【EV Grade A Cells & True Capacity】 TechCella 12V 320Ah LiFePO4 battery is built with automotive-grade A+ cells, featuring excellent voltage balance, ultra-low self-discharge, and stable performance. Delivers more than 320Ah actual capacity — more usable power than rated. Compact size (13.58×7.48×9.64 in) and 58.43 lbs weight make it perfect for RVs, off-grid systems, and trolling motors
【【200A BMS & High Power Output】 Equipped with a robust 200A smart BMS, this battery supports up to 300A peak discharge for 10s, ideal for high-power appliances and motor startups. It auto-recovers from overload protection within 30 seconds, ensuring continuous operation without power drop. With -20°C/-4°F to 60°C/140°F discharge range and charging cut-off below 0°C/32°F, it's built to perform safely in extreme conditions
【Smart Bluetooth Monitoring & Easy Setup】 Built-in Bluetooth allows you to monitor battery status in real time via your smartphone — no need to remove the battery or install extra monitors. Easy to set up with no complex wiring
【Upgraded Internal Protection & Stability】 Designed with enhanced safety in mind, the battery features an insulated sleeve on the negative wire to prevent abrasion and protect internal circuits. Extended adhesive curing time ensures a more stable and secure internal structure, reducing risk of damage over time and improving long-term durability
【Fast Charging & Tips】 Supports 20A–160A charging current and fast charging with a 14.6V 50A LiFePO4 charger, fully recharging in just 6.4 hours. For deeply discharged batteries, we recommend using a charger with 0V activation to restore power safely. To protect battery life, start charging when capacity reaches 10–20% to avoid BMS low-voltage shutdown

12v LiFePo4 batteries are getting incredibly smaller and more power-dense by the year. Its size of 13.58"×7.48"×9.64" is incredibly small. It's about the size of the average 100ah battery of yesteryear, but 3 times as heavy while having over 3 times the power storage. I own 2 XZNY branded 280ah batteries that are also incredibly small, and very heavy.. they are about the same exact size as these but they dont have Bluetooth. Having bluetooth is such a nice feature to keep exact tabs of battery state of charge. The only review I've seen on you tube verifies this battery has true rated capacity but the company is pretty new so there isn't many reviews on youtube. I've seen some reviews for their 100ah batts and they all check out good so whatever's thats worth. 320 shipped for this much power with bluetooth in a very small package is a phenomenal deal.

For further reference for size comparision. Theres a MFUZOP 12V 100Ah battery here on slickdeals thats very close to the same size as this 320ah battery. These 2 batteries are very close to the same size but this has bluetooth and over 3 times the capacity which is pretty remarkable. the exact measurements of each battery is 13.6×7.5×9.6 vs 13x6.7x8.6

Actually not true. In the USB battery market thats true but not the 12v LiFepo4 battery market. I think brands are starting to understand that consumers are getting more and more tech savvy and its harder and harder to slip by a sub par product onto the market and expect it to sell well.. A lot of it has to do with youtube and the endless number of people that review these types of batteries. When it comes to 12v LiFepo4 batteries, there are actually far more that test true to rated than test less than rated capacity and the less than rated ones are quickly exposed by influencers and the endless number of people that test these batteries. If you were to enter the highly saturated battery market today and try to sell a falsely advertised sub capacity battery, you wouldn't last long. Customers are far more tech savvy and connected through the internet to learn and share with each other more so than we've ever been in the past. As a whole, the consumers become smarter and more tech savvy and we become harder and harder to dupe by companies that try to lie to us. Companies are starting to learn fast that the modern consumer isn't the same old clueless ignorant consumer of the past and that a good thing. Consumers Win.

If this were universally true, it wouldn't take long for people to catch on.

This happens far more often with some of the ridiculous battery banks that get posted here, where the sizes just don't add up to cells that exist in reality.

Its far more true in the usb power bank world but not the 12v LiFePo4 battery world. Modern day consumers are getting too smart and tech savvy for them to sell sub par/capacity junk to. With tools like youtube and the endless number on influencers/battery testers, it becomes harder and harder for these manufacturers to put crap out onto the market and expect it to do well.

New companies pop up all the time.

That's capitalism for you.

There was a time when nobody knew who Anker was.

While there's some truth to that, even new legit companies have to begin at some point in time. No company cant start up with 10 years of existence. One thing thats a good sign is they have a very extensive line of products and the few reviews that can be found are good. As the company gets older, more reviews will pop up.

Thanks for that video! After seeing the wiring inside, I feel like it's not safe enough to use .
