Re: DIY assembly kit for 18650 without spot welding/Soldering

Hey Guys, @esust I have attached your battery pack pic on your behalf. There is a bit of a size limit here. Thank you for the kind words. I do agree that one batch was not upto the mark but the bright side is that it made us up our game. Infact every problem we face, we try to analyse it and really ...

Re: DIY assembly kit for 18650 without spot welding/Soldering

Hey Guys, Sorry for taking a while to reply. If by UV you mean regular sunlight then yeah, the new caps are far more stronger and robust. What we do is leave them out in the sun on the roof of our shop. Our workshop is in India so we receive plenty of sun all year long. As for pricing and officially...

On top of that a bot has been making things worse for us by flooding our mails with plenty of mails. Our mails are vruzend(at)gmail(dot)com and contact(at)vr...

Re: DIY assembly kit for 18650 without spot welding/Soldering

Hey Parabellum, We are actually using a mix of few polymers. The Vicat is at about 125C. Reason for using a mix is to achieve the desired smoothness softness and yet maintain high tensile strength. Also it prevents the caps from going hard over prolonged usage. One more thing, polymers have a glass ...

Hey Guys, Sorry to keep all of you waiting this long. We are very close, and expect to be ready to debut the V2 in a matter of weeks. We have been working tirelessly on the V2. There have been a lot of changes that we have brought about. The caps have been re-designed, and the physical shape is simi...

Re: DIY assembly kit for 18650 without spot welding/Soldering

When 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...

Re: DIY assembly kit for 18650 without spot welding/Soldering

The more it came apart, the more difficult it became to get off in piece. 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 o...

Re: DIY assembly kit for 18650 without spot welding/Solderin

Actually that's what i first thought but vuzend said it would be harder to attach them with cells What I meant was Sir, that be a bit careful when doing the series parallel connections. Triangle pack is a bit tricky compared to a regular rectangular pack. As for placing the pack on to the cells you...

Re: DIY assembly kit for 18650 without spot welding/Solderin

I'm going to drill and counter sink posts so pack can be bolted together. On second thought, there seems to be the risk here that if clamping is performed in the middle from bolts like this, the caps around the outside can be forced up and loose contact, like a lever arm being pushed down on one si...

Hello all...newbie here. I am currently in the process/talks with Urvakhsha about stocking these for USA resale. I have added the kits to our website. (We are in Maryland) However, I am a newb and I am sure I am not allowed to push sales of products or links. So I'll just leave it at that, unless a...

A simple 10s 4p set up would cost about $260 or 210 sterling in total with GA cells.

Re: DIY assembly kit for 18650 without spot welding/Solderin

Im interested in how many amps a 20s 4p setup can handle with high quality cells. I see these as mid level options like 40amps. But how about 80amps ? Who going to test the limits ? I had made two packs of 13s4p each. LG HE2 cells. Connected the 2 packs in parallel. That makes it 160 Amps. It worke...

Re: DIY assembly kit for 18650 without spot welding/Solderin

Looks like a solid product so far. Once the packs are assembled, and then hammered together for a very tight friction fit , how difficult is it, to get the packs apart ? Just wondering if it is a bit difficult , maybe there could be a improvement on that end of the spectrum if a person needs to dis...

I bought some of these to build a prototype for a larger stationary power source. They’re pretty good! Solid, quality components. The pack on the left is 12V, 3S6P balanced. The one the right is 1S28P that I use for a 5V supply. Make sure they are at least partially seated before you pound them. Yo...
