It's definitely an incredible charger, being able to make as many profiles as you want and set stop charge condition as well as track the Ah and Wh in is amazing, it's small and solid too. I got the 72V version just so I could use it on emoto packs in the future if I so choose. speaking of...

Nice work on the battery pack, lower profile than my 4p and I really need to swap my clear shrink or polyolefin. 0.2mm nickel is plenty if 30A is max pack draw and looks like you managed to get 3 connections between each series group so no hot spots. I welded with 0.1mm nickel strip on top of 5...

Some updates, Grin Satiator got me what I wanted, pack charges about 901Wh from 3V per cell to 4.2V per cell, LVP & HVP work to cutoff the discharge/charge MOSFETs. I tested things out with the JBD BMS and it seemed to work nicely but one thing was when I disconnected my phone from it or shut...

I managed to figure it out - the correct chipset to select and so on. Turns out my bench supply is faulty above 51V or so - not at all happy about that... Got a Satiator and she charges up great. Checked LVP and HVP, get about 45-51 miles on a pack down to nominal voltage and thats with some...

Nice write up. I ordered a set of Mulefut 80's on CM sale for my studded 4.8's so I don't have to deal with sealant or removing the 2XL's on the Nexties. I originally went to build with an EX1 drivetrain but didn't read into as much as I should have, tried to dodge shelling out $3-400 for a...

The wasps don't even sting me once before I sting them. This wild animal is more of a bee keeper any ways. You know the fastest way to kill a wasp? Soapy water knocks em right out of the air. Little bastards don't even get a chance. It's a fine ol solution. Sicarios these days are more like...

I've got an E06 frame and made a custom 14s4p pack of 21700 cells (18Ah but if I use different cell models I can get 20Ah) to use with the X1 - it protrudes a little from the frame but still clears my fork at max compression - the E22/23 frame (Hydra/Hydra Fat) seems like it may have more room...

Yea the front looks super clean. Big benefit of those Magura e-levers and the electronic shifter is the wire is thin and flexible - way more than a shifter cable housing so you can wrap them together right up to the handle. Is the wrap easy enought to remove if you need to get in there? Mine is...

@KevinT WW switched to only offering 48V packs because it's a little easier to build higher capacity packs (extra parallel group buys you way more current overhead than one extra cell in series, meaning lower C-rate on the cells in the pack and thus more energy per cell at the same power draw)...

Battery is a 14s4p made with Lishen LR2170SF's - theyre 4500mAh cells with 13.5A continuous discharge so the pack is 18Ah and good for 54A - but from bench marks I could find that tested the cells from down to 3.2V (so pack voltage 44.8V at empty) at 20A (~1000W) continuous from the pack I...

@Fast n' Furious the T6 just refers to the Das-Kit throttle model, the other option with the wrong plug is C7 - they both use 3-pin Higo's it's just that as far as I understand the T6 version uses a female Higo while the C7 uses a male; the Bafang harness requires a female plug on the throttle...

Nice bike! Glad you stuck it out and got it, sucks that the battery is roughed up. Lemme tell ya I went for my first ride this weekend with my custom pack and was crazy nervous! Had a little paracord insurance tied around the top in case the latch came undone (it didn't). For range expectation...

@Deacon Blues I'm wondering if the difference you are experiencing is one controller the throttle mode is set to current/power and the other is set to speed mode? If you have both bikes have you tried swapping the throttle on each of them to eliminate that being the culprit? Water shouldn't...

Thanks for the responses, So I'm a clown and I expected to be able to activate pedal assist with the bike up on the stand... turns out it needs a liiiiiiittle more force and rotation than what I can manage with the hands... my stock motor was behaving exactly the same and I didn't have the...

I took a ride out over the weekend and bedded my 8.S Magura pads in - at least I think I did them right. Finding enough of a flat stretch around here to get 30kmh then stop isn't easy to do once let alone 30 times... so I opted for riding to the top of my neighborhood and going down, probably...

Ugh... holding down the '-' button kicks it into walk mode and the motor powers successfully... I think I need the programming cable to set it up with the 500C? this is nuts. I just want to ride. Either I swap my stock M620 in or I order a 750C and wait for it and swap that out and hope it...

I finally got things squared away to where I could test my battery and go for a ride - or so I thought. My X1 powers on and I can go through the settings in the display etc etc - but there is no power output when pedaling! I tried taking the bike off the rack and getting on it so there's some...

Icing on the cake is the power supply is only 2 months out of warranty, and I would have caught this issue long ago if I hadn't let myself get sidetracked by all else life has to offer. woe is me, there is no god!

On a hunch I ran some more tests on my supply and seems to have faulty output when set above 50V... I am not happy considering I went with the 60V/15A over the 30V/30A to charge ebike batteries with... works fine below 50V though... I'm returning the DC Load I got of the same brand and spending...

I get lost digging through E-S. So far I have not found any threads regarding a BMS causing weird issues with a bench supply. It's as if the BMS is trying to discharge into the power supply but... this doesn't explain why it's only going up to 17.5~17.7V and I would imagine this expensive bench...
