Hi all. Does anyone have experience with the BMSs from Daly? I'm looking to get a 16s BMS for a DIY li ion battery pack. I have a large box full of li ion 18650 cells and want to make an emergency battery system for home use.
That power outage in Spain motivated me to finish this project.

They tend to be not great from my reading.
You're likely better off going with JBD or ANT BMS. Both are on aliexpress.

I have the Overkill Solar JDB BMS and it's awesome. I've been using it every day for the 4S pack I built for my van. The Overkill Solar app is really nice and I believe it works with any JDB BMS even if you didn't buy it from them.

I definitely prefer the JBD app but it's nice that there are options!

Hmm ANT does have better documentation and differentiates between peak current and continuous current. They look more genuine.

Yeah, they have models with active balancing too for faster balancing.

All these BMS seem more designed for high amperage solar system storage, generally using LFP batteries. I'm sure it's possible, but it seems like overkill.
Also Li-ion is not something I would keep in the house, especially a home-built pack. There's a high likelihood of fire. I built myself a battery pack with the same sort of cells, and a few weeks in I happened to walk into the garage when the pack started spewing flames out the side. They can be touchy and definitely need temperature sensors/current control.

Good point and this is exactly what I'm trying to make. I want to start with the battery for emergency power and want to add a home made MPPT solar charger to it.
My battery design involves having a thermal fuse of 65C sandwiched in between parallel cells. I will also periodically check the batteries with a thermal camera to see if any are misbehaving.
