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.

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

I'm offering $4,700 which comes out to the same $/ah
on top of that, your still getting 640ah less power.

Stuff like the EASYLONGER on Amazon (B0BW8D3Z2B) is Li-ion... I really want to try LiFePO4 which has been very difficult to find in the past month of on and off searching.
Edit: It seems like that EASYLONGER thing on Amazon is actually LiFePO4 so I think my search is over. ES960 for home (B0BW8D3Z2B) and ES400 Air (B0C4PKWD36) for airplanes
Double edit: ONLY the ES960 is LiFePO4, the rest are Li-ion. So I am still looking for a 150Wh limited one for planes I guess...

Will it be used primarily for just emergency power when the grid goes down temporarily, or do you want a sustained solar powered setup to live off grid completely? The answer to "how much is needed" or "enough" will differ wildly from person to person.
