Idiot's guide to a self build battery

Of course Fogstar now have the BMS I bought but significantly cheaper. It's on sale at £79 and without the import tax. And it's the 200A version.

and comes with an interesting/honest caveat:

Note: JK provide no instructions with their BMS apart from those included in the downloadable PDF. We strongly recommend that you have a good working knowledge of LiFePO4 systems and BMS electrical equipment before purchasing this product.

And I hadn't noticed it isn't the real fogstar site either.

Not sure who this is in response to, as i cant find the original post to link that fogstar page.
....
My battery boxes i ordered, along with the new jk bms and 4.5" screen, was cancelled by the seller due to an issue with the box quality apparently.
They still posted the bms, and the screen x3, and refunded the rest, before they told me.
I have sice decided to go with something vertical or horizontal capability, so have 3x gobelpower cases on the way. They have the old JK bms in them from what i gather, despite showing a pic of the new ones on the site.

Depending upon which bms fits the gobelpower case, i will then have 3x bms spare.
I wouod prefer to fit the newer one but the older jk bms has the neey 10 amp thrown in for free, as a deal done by gobelpower for me.
So it literally is a case of which one fits, as to which i have spare.

Andy, from Andys Garage, has a 1.5second segment on a video, trying to fit the new jk into a GP case that has a screen. Mine wont. He said it didnt fit... i dont know for sure if i can make it fit in the space the screen takes up, until it turns up.

So, long winded, but if anyone is needing a bms, i will have either, 3 older jks with 10amp neey available at cost, or 3 newer ones, when the shipment arrives.

If that helps anyone, then let me know.
I will definately be parting with one or the other.

Yeah, crazy they can't make a manual, or apparently even get tech specs right on their website. Be aware JK managed to wire their pinouts back to front on the inverter BMS connection board, their own website showing the specs is wrong which someone else worked out what it should be:

wow!
Call me old fashioned but I like accurate pin outs and manuals the same. Silly I know.

That's excellent, marine tracker must be running delayed.

Should be about next week , then the battery will be arrived
Shenzhen rains heavily today

I'd better get my finger out and clear some space for those batteries arriving

I think something is mixed up on comms here. Ship is docked in Rotterdam at the moment.

i expect Felixstowe to be next dock in a day or so depending on alongside time in Rotterdam. Nearly there!

Yeah! JK have some of the best BMS's but terrible documentation.

Exciting! Looks like Monday at Felixstowe, I hope customs don't sit on it for the next few weeks like they did mine

Is it worth editing all the links so that people can't accidentally click on them? I'm doing my posts now.
