Are this Genuine EVE 304AH Batteries?

I used Orion BMSs since 2015 until last month, when I converted from a DIY pack to some Pytes rack mount batteries. I had Grade B cells in a 3P16S configuration and they needed more balancing current than the Orion could provide so I disabled the balancing on the Orion and used a 1 Amp JK active balancer. The Orion JR2 communicated easily with my SolArk and the SOC measurements were very accurate. It used a Hall sensor for current measurements.

Orion. If you've been looking for a BMS that will prolong the joy of the DIY build process into tens or hundreds of hours, and repeatedly demand another couple hundred bucks from you for necessary accessory parts, then I really recommend it. It's the best.

Rather than keep spamming new threads out as thoughts come up I'm starting a build thread now to share as I go. 16x EVE 304 from Ezeal Orion JR2 BMS Planning work in progress (polarity not detailed yet):

It's the Orion JR2 and I got mine used from another member on here in the buy sell forum, but Evolve Electronics is the retail distributor afaik. Careful, the Evolve listing will offer to sell you a contactor too as a common accessory, but theirs is a 12v coil and it's polar and both of those factors may or may not be correct.

The Orion can be powered off the lithium pack itself or by an auxillary 12v battery. I do use an aux battery so my contactors are 12v coil, but a lot of solar battery builders do power their BMS off the pack itself.

Also just to be clear, I would advise against the Orion unless you are glutton for punishment and do want to build a battery on hard mode. It's a lot to learn.

No problem. For 48v packs, JK seems to be the most popular among enthusiasts. But I don't know the specific models.
