Offering Battery Assembly

[gizzardelectric]

I'm planning to build a custom battery company, having built and rebuilt packs for myself in the past (@gizzardelectric on instagram).

I'm located in Seattle, WA--if you're interested in having a pack built the money you spend will go to building a website for future orders.

If you have input on what your ideal pack-ordering website would look like, please leave a comment! My current idea is something like the old cheapbatterypacks.com for those of us who remember the golden era of RC.

I am currently trying to get quotes to have a battery built so you're welcome to provide me one as well . I am looking at a 72v 60 AH pack with max discharge anywhere in the 150-200a range (depending on the cells you recommend)

I am currently trying to get quotes to have a battery built so you're welcome to provide me one as well . I am looking at a 72v 60 AH pack with max discharge anywhere in the 150-200a range (depending on the cells you recommend)

I like the Panasonic cells (Panasonic NCR18650GA 3450mAh 10A Battery) because they don't catch fire. ((start video at 34:44) Grin’s perspective of Ebike fires)

For a rough estimate w/o shipping I'll just 2x the cost of the cells--72v is 20s and total AH, (60/pack)/(~3.4/cell)~=17.6, round up to 18p for a total of 360 cells. Incidentally at 10A output each your max discharge would be ~180a, comfortably within your range.

They're currently $3.80 at 360 cells (I swear I spec'd based on your constraints it just happens to have a bulk price right at your number), so the cells are looking like $1,368 before shipping. That said when I actually add to cart I'm shown a $1,242 price, there must be a sale I don't know about.

So my bid. $1,242 *2 = $2484, you'll pay that price whenever you'd like me to order the cells, and I'll handle secondary materials, labor, and shipping from there. (note shipping times and costs will be based on to/from Seattle where I am)

Anyone else reading this thread can do similar math for an implicit quote from me, and hopefully with enough interest I'll be able to observe more accurate [secondary materials, labor, shipping] costs and expose a website that allows ordering with lower cost!

Incidentally, did you ever have the pleasure of ordering from cheapbatterypacks.com when it was operating? You'd be able to select cell type, #series, #parallel, connectors, and receive a spec sheet with the resulting pack's characteristics and a price with shipping options. It was really sweet.

Curious if you would be able to meet for a coffee I'm in Redmond and have picked up the art of battery building within the past year. And there are a few things Im still learning and I'm one of those people that need to be Able to see it done in order to learn I can't be told how to do it .if that makes any sense? I've probably to this day built around thirty battery's now. And fixed a good share also. Only with 18650s so far I ended up getting a couple thousand lgs and Panasonic's and a couple hundred baks. But I just stumbled upon a couple hundred Samsung 50e cells so I'm going to build a few packs with them. Excited as they have more mah then 18650 which means I can build packs with higher ah in the same amount of space. I've been injoying the polly d9 cases as of lately for my builds . I also just purchased a used onyx rcr which came with no battery or hub motor. Which I lucked out and happened to have a 3000 watt hub motor which came off of a onyx rcr that I have been running on my radwagon. Lmao don't judge haha it was a a fun bike and fast but now im excited to put it to it's full power onbthe onyx but I still lack the battery i have a few 72v 120 amp BMS but I'm sure I need much bigger and I want one with Bluetooth also should I build a pack with the Samsung 50e cells as to try and reach as close to 55 ah as possible? And if so could u point me in the direction of which BMS I'd want to use thanks a bunch
