No, you didn’t…only today when you bumped it, and cross posted the exact same rant about battery pack prices from another thread.
Ok, hence the “I think”, not, “I did”. I don’t even know what that’s supposed to mean, bumped it, regardless, it’s not like I said anything off topic for the thread so again, don’t get where the hostility is coming from. If you guys wanna be pissed I have an opinion that I’ve heard expressed by many others and chose to comment, well I’m sorry you feel that way. I’m done with this pety childish argument BS though so I’m gonna turn my attention elsewhere.
Like said, your paying for their knowledge, service, warranty, and simply convenience. It’ll cost as much with the tools to build one, so if your only building one board, the costs would be about the same and then you don’t have to worry about messing it up.
Now I agree, that I would never buy battery pack at these prices, but that’s cause I have the skills and knowledge to do it myself. If I didn’t have the intuition I have, I wouldn’t try, because it is risky. You need to do it right.
Now about the hostility, I don’t quite get that… I think maybe this:
Might be misleading. You leave out the bms cost, which can be $80-100. I believe it should take about 3 hours to do a good battery pack. At $20 an hour, that’s $60 in labor. Power switch, copper, and other parts could be another $20-30. 36 cells at $3.50 a cell is $136. So $325 at cost for a complete 36 cell pack is reasonable. So selling for $500 at that point gives a profit margin for the business to deal with equipment costs and validating your warranty if something happens, and for growth.
Not trying to argue with you, just trying to shed some light on the numbers.

Thank you for not jumping down my throat. Normally the things listed would be included, but the battery packs I’m referring to don’t come with a BMS, or an On/Off Switch with the anti - spark and all that stuff, I’m talking about battery packs that are literally just the cells put together, a xt-60/90 connector, and the JST Phase wire connector. That’s it.
If the cost was what you quoted at $325 then yes that is quite reasonable. The cost of the $500 one I was referring to couldn’t be more than $150, that’s not reasonable IMHO…
Think about apples phone markup, how much do you honestly think it costs them to make the same phone they sell for $1,000+, now referring to a pack with just cells and spotwelded a 500 markup would be crazy, but for example a 10s3p spotwelded only pack at 175 + shipping would be fair

100% mark up is standard buissness now a days
I agree a 10s3p for that cost would be fair, I would even say they could charge a bit more, but at $500 that’s is way more than a 100% markup. That’s what I’ve basically been trying to say. As @willpark16 put it, that’s crazy! My sentiments exactly!
