Thanks to Community Member WoodSlayR for sharing this deal.

About this Item:
  • 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.
  • 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.
  • 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.
  • Built-in Bluetooth allows you to monitor battery status in real time via your smartphone.

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 .

The only problem with the wiring was a tear that he did himself when he tore the lid off the battery. These batteries are glued shut and are not intended to be opened by the end user. To me it lloks like the wire was unintentionally glued to the lid when it was assembled and when he tore the lid off, it tore some of the wire insulation. If he didn't take it apart, the wire wouldn't have been torn. It would have been fine to the end of time if he didn't tear open the battery. I'd just take it as a lesson to not open something thats not intended to be opened. These batteries aren't customer serviceable. Other than that, it did have a high-quality JBD BMS which I definitely didn't expect at this price, and the cells themselves were laser welded so those are 2 high points.
Some people mentioned they didnt like how the wires were crossed inside the battery. there's zero problem with that. Thats what wire insulation is for. Consider this. Every single hot wire in an automotive environment that is close to any part of the frame, which is grounded is essentially the same as a hot wire and ground wire being close together but worse because the frame of a car isn't insulated. Hot wires running close to ground wires isnt a problem whatsoever. like none. Thinking about the tear in the wire, glues and adhesives are notorious for softening pvc and the insulation of the wire likely being pvc may have been compromised by the adehesives they used especially if it touches the wire before it dries. I'm just saying theres too many pros and good things about this battery to worry about things like a wire tear likely caused by him tearing it open or wires being routed closely together.
