Features

Details from the TechCella Amazon listing:

• 【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
• 【4S4P & Long-Term Reliability】TechCella 12V 320Ah lithium battery supports 4S4P configuration, reaching 51.2V 1280Ah, delivering an upgraded capacity of 65.536KWh. With over 6000+ deep cycles and a 10-year lifespan, it's perfect for DIY battery systems and ideal for home energy storage, RVs, and other off-grid applications
