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?

Thanks for all the recommendations. That's a nice inverter, but very expensive. I will keep it in mind if I need heavy loads. Overkill Solar looks great. Will check into their BMS. I already looked at the AIMS power converter, It's on my shortlist.

Good idea. I have serval of them. Not's need a specialized LifePo4 charger? I just saw a video where they used an old laptop charger and plugged it into the Solar Charge controller (just replaced the plug} That was smart.

Thanks! Any thoughts on chargers?

DALY BMS. Just have to find the right one. I'm considering a Daly. There are 80 batteries in the pack. The batteries are 20P. 4 packs. So only need 4 leads.

I plan to add a solar charge controller and an AC Charger. Primarily this project will be used as a portable power bank and will mostly be charged with AC power. I'm considering a Victron, I like the Bluetooth feature and know they have a good reputation. There are many models and Amperages...

Just purchased my first LifePo4. For my first DYI project. I will update everyone on these batteries when I get them. Looks like they are hinting that they may be from the same supplier that Battle born uses...

Welding my own will be for my second project. Want to start with something easier. Just getting started. Going for a portable box. A power all would be nice, then would definitely weld.

Positronium Thanks for the warning,

Your right. But faster than many promises on Alibaba. If I want them in two weeks I can go with this. https://www.amazon.com/dp/B08RWSZNNG/?coliid=I2Y88X8DW6RD0T&colid=30HS5UT99WI65&psc=1&ref_=lv_ov_lig_dp_it

What shipping time have you all been getting from China?

4pcs/lot LiitoKala 3.2V 200Ah lifepo4 Battery 12V 200ah $458. $0.18 per Wh Definitely a better price for a US seller. No reviews though. https://www.amazon.com/dp/B08SLLW9FL/?coliid=I1MT3RD9UPNAFW&colid=30HS5UT99WI65&psc=1&ref_=lv_ov_lig_dp_it

https://www.amazon.com/dp/B08SLLW9FL/?coliid=I1MT3RD9UPNAFW&colid=30HS5UT99WI65&psc=1&ref_=lv_ov_lig_dp_it This seems too good to be true for a US supplier.

I appreciate everyone's feedback. I have decided to build my own. Point taken I'm going with LiFeP04. I have selected a Dewalt tough system for my project box. https://www.homedepot.com/p/DEWALT-TOUGHSYSTEM-22-in-Medium-Tool-Box-DWST08203H/203696527 Considering the following batteries. They...

I was considering building a 3.5 kWh solar generator in a Craftsman toolbox. Looks like I can get a similar pre-built one here. Any thoughts? Buy or build...
