Vruzend Kits...

There are two advantages to these things (all such kits): Can do wiring'soldering without cells in place ...and, FWIW, no outlay for spot welder machine etc. The other fiirm, Nishi is just not worth anyone's time...virually not existant on-line. Rest is hustle. Besides, the firm response to emails a...

Metals Mix

I figure mixing metals is okay, as long as less-conductive leads to greater-conductive, as in Nickle to nickle coated copper. Right? Please excuse basic level question, but am learning, bit by byte here.

Good Players and Lame Makers

FWIW, I know crappola about EV...built two 10s pacs...both Vruzend thingies. I will say in my perusing to learn, I have found tomjaz and spinningmagnets to be invaluble teachers; genius, and there are likely others which I have yet to endounter, so do not feel left out. Thanks. The other side of the...

Re: RANS e-Bike Possible?

The mid system would be the best choice for weigh dispersal without a doubt. My recommendation would be to buy something built from the ground up as an ebike. The long story is, if you care to read, I put a rear hub system (Heinzmann) on two Fusion STs for my spouse and myself. Most comfortable tou...

Re: RANS e-Bike Possible?

I'm not sure if you have ridden the bike, but generally this bike geometry is quite inefficient compared to bikes where the bottom bracket is at the same or almost the same height as the seat, or compared to a normal diamond frame mountain or road bike. So you will REALLY be needing the electric as...

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

Not smarter, just lucky or easier satisfied. I will say, I like the through-bolts, and was irked a bit they came late and not available. But, am also cheap and pragmatic, to a point. I have two kit-packs I bought and built from Vrz, and wrapped them with that clear plastic stuff usually seeen on lar...

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

Was ambiguous...did not mean "prevent" just that I feel bolts are not needed. If wrap...I used plastic from spool...is tight, the pack holds no matter what, for me. I do streets only.

But, your point is well-taken, any outfit adding improvements should meke them available.

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

I don't know if the barrel bolts are a biggie. I have the early kit and the later kit, before the long bolt additions. Seems the wrap holds things in place, making the bolts unnecessary, however, the lack of the item for sale is a good and well-taken point. My complaints are similar: Lack of compone...

I am not so sure I "get it" but I bought and assembled the second (black/orange) kit from Mikah to add to the first to extend range etc. I think, the kit is excellent. copper...etc. The first kit I replaced the buss bars with strips of nickel, as I found out they were coated and would not take solde...

Tinfoil or Any Metal for Parallel BussBar?

Does it make any difference what metal is used in parallel connections, considering small voltage?

For example, the series buses being all nickel...can use small copper wire, SS or even tinfoil for the parallel connections on a 36v pack 10s3p???

@ eee... I have acquired items from Japan, Thailand, UK, etc. All were swift transits, save UK and China.

Thanks...have similar visions...will likely do as I said, even if it takes long due to slow shipping, and better order before tariffs are imposed.

Gee, all that? Seriously, looked over lots of reviews, never read about dents and loose cells...every time I turn around, it is something else, maybe I should get the other ones...no tops etc and just spot-weld...

BTW "flippy," don't pooh-pooh the cellholder/placeholder stuff...has some shortcomings, but with some tweaks, makes building a b-pack simple and, generally speaking, very minimal soldiering.

Am new at this and study up first...but search is "iffy." Only using the plastic and inserts of the kit, as I have them and simple. Learning as we go.

Thanks...Some battery place noted here, these were new, like the green Panisonic NCR PF 2900ah in pics. I think price was close...maybe around 3-$coots shipped.
