Re: What's the current gamut of solderless/weldless 18650 battery pack construction?

I have 3 kits, NESE, VRUZEND, AND THAT GOOF WITH THE MAGNETS. VRUZEND work well, especially the latest release. NESE are nice too. I have a 7s3p Vruzend original that has worked well from day one. Pictured before BMS. (Clear cell sleeves) I dont think i saw your NESE pack built. If i can remember c...

Re: 2020/21 What's the best 100A Peak Pack?

I would not trust vruzend contacts. Its hard to say if all cells have same contact resistance. Better to have them spotwelded and your parallel wires connected to nickel. Wander if there are hall current sensors that could be soldered between cells to reduce distance between cells as this scenario i...

Re: 2020/21 What's the best 100A Peak Pack?

Your suggestion of the testing will result in 0 difference. Parallel cells balance each other out so you will see no measureable difference. Not enough time for the cells to equalize if you break apart the paralleled group of cells right away. But there is probably a better, even easier way. For so...

Dont know how smart he is but he cant do 1 grade math it seems: "Typically the batteries are linked together with 35mm cable in a good installation (often much smaller in a poor installation). 35mm copper cable has a resistance of around 0.0006 Ohms per metre so the 20cm length between each bat...

I would skip that article. 10A draw drop in a string between couple batteries with such thick cable is nonsense.

Re: 2020/21 What's the best 100A Peak Pack?

I have my modules covering most cell sizes, 18650, 21700(which can fit 20700) and 26650. Long time ago i was making kits for A123 AMP20 prismatics but my new design for cylindrical cells is so much more convenient. My line includes modules up to 8P and i have double ended ones which are used for 2S4...

I am having delays with restocking. Cause of this delay, people who will contact me before 2nd of January will get their 21% winter discount anyway as i could not manage supply earlier. Just write to agnius@1865o.com, describe what you will need and will get it sorted.

@klemkas are those packs the same size? 7s7p. Or are there more cells in the Vruzend? I always worried the NESE aren't as dense but these look great! Winter sale is tempting [emoji1] Cheers Tyler I can answer for him :) NESE is more dense than vruzend. Its even more valid when you cosider that vruz...

Re: N.E.S.E. the no solder module

@klemkas, thank you for the overview. Lids not closing is normal and that suppose to happen. Plastic is soft and cells bow it out. Thats why the lids have edges that catch on the bottom part. You need to squeeze the bottom part a bit to close the lid. Its a compression kit so the compression must be...

21700 and 26650 hardware and modules will be available at the end of December. 18650 ships as usual.
Shipping will incur delays due to Christmas and pandemic so bear that in mind when ordering.
Thank you for support

Re: N.E.S.E. the no solder module

UPDATE:
26650 hardware is coming mid December.
There will be another winter sale for a month as usual.
I will start selling V2 modules which are smaller.
I will have some V1 old stock at half price.
Now i need to hope all this pandemic nonsense does not affect me too much and i can deliver on time

The link in his signature works for me (albeit slowly). I think PLA can work, but PETG/ABS/PC are much preferred due to their higher temperature handling capabilities.
Thats weird. I moved my site to bluehost which is in US so americans would have faster service, gues its not that great

Re: Tool battery (Makita) mounts for ebikes

Mounting them is fine. How about charging 6 bricks? Even with dual charger you would need to attend 3 times to fully charge. Not that convenient.

Any thoughts on making the 21700 holders Vented? I would think that would help with heat shedding under high loads. Or, is this design available and I've just missed it?

Thanks!
