XR04 + ENVISION 305 DIY 48v Build Photo Diary

[Herculezz]

Hello yall, I am just so happy with these boxes and the service their company provides I just had to share my build and thoughts, these are very well built and have everything you need for a complete professional looking and high quality build for an absolutely unbeatable price, I got the boxes for 260 each all in, shipping and tax, and the BMS is JBD I got for 90 on sale, for a total of 350 for the complete box, which is insane, add in the 1400 for the 305ah cells and I'm total in 1750 for a 48v 305ah battery in a box, pretty great price, check out my images.

Awesome. Where’d you order the box from?

That does look good like a good package!

Yellow busbars look a bit shonky though.

Hmmm I see they offer XR-01 in an 8S

For the display cutout are you locked into that JBD display, or you think a JK display could work.

Totally different from what I got, mine are Seplos BMS with very different balance connection method.
Also the black sponge is suppose to go under the holding bar, not on top of the balance PCB. It protects the cells from the holding bar rubbing on them.

How long did it take to get there? I ordered my X05(Vertical version) in late January.

Not sure I would buy these cells again, Great deal but shotty welding on the terminals, I had another one come off with very little force and you can see it was only half welded, and I haveba third that you can see is the same only half welded being held on barely by the other half but I am making it work by being careful with that one.

Where did you source the cells from?

It appears that Xinrong has recently released a new battery case called 'XR-08' equipped with a JK BMS.
Although the lack of protective devices like circuit breakers or fuses is a concern, the price is attractive.
