@etchedpixels - why would an electrical engineer be using a Sparky for connections to a battery operating at 52v nominal?
Why get a battery pre-built ?
1. Because you need the tools and to know how to do it safely. Things like gloves, no jewellery etc, correct torquing and the like.
2. Because most electrical engineers are paid more than a sparky so you can earn money to pay a sparky to do the job better and have change and time to do something else more fun.
3. You have a warranty and someone to blame if it fails
4. It's got CE/UKC and other approvals which avoids awkward questions later (eg if you want sell a house and leave it wired in).
There was a time that building your own battery was actually worth the effort. The prices have dropped and dropped and that window is mostly gone. Sure if you enjoy it then why not but otherwise it's a lot of hassle.
@etchedpixels Absolutely, I built mine as I assumed it was as simple as Fogstar made it look like. But even then, instructions were not fully up to date and it was not a pleasant experience. Fogstar was there to provide the info but when it got tough, they slowed down and I ended up liaising directly with the manufacturers..
And office banter is.. for the office
