Thatâs only if you buy 1000 or more, donât have any employees, have a free building to store your stuff in, have free electricity and internet, donât ship stuff, donât pay taxes, never lost a shipment or had a disgruntled customer, never made a mistake, donât need any other supplies to make the battery, didnât spend any money practicing on battery-making-skills, you work for free yourself, and you get free shipping supplies.
So no, it absolutely did NOT cost $30 to make. Probably about $250
Didnt mean it in a bad way, I was just surprised at the cost compare to samsung or panasonic cells that"s all.
Yeah of course there are a lot of thing to consider building it
They are selling this pack for 178 dollars.
Isnât it more simple to find a BMS compatible with my battery pack since it has such a low discharge rate?
Or does it have to be the specific discharge rate and canât be superior?
Many will work, but this is an important safety device and you donât want to use cheap stuff. I just provided a link of one which will probably work. Many others will work.
Bestech is a manufacturer, buy them from their Litech distributer on the link above. They have more 10S models, just ensure âbalance current for single cellâ rating is not missing.
Haha, you mean like sweep it under the rug? Lol!
Others may have different opinions on this, but if a crappy weld led to one balance wire coming loose, consider that all those welds were made the same day on the same machine by the same person⌠so you will likely find other wires on the verge of coming loose.
In an end-of-days scenario, I would re-work the pack completely⌠i.e. Strip it down to bare cells and start over. This would be more work than just making a new battery, since you have to dissasemble it before you start. Realistically, Iâd sell it for scrap value, get new cells and build Or buy a new battery.
The batteries we use in these skates are very powerful. They demand respect and caution at all times and relaxing your guard can lead to catastrophe very quickly. My .02.
I had my first issue with a flipsky 4.20 plus - setup using the wizardâŚbeing a dumb-ass I thought I would try FOC it seemed to be fine on the bench , did a very quick test moving itself - one side seemed to have less power and while I was investigating ⌠one side locked up and no longer turns on.
