Selling a Victron Energy Quattro-II 48/5000/70-50/50 230V. It is important to note that this is a 230V model and can be paired with Victron's Autotransformer for split-phase 120/120V. This is great if you want to use high-power electronics (well pumps, AC Units, driers, welding...etc) while also...

I have a 4-battery packs with cells in 16S (EVE 280K) and am using the WatchMon-CORE kit with a CellMate-K9 for each pack. I have had issues with a few cells not staying balanced in different packs. What is confusing to me is the voltages batrium is reporting...if my pack voltage is 55.20 that...

I bought the Multiplus and Autotransformer almost 2 years ago. This setup allows split-phase 240V without needing to run two separate inverters. All your loads will be balanced in this case. This is a 230V (it's set to 240V) Multiplus and the Victron Autotransformer which splits the 240VAC into...

I have a Kilovac 48V Contactor/Relay LEV200A6NAF that my BMS controls to allow or cut power from my battery system. It takes a constant ~48V to keep the connection (closed circuit), and when the leads receive no power from the BMS the circuit opens and it cuts power. I recently set it up and...

Does anyone know what the current state of getting data off of the Batraium BMS (WatchmonCORE) is? I tried this repo and got it up and running in Docker, but it didn't receive any data from my Watchmon. I've also followed some other threads pulling Batrium data into Influx and Grafana but I...

I have been scouring their documentation and google trying to find how their Solid State Relay's are powered. The only details I see is that they have a + and - on the schematic. But it is unclear where the INPUT source is for that. I have tried providing power to the expansion boards two INPUTS...

I'm aware you are not supposed to run AC and DC wires in the same conduit because it can induce a DC voltage onto the AC side. My question is, does that only apply to longer spans? Can AC and DC wires be next to each other for short distance of say 3-6ft? There is area of my house where both...

Hey Folks - I'm looking for a charger that i can use to charge single 1000mAh cell to as large as a 280Ah cell. My source would be 120VAC on a 15A breaker. I need to be able to control voltage/current and would love to set it to stop when certain thresholds are met. I've eyed the ZKETECH...

Over the next few weeks I'll be setting up a new battery system for my off-grid home. I bought 64 EVE Lifepo cells (280Ah@3.2V). I'll be setting them up in 4 groups of 16S (16S4P?). I feel a bit unclear on how to charge the batteries up to 90% SOC. I'm assuming that's determined by the...

Knowing what I know about Lithium I started looking for a tool that would let me limit the SOC of my macbook battery. The newer MacOS's will even do this to an extent by learning when you use and charge your battery, but didn't give me as much control as I wanted. I found this application while...

I was just about to buy Midnite Solar 20A breakers for a PV combiner box, but I realized they are only rated at 150VDC. I have sets of 4 panels in series putting me at around 200VDC. I can't seem to find breakers rated at that voltage, but I cannot be the only one series my panels at that...

I need to buy a roll of wire that I'll be using for my BMS & balance leads. I think solid core makes sense but I'm open to suggestions. Do folks here have any go-to high-quality wire that they like to use in the 18-20AWG range?

My Setup: I have 64 LiFeP04 cells coming my way. I'm very confused on which Batrium products I would need to support my setup. I think I'm confused because in their BMS kits, nowhere does it say what products I would need for a 16S4P. I do not have any existing Batrium products so I'm starting...

Hey Folks - I have 64 LiFePO4 Eve cells coming my way, but I won't be able to install them for another 3-4months. I need some advice on how I should balance and store them. Does it make sense to put groups of them in parallel to let them balance? Should I connect a BMS now and let it keep them...

I'm setting up a LiFePO4 battery system (2P8S X 3) and like many post's here I'm trying to find which BMS I should go for. I use HomeAssistant to monitor many off my off-grid systems including my current solar/battery setup. Since I'm switching to Lifepo I'd like whichever BMS I choose to easily...

Quick background: I live off-grid and am ready to replace my 12-year old Flooded Lead Acid batteries that our home/systems run on. I'm looking at buying 35 of these Samsung EV modules from BatteryHookup which would give me 72KwH of storage. They are offering me a bulk discount and free shipping...
