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

If I wanted to add this as a secondary battery to a vehicle to power additional equipment, what else would I need besides a battery isolator, or would a dedicated charger be better, or is that already included?

Had the same question. Anybody building home solar batteries out of these?

A battery isolator is all you really need. Lifepo4 batteries need a slightly higher voltage of 14.6 to get to 100 percent but a regular car alternator that does 14.4 would still charge it to over 90% SOC. You wouldn't get full capacity but a battery this large, 90% of rated capacity, is still a ridiculous amount of energy. Charging it to an SOC of 90 wont hurt the battery and if anything, will extend its life. Not that you'd need to extend the life of it. These LiFepo4 batteries last forever. most are rated around 4000 to 8000 and even higher charge cycles. In other words, if you were to fully charge and discharge every single day without missing a day for 10 straight years, that would still only be 3650 charge cycles. Now imagining only doing 2 complete cycles per week or 100 cycles per year. It would last a very very long time. A LiFePo4 battery this large you can probably expect 15 years or longer of heavy use.

hope so. or, this is just shil companies from China disappearing after they build up sales and could have warranty service
I mean, there's plenty of domestic shill companies too.

Ever dealt with Comcast and had no other choice for internet? F*** Ajit Pai for that one.

The thing with most Chinese companies is they realistically only have a few degrees of separation between them and a competitor in terms of materials.

As long as the product is good, that's all that matters.

You'll be getting it much cheaper than if you bought it domestic, for what will probably be the same item.

And who needs a warranty when you can do a charge back.

You can and people do, but if you wanted to build the largest size possible you'd probably want to go with large capacity 48 volt server rack batteries. Nothing wrong with these, they just aren't as scalable to get to the largest of capacities that other configurations would allow. With that in mind, you could still build a very large substantial home solar battery pack with these. At this price it would also be very cost effective.

Meaning there are many ways I can see this being used, but not versed enough to know best use cases.

i just watched a review that showed it outperforming its rating by about 5%. the main problem for him was the build quality.

Pardon the ignorance. Are these batteries the same type that are used in EVs for backup in case the main battery fails? TIA

The build quality wasn't bad. There was that torn insulation on the cable but its likely he tore it himself while trying to tear open the battery. These batteries aren't easy to open nor are they even meant to be opened. These batteries are so small nowadays that all the internals are cramped close together so I could easily see someone nicking a cable while trying to cut open the battery. They are glued shut and tearing them open isn't an easy task. Components were high quality especially noting the JDS BMS and the laser welding to wire the internal cells was a nice touch.

best use cases are going to be different from person to person.

That's capitalism for you.

There was a time when nobody knew who Anker was.
I thank the guinea pigs that have money to burn to test these out.
