TechCella is upgrading to our new brand name — Techex. While our name is changing, our commitment to providing high-quality batteries and reliable after-sales service remains exactly the same.
- 【Built-in Heating Function for Cold Weather】 The intelligent heating system activates automatically when the temperature drops to 0°C (32°F) or below, preventing low-temperature charging damage. Heating stops at >15°C (59°F) or during discharge, and charging resumes automatically at 3°C (37°F) or above. Heated by your charger (≥7A recommended), it ensures safe and efficient charging even in freezing weather
- 【EV Grade A Cells & True 320Ah Capacity】 Built with EV-grade A+ LiFePO4 cells for superior voltage consistency, ultra-low self-discharge, and stable performance. Each battery delivers over 320Ah of actual capacity, providing more usable power than rated. Compact and lightweight (13.58×7.48×9.64 in, 58.43 lbs), perfect for RVs, off-grid systems, solar setups
- 【200A Smart BMS & High Power Output】 Equipped with an upgraded 200A smart BMS supporting up to 300A peak discharge (10s) — ideal for running high-power inverters and motors. It automatically recovers from overload within 30 seconds, ensuring continuous operation. Reliable from -20°C/-4°F to 60°C/140°F, with charging cutoff protection below 0°C/32°F for added safety
- 【Certified Safety & Enhanced Protection】 Techex batteries are built with UL testing reports cells and an upgraded BMS with integrated heating pad to protect against overcharge, over-discharge, overcurrent, and short circuit. Features an excellent self-discharge rate, providing superior reliability and long-term peace of mind
- 【Smart Bluetooth Monitoring & Easy Setup】 Built-in Bluetooth lets you monitor voltage, SOC, temperature, and cycle count from your smartphone — no external meters required. Simple plug-and-play installation makes it user-friendly for DIY and professional systems alike
- 【Scalable System & Long Lifespan】 Supports 4S4P scaling for larger systems (e.g., 51.2V 1280Ah). Over 6000 deep cycles and a design life up to 10 years make it perfect for home energy storage, RVs, and other off-grid applications
