Battery Lithium Iron Phosphate LiFePO4 25.6V, 100Ah, 2560Wh. Lithium iron phosphate battery with exceptional durability, energy efficiency and charging speed for a wide range of applications  Features:  The new generation of lithium iron phosphate batteries offers high energy efficiency (up to 94%) and a wide operating temperature range. They are fast-charging, fully sealed (can be used in any position) and compact in size. As an energy storage system, the LiFePO4 battery is very environmentally friendly and has a wide range of applications. Compared to lead-acid batteries, LiFePO4 outperforms them in terms of durability (lasting up to 25 times longer), weight (twice as light) and high current capacity. This type of battery is non-flammable and non-toxic. LiFePO4 batteries have a very low self-discharge rate of 20% of their capacity in more than 10 years. With smart BMS battery protection: protection against over-discharge and short circuit, battery charge and discharge control; voltage and current level monitoring; temperature monitoring, overload and overheating protection. Areas of application: backup power supply for uninterruptible power supplies (UPS), vehicles, lifts, caravans, boats, solar and wind energy systems, street lighting, power tools, appliances, toys, emergency power supply, etc. Important: LiFePO4 batteries are equipped with a built-in BMS (Battery Management System) that protects against over-discharge. When the battery voltage drops below the preset threshold, the BMS disconnects the battery output. In this case, use only a charger designed for LiFePO4 batteries that immediately applies charging voltage. Chargers that first check the battery voltage before charging may fail to detect a BMS-disconnected battery and will not start charging.  Specifications:  Capacity: 100 Ah (2560Wh).
