LiitoKala 12.8V 40Ah LiFePO4 Battery Pack - 512Wh Deep Cycle Solar Storage Battery for UPS, Inverter, RV & Off-Grid Systems

Product Description
Revolutionize your energy storage with the LiitoKala 12.8V 40Ah LiFePO4 Battery Pack! 🚀 Unlike traditional lead-acid batteries that struggle after just a few hundred cycles, this advanced Lithium Iron Phosphate (LiFePO4) battery boasts an incredible lifespan of over 4000 deep cycles. 🛡️ With a total energy capacity of 512Wh, it provides reliable, stable, and clean power for all your essential devices. Weighing only about 3.7kg (8.1 lbs), it is a lightweight, highly efficient, and eco-friendly replacement for heavy AGM or GEL batteries. Built with an ultra-durable ABS casing and an integrated Battery Management System (BMS), it offers top-tier safety, ensuring you never have to worry about overcharging, over-discharging, or short circuits. Whether you are powering an off-grid cabin, an RV, a solar setup, or a UPS, LiitoKala is your ultimate power partner! 🔋⚡

Key Features 🎯

• 💎 Exceptional Longevity (4000+ Cycles): Delivers over 4000 deep cycles (0.2C) before capacity drops to 70%. That’s up to 10x longer lifespan than standard lead-acid batteries!

• 🛡️ Advanced Safety & BMS: Features a built-in, intelligent Battery Management System (BMS) to protect against overcharge, over-discharge, over-current, short circuits, and high temperatures. The rugged ABS outer shell provides added impact resistance.

• ⚡ High Performance & Power: Supports continuous 40A discharge and 80A pulse current (<3s), providing huge energy bursts for inverters and motors. The fast 10A charging allows for rapid recharging from solar panels or grid power.

• ❄️ Wide Operating Temperature: 10.0V discharge cut-off and a broad working temperature range (Charge: 0~45°C / Discharge: -20~60°C) makes this battery reliable in both freezing winters and hot summers.

• 🔋 Extremely Low Self-Discharge: With an ultra-low self-discharge rate of ≤3.5% per month (at 25°C), the battery retains its charge even when stored for long periods without use.

• 💪 100% Drop-In Replacement: At just 3.7kg, it is 1/3 the weight of a comparable lead-acid battery (which can be over 10kg!). Easy to handle, install, and transport.
