense battery in day-to-day operations. Hence I decided to go with a BMS and satiator. BMS will be the tinyBMS from circuit, the 30A cont' version. (My max controller max current is currently 18A, so plenty...

    Critique this 3D Printed Battery - 14S10P 29E

    @whereswally606: The Graupner Polaron Pro looks like it fits the bill. However, buying a high-quality BMS (e.g. TinyBMS from circuit on here) + cycle satiator is cheaper, and will be less of a hassle in day-to-day operations. Hmm. I guess TinyBMS + satiator will be my way...

    Critique this 3D Printed Battery - 14S10P 29E

    Hi all Long time lurker; been reading on here for more than 4 years now. As such, I find that it is reasonable now to start on the battery building adventure. :) I plan on doing a 14S10P build for my ebike commuter. I recently (10 months ago) switched jobs, which extended my commute a fair...

    Bewo, New Crank-drive Motor

    Thank you for the reply, but I am a bit disappointed. The BBS01 also has a metal-metal gear, so I hoped that the sine-wave controller would make it noticeable less loud. The quest for a silent mid-drive continues...

    Bewo, New Crank-drive Motor

    Great info. Could you compare the bbs01 and bewo kit a bit more? In particular, I would like to know whether the bewo kit is more silent than the bbs01. My bbs01 has a distinct whine from the engine when it runs at 80 RPM. I would guess that bewo does not have this, in especially when using a...

    BBS0X - Assembly order of bottom bracket

    Hello all I am the happy owner of a BBS01 middrive unit. So far the drive have pushed me 2400 km, without too many problems. However, I have the issue below that, after several hours of searching through this forum, I cannot find answered anywhere. My problem is that I took the bottom bracket...
