Some comments from someone who has built battery packs for the last 7 years..When picking and matching cells, you look for the resistance of each cell and ones that are out of the average resistance of your cells should be avoided. Even in grade A cells, resistance will not be the same across each cell, although they should be very close, thats why I always get extra cells before I build. Second, there is no shortcut to heaven...and there is a reason why cells are either Welded with nickle strip or soldered. Its called AMPS. The more amps being pulled the tighter the connection needs to be to the point that it requires much more that that board could provide..while this would be fine pulling very little amps (perhaps 10 amps), trying to use this in an ebike application pulling 50-80 amps would be a fail.
for doing batteries for 7 years you could have been a little more specific. with 40t cells you can draw close to the amps you say would be fail in total. are you saying they did a design mistake and you burn the circuitboard when you draw this much?
I have had multiple of these packs pulling crazy amps, one of my boards is a 4x4, I even travelled overseas via air with my board and just ordered new batteries and dropped them in. on arrival. The pack is crazy robust and no limitation if not better than welded packs that have a finite lifespan and if one cell is stuffed you end up with a major pack rebuild. For eskate this is the best product available in my view.
Hi So I bought the board with this battery and paid for installation for it as well. I am having trouble charging board. Battery is not getting charge. I can't turn board on at all. So far board is not usable ever since I got it. What should I do?
When i purchase a full board with the 21700 Monster box option will all the stuff in this video be included ? (apart from the cells of cousre, i live in germany so i cant purchase a ready made battery from you it seems) Or do i need to buy the other electronics for the battery seperately
Will the trampa wand work with a flipsky 4.20 dual vesc? Also does anyone know if you can put a vesc in a halo 2.0 carbon or any other name brand boards? Thanks for the videos!!
Quality kit guys I wish there was something like this available for 12s8p that would make my life so much easier

@@boredCoy Rubbish and bullshite
can you do a 14S 6P with this set up?
And would you ever consider making orientations for 16 18 and 20S?
Bonjour,
Je vais faire un 16s6p avec les 21700 auriez-vous ceci s'il vous plaît ?
How long before you get these back in stock? Cheers
god i love that uk mashup drum n bass

Hey man, send an email to support@trampaboards.com
So Vruzend and Jehu PCB's had a baby...interesting.

Yes, if you select the 21700 pack when you configur a board; you will get everything needed (as shown in the video). Apart from Dave and the tools!
Nice design! Is that part touching battery custom? Where I can buy it?
could you use standard 12s lipos
Yes you can!
when i connect the monster box to the dual vesc i hear a 2 bob 😳 why is that please help me
If the XT90 connector is not an anti spark version, then it will sometimes pop when connected. This is normal.

Hello, it might work, but we can't say for sure as we have not tried it.
