I have been draining them down and bottom balance then up and getting things under control. What I am finding is a ongoing maintenance keeping the "deviants" in control. Been using all the tools and sharing a lot on other threads. I see light at the end of the tunnel. Reading and watching...

I haven't measure specific gravity in years. I top them off with distilled every couple of months. I have pick up a kit. Having the solar panel there to protect the tires will probably cause more issue with drying the batteries :fp2 I had thought about putting a fan in the cabin to help keep...

When a switch opens DC it want to arc longer than a AC would. Mechanically they usually switch faster and contact travel farther away. Look what inverters are doing. They switch DC high current all the time. I can be done just don't use a AC device for DC. There are also ways to do it what...

Any update on this? My only comment from having other brands is having removable cells is a good thing. Looking at the pictures it looks pretty nice.

I have had it hooked up for a few weeks now and have no complaints about the VSD and the pump spinning up, slowing down, heat, alarms or any pump related issues. HOWEVER, my salt water chlorinator doesn't like it at all. I get low salt & low flow alarms. I can see if you used this pump...

I ordered the contactor yesterday. Will enjoy a little torture testing :devilish: Mint Mobile getting into batteries ? :ROFLMAO: Mint Block Rack Battery https://mintenergy.us/products/mint-block-pro On Sale at...

I am testing the little 100Balance 1A Active Balancer. On sale <$15us on AMZ. Darn thing works. To small for my 15S 100aH but it is reducing the differential. I put a temp probe on it and not seeing much heat but only 1 amp.

I have the non Bluetooth one and it doesn't seem to do anything. I am going to return it on AMZ.

Once it get to low behind the others you won't be able to get it up (oh my) except charge that cell by it self.

After a certain amount of tinkering it is running the pool pump just fine.

I didn't install the software or should I say run it. I unzipped it and copied the older version into a different directory. I was going to use it after work that day. Then windows flagged it was a virus and quarantined it. I didn't have this issue on the older version that I ran a few...

I replaced my water heater a few years ago. I regret not getting a high efficiency heat pump design. Especially now that I could have run it on solar AND cool the room where my batteries are. We are in a miserable heat wave in Florida right now. I had to put a fan in that room to keep them...

I have tried everything. I contacted support@signaturesolar.com for the first time so lets see how that goes. Unable to get it balanced and over 55.31 Volts.

I had an issue of running just #4 on a 1KW load. It cut out randomly. My goal was to run it down for a little bit and then charge it up. It would cut out but didn't give any inforamtion in the HUB. The other issue is that the Hub was powered off the buss with only that battery on so it...

Nice work, I am not into 3D printing yet. Anything that I can purchase at a reasonable price and mount to a 19" rack? Would prefer something that didn't have open wires/connections to short out. Needs to run on 4 through 28vdc. I can upgrade Solar Assistant from by RP3 to Orange to make it...

I was aiming for 3.45 but the imbalance would make one cell go over 3.5 while the other was a 3.3 and change. My one success story was to run it down to 80% let it sit and then take it up to 55.2 and hold it. I'll get more creative next time around. Start work week back up. So the problem...

Example Screen shot of Reading the hub on the inverter port with a standard battery RS485 USB that came with the battery. I am reading battery #4 (APP ID). I bought a 3 port expander from AMZ so I can plut it in without unplugging my 3K-HV

I can tell you some issues I have with the EG4 LifePower4 (QT-YS00-16SV100A) Narada BMS >Only 6 balances going on at any time, maximum shunting current is ~300mA or 10-12 ohms. >It will stay balancing on a cell while another cell are at a much higher in voltage, software needs to jump around...

This don't look good. National Fire Protection Association (NFPA) https://www.nfpa.org/news-blogs-and-articles/blogs/2021/10/01/residential-energy-storage-system-regulations The residential chapter of NFPA 855 addresses the installation of residential ESS units between 1kwh and 20 kwh. After...

Nice breakdown of what goes on inside a breaker:

They are going after tool batteries, scooters, and consumer grade. Hopefully LPF will have different rules from the Evil Li-Ion. Sounds like someone needs to make and sell an inexpensive battery cabinet with a small HVAC for residential. They have them for commercial. Nice aluminum rack with...

It just hit me after I posted last message. A box Trailer wired in like a generator through a transfer switch. Only problem is DOT has Lithium rules... Ok, I like the shed idea.

Been looking at this battery box enclosure. Love the idea that it is already cutout for the JK Inverter BMS It looks similar to one Andy had on Off Grid Garage. Anybody try this one out?

I really wanted to understand how this BMS works in the QT-YS00-16SV100A rack battery. There are so many threads and people having issues. It shouldn't be that difficult to tweak the current firmware to get it to work better. The SOC 100% that was sitting at 54.0V all night. Then put on...

Just to throw another one in the ring. The beatings will continue until accuracy prevails! In fairness this was designed for a 48 volt system. Everything was divided down to the other voltages.

Now that is a serous DC breaker assembly. I found a couple for sale on surplus. Can't wait to hook them up with some bullet breakers Electrical Nominal Voltage -/+24-48V DC Voltage Range -/+19-60V DC Number of Buses 2 Bus Rating 850 Amps Max. Interrupt Device 1000 Amps Number of...
