Thanks for doing this video! It was great to see the process but I can’t help thinking about how short-sighted, even negligent, Trampa was in not full explaining each setting in the software. They spent hundreds, if not thousands, of hours developing the BMS and its firmware. Why not spend an afternoon writing up the explanations? It would significantly decrease tech support calls regarding the settings, reduce user frustration, reduce product damage/malfunction incidents, and increase the appreciation of the community for Trampa products. So frustrating that they made the explanations such an afterthought. Good luck with boxing it all up!
#surfdado Hello, I have a question for you because I have a slight problem with the BMS Trampy, but the one that is in PCB 21700, namely, I downloaded a newer firmware and the BMS icon disappeared where it was displayed, where is the scam? Before the previous update, I had 2 engines and BMS, now I have 2 motors without BMS and the battery status is not displayed and I cannot charge the skateboard. can you advise how to solve it??
haha good point, but I just was impressed by how nice all the parts are - they do sell the 3 layers separately so there's no need to buy the heatsink and top plate if you don't have room for it
Obviously, this bms is great because it is small and slim to fit into the onewheel enclosure, but Daly/HiBoy makes a neat "smart active cell balancer" that is also pretty small. Although it is not a BMS it still has bluetooth and static cell balancing at a very very fast 1.0 amp rate which could keep all the cells in check during the charge cycle as long as you are specifically using a charger set at the perfect pack voltage.
@@surfdado the daly smart balancer has bluetooth so you can see the voltages on your phone using the app. You can check the battery anytime during charge or during the ride!
@@uhjyuff2095 I've had the Daly with the CBCSO - its functionality is certainly better than no insight at all, but who really wants to nerd out and stare at their cell voltages all the time? It gets boring real quick and then you'll stop looking at it... Ideally I want to never have to worry about it and instead get an alert from my VESC app or tiltback from my board if there's a problem
Am I missing something? The link for the BMS shows "This product cannot be purchased on its own.". And I can't find anywhere on their website where I can buy it in any way.
Any reason why you wouldn't want balancing while riding seems like it'd help keep the cells in check during regen especially? Or does it not do active balancing I figured that's what all the giant resistors and heatsink was for.
I'm no expert on this, but every time I look into this topic or talk to experts about it I walk away thinking it's better not to do it. Btw, FM also doesn't balance while you're riding. My best guess is it has something to do with temporary imbalances due to sag when riding hard which would trigger balancing unnecessary and strain the BMS and cause heat buildup
One reason, is you only want the pack to be "top balanced" meaning balanced cells when at or near full charge. If the cell balancing occurs at other than the top charge level then your pack is not quite "top balanced" anymore and it is sort of out of balance when you charge it up again. It is fairly normal for the pack to drift out of balance as the pack is discharged which does mean some cells are stronger than others.
@@uhjyuff2095 I heard about this top balanced thing but I have to say that I have not yet observed this with the high quality cells I’ve been using. Neither my Samsung 25R nor any of my Molicel packs have this behavior- they remain balanced at any voltage
@@surfdado Yeah, you have good cells and are treating them well. Also, its good that you check your packs to make sure they are still balanced at all voltage levels because most riders don't get that involved with their battery packs :)

Love all your VESC content please keep em coming!
I love the "im diffusing a bomb" anxiety lol
I'm hoping you recorded the final product. I want to see it all put together in a short video.

really nicely made bms. good shielding. nice heat sink. im just going to tear all that off because i dont have room }:)

Awesome work mate
Thank you dado!

ehhhhh
that's nice but to me cell balancing is the least important aspect of the BMS

once you remove the space constraint then lots of options open up - but that doesn't help us with our Onewheels I'm afraid
whats the dimensions of PCB?
Am I missing something? The link for the BMS shows "This product cannot be purchased on its own.". And I can't find anywhere on their website where I can buy it in any way.
they have supply chain issues afaik, production BMS is still not available - what I have is a pre-production unit
Sweet
No way you bought the onewheel mat 😅😅
For how many amps is rated?
It’s a charge-only BMS so there’s no amp limits to worry about
Will this BMS be compatible with any of the after market batteries available for onewheels? CBXR or torque pack?
yes, it can be configured for 15s packs
What kind of range are you getting on the 18s2p pack?
about 20 percent more than with my stock XR pack
@@surfdado That is impressive with the 18650 cells. I am considering using the 21600 cells but your latest video is having me re-think the plan.
