Make sure you research the risks of the Ternary lithium battery. It's currently on sale for $479 on Amazon with this code. 40AJWEPQ This a sweet deal for a 11000Wh solar generator. My concern is safety. Does anyone here have experience with Ternary lithium batteries...

I have 24 cells. Looking for a configuration for that, and recommendations? Looking for custom bus bars. Mssoomm Tin Copper Buss Bar is an option. Looking for a cheaper one.

OK so 3P 6S Then use one BMS? 24v 8s BMS 100a LifePo4 with 24″ 8ga Wires A BMS for each cell would cost more than the batteries.

I purchased 24 Pack 3.2v 25ah Lifepo4 Topband Prismatic and want to build a 2000W battery box. See attached picture. the 3P bus bars are not installed. What Gauge should I use? I'm using the following bus bars. I'm planning an 8S 3P setup. 24V. Added a DC Stepdown transformer to 12V for 12V...

48 430W QCells G6 for $212 plus shpg. Do you mean 48 panels? can't be. Do you have a link?

I hear you. The used ones would not go on my house. I just need power in my shed for charging the mower and a few lights, for my first solar project. They have new panels too. https://store.santansolar.com/product/qcell-310w-mono-solar-panel-duo-g5-blk/ 300W for $150 each. Could go with two of...

hi, I checked out the panel you are looking at and talked to Kevin Banks at SunTan solar. He was very helpful. answered all of my questions and provided me with a quote. he stated the used panel you are looking at is at least 80% as good as new. Getting a 250W panel for $63 definitely works for...

Joe, Very nice. I will let you know. Got to measure my batteries. How do you keep heat from building up in the box?

Thanks for the feedback. Where do you recommend specifically sourcing the LFP cells?

https://batteryhookup.com/products/bmz-samsung-48v-13s7p-704wh-module-with-bms I know it's not LiFePO4 but Lithium-Ion. I'm using this for an infrequently used emergency battery box. Is this a suitable inexpensive solution?

I'm building a battery box. That can be charged with house current or solar. Have design ideas from watching videos from Will Prose, David Proz and many others. Planning on using 3.2v 25ah Lifepo4 Topband Navitas Prismatic when they get back in stock. Dimensions: 7 1/8 x 2 3/4 x 1 ⅛ 66g...

I like the idea of crushed pipe. Might go with solid copper though. Bus bars are neater. The cables will give me more flexibility though. I might go with battery cables with copper connectors. I could make my own eailsy. I'm definitely waiting until I have the batteries in hand. Found these...

Wow, thanks! There is a lot of great information here. They should rename Aliexpress to Aliponeyexpress. :) My first project will be sourced locally. the next one can be from Aliexpress. Not ready to wait 2 months for parts.

Please let up know how this went. I might try something like this.

I'm considering these cells when they come back in stock. how are you tying them together? Battery bars? What's your source?
