I've never done it, but it seems like you could use a couple pieces of wood like pry bars with a 3rd piece between them to get the right spacing, then pry them apart along the edges.
They are a mixture of new, old stock batteries. Not sure how that info will help though.
Also, I would like to add that I had a single strip of the blocks that I thought I could use to charge a bunch of cells all at once by placing them in a single series. When I pulled them apart, all the blocks came apart as well since they could only be pulled out one at a time. They were all still connected by the metal tabs, but the plastic links all came apart. They are just too tight to get apart all in one piece as far as I can tell.
Not the best picture, but hope you get the idea. Instead of using a piece of wood between the two levers, it would be better to use a long threaded bolt with nuts on the inside so you can easily adjust the width. Just pry a little at a time and work your way around the edge, then repeat.

I was just trying to remove one side, but since it is all flexible, it didn't hold up. Cells from the bottom popped out instead of the top and then the clamping force of the bottom caps was compromised. Here are some photos of the process/disaster:
Hello Sir,macribs wrote: ↑Nov 26, 2017 3:26 pmWhen launched there was some talk about a version with different bus bars then stainless steel for increased current handling abilities. Is that a done deal by now? I noticed a while back they got plus and minus caps color coded, but I forgot all about this thread until now. What is the max current people draw from these batteries now?
I would really like to see someone demonstrate these methods. I basically did what is described in the first suggestion other than undoing the connections. I figured it would be easier to come off all in one piece if the connections were holding it together.VRUZEND wrote: ↑Nov 27, 2017 7:24 am
The simplest way would be to undo the connections from one side for the part that needs replacing. Pass in a flat wooden stick and leverage it upward. While doing this keep the pack flat on a hard surface so that the other side does not come off as shown in the pics. (Keep the bus bars on the other side on) Start from one corner of the pack and do this skipping 2 columns. Do it gently a couple of times and the top will come off.
You could undo the connections on both for just one column from where the pack needs seperating. Place the pack at the edge of your work bench with the part that needs replacing sticking out. Hit with the butt of your palm and that part will slide off and separate itself from the pack. Or just lay the pack on its side, hold it firm with one hand and slide the part out Or just gently tap on the cap legs with a wooden mallet and it will slide off. Just undo the busbars on both the sides for this. The only bus bars that you would need to undo is for one column from where you need the pack to slide off. Once it slides off opening and re-assembling a smaller part is easier and a lot less messier and time consuming.

The FAQ section does address a host of commonly asked questions.
Just let us know if there is anything else.
I'd expect a higher potential for a problem pack with a "mixture". Although you don't describe what mixture means. Very early on I had problems mixing cells of differing Mah.
I'd suggest that this wasn't the right choice of systems for a "massive triangle pack". I'd email Micah Toll for an assist. mlt34 here and ebike school website also through Vruszend website.DasDouble wrote: ↑Jan 12, 2018 5:58 pmGuys, Im having so much freaking trouble with a f*cking pack I have built with the VRUZEND kit, could you please help me out? So I have built that massive triangle pack for a friend of mine and the thing is that always some cell groups go to a really high voltage from like 3.48v to 3.5v in seconds when charging, while others still stay at around 3.48 - 3.49v per cell. What do I wrong? Is it that some cells just don´t have any contact to the whole kit? Its so freaking annoying - I hate this so much. Please, could someone help me with that?
