That's my Santa Cruz in the clip, and this battery format made for a super easy fit that just did not work with other common pack types. Works fantastic!
1) That was a fantastically put together video. 2) A+ battery construction. 3) Giving away the files for free? Hell yeah! My only criticism: I've had several Daly bms' and I don't believe for a nano second that their "30A" bms can withstand half of what that battery pack can output.
Thank you for an excellent comment 👌👍🙏 We do load test these at 30A and they barely get warm, but you're definitely right in that the cells handle WAY more than the BMS. This was simply the most BMS we could fit into the small space 😁
cheers guys, i tested their BMS before. no way they will hold that current for long time. is gonna fail sooner or later. and they are saying the "equipment isnt enough to change to 12AWG is straight up a lie. i do love the battery case!
We ran on the bench at 30A and the BMS only gets slightly warm. That being said I wouldn't try to push it. You probably did not test this BMS as it was custom made for us, and they do not sell it openly. It was a modified version that stuffed a couple extra fets into the board. Otherwise it is a 20A rated BMS.
@@ElectricBikeLaboratory i am living in china and know the factory boss from daly BMS. in dongguan right? i am living in dongguan too by the way. i had 300 amp custom made BMS. they didnt even hold 150 amps. huge pain. just be careful guys. if you need a contact localy to check stuff you can ask me since i am going to all these factorys regular for my projects. i like what you do! our engineering minds are alike 😊
@@ElectricBikeLaboratory no worries. i dont want any payment or something. just make sure you dont think i try to sell you stuff. i just love doing these electric project. 10 years ago i build 50kw electric scooters.
We still have to revisit the dual motor bike. Well hopefully have a couple more dual motor videos coming up in the future and definitely will be exploring the vesc
Thanks for the video. Which filament type did you print the case with (PETG, ABS etc)? Also can you provide a link to the glue gun and black glue stick you use in the video? I like the way you use this for insulating some of your soldered connections.
Hey there thank you for the comment ! We actually use a special type of PLA manufactured in Canada called PLA Pro from filaments.ca it is a UV rated and temperature resistant PLA (a bit expensive but great stuff). Glue stick wise we actually just use "black hot melt glue" off Amazon. Thank you for the comment !! 😊👍
Yes we have several videos on those as well. The "slimmest" battery I'm aware of is the Hailing G56 which is still 96mm height. This is almost half of that height, hence "Slim Pack". There are many, many battery styles out there for different use cases.
i cannot understand why you put the temp sensor at the top when most of the heat will be generated towards the centre total madness, iv been building ebike bateries for years and would never put the sensor there its total madness
52V 20ah makes me want to build another bike just for it!!!! Awesome job guys. I’m loving the 52v 13ah that you guys built for my current bike.
as a novice at this that build looks really clean and safe.
Thank you! 🙏

Woah it didn't occur to me that this was possible!

Great job guys, and great video.
Thank you very much sir! :)

Nice wiring
Thanks
Amazing!!!
did you guys ever make that dual motor vesc ebike?
We still have to revisit the dual motor bike. Well hopefully have a couple more dual motor videos coming up in the future and definitely will be exploring the vesc
awesome. Looking forward to it!@@ElectricBikeLaboratory
Can you guys ship to the uk ?
What liability insurance do you have?

So on a hot day the PLA doesn't melt? Would be my last choice actually..
This is what I need, I think, can you please tell me the physical dimensions of the pack, I have limited space 👍
Check the site where the files are, dimensions are there too 👌😁
@@ElectricBikeLaboratory thank you
So...where is the 3D printed battery?
how much Amper that bms in peak? sells 60-80Amps but bms? i build and drive 14S2P!
The BMS is 30A continuous and cuts off at 90A
Have a look at “down tube” style bike batteries. They are extremely ubiquitous and cheaply available.
Yes we have several videos on those as well. The "slimmest" battery I'm aware of is the Hailing G56 which is still 96mm height. This is almost half of that height, hence "Slim Pack". There are many, many battery styles out there for different use cases.
@@ElectricBikeLaboratory ShanShan supply batteries and cases down to 33mm thick.
Can you provide a link for me please ? Would love to check it out 😊
The slim rear rack batteries like from bosvh or shimano also seem quite slim

Because he is an amateur. He doesn't know what he's doing. This is why.
Why don't you check the internal resistance of the cells before installation, only the voltage? It makes no sense to check the voltage itself.
