I made my share of mistakes building my battery packs then I come to this site and read and find my mistakes could have been avoided if I would have read here first. So with that said, what are you all using for a multi-function battery Monitor Meter. I have a small Nissan Leaf pack, a 14S80P made with 18650's and now I just attached 3.3kw of 26650's and I would like to know what each is doing without using my current clamp all day. I'm looking at the two pictured. I'm leaning toward the shunt over the hall sensor. What is everybody using?
Thanks

I have the second style on a little portable pack and it sucks. I have a victron BMV on my fixed setup and it is awesome. I have the model without bluetooth and added the dongle so I can use it in the victron smart network. Victron releases updates for most of their products regularly and they update OTA via BT.

Thanks gpn, sorry you wasted your money on the sucky one. And that's why I come here and ask, no need for us both to buy junk. I greatly appreciate your reply.

That is some chinese brand he uses. It looks decent. I use a Victron BMV-702 with the bluetooth adapter. It is more energy efficient to go with the 712 that has the bluetooth built into the unit. Whatever they are using for the external bluetooth adapter has some wild range to it. I can connect to it from 100' away through 5+ interior walls.

When I finally build out my medium (2.25kwh) suitcase portable I will likely just use a victron smart shunt. The whole contraption is on the shunt including the bluetooth part. But it doesn't have a display.
