I have gotten multiple messages of people asking me to build batteries for them and trying to get a 10s2p battery for 140$ or a 12s3p battery for 220$ , stating they can get them at that price in China.
I cannot with good consciousness build a Battery with cheap components that will most likely fail.
Can some people please weigh in and state their minimums for safety.(cell current draw(mine is 20a under 4p), Bms’s used and minimum Nickel for series connections.
That’s a hard question to answer it depends on the battery? Those prices are based on cheap batteries that will not last, quality batteries are built with top of the line nickel,bms, and other components, please elaborate on your question a bit
Considering you can get 20 Samsung 25R cells or similar for around 50USD + shipping from ru.nkon.nl, $140 for a full pack doesn’t seem that unreasonable
Samsung 25R’s have proven to not be the best choice for Eskate batteries. Too saggy.
But even if they where good batteries, what about the cost of other materials involved, the cost of equipment and the cost of labor and warranty.
Hi, yeah I’v noticed that this community focuses on cheap over safe if you want to sell packs try and market to regular people not e-skatebuilders who think labor is worth nothing. Also they are most likely trying to low ball you just tell them to get it from china where you will spend way more then a couple $100 in shipping and customs.
It’s not about cost of cells guys if you actually want someone to do something you have to make it worth there while. Like if he lives in a expensive city why would he wast his time making you something for less then he can get working a minimum wage job.
Not to mention many now complain about the height of that battery and switch touching the ground problems, all of which are remedied by a custom battery
Figure ide chime in, I make battery packs for local pickup only, no shipping. This aspect alone is a big time/money consumer when factoring cost of selling a pack, dealing with shipping issues/damage, things not arriving working are all problems I never have to encounter. Also I don’t stock cells or BMS just assembly materials. On avg I charge about $100 for a 40 cell pack, you provide cells and BMS if you want and I provide everything else, you come to pickup the battery, you see that it works, take it home and use it. Can even have it ready in 24hrs if you want, assuming all materials on hand
