【Integrated Bluetooth, Real-Time Monitoring】Compared with traditional batteries, the LiTime 24V 100Ah Bluetooth LiFePO4 battery is equipped with Bluetooth function, and you can check the battery status such as battery voltage, current, battery capacity, and so on at any time through LiTime cell phone APP. Bluetooth connection range: within 10 meters of the battery.【Low-Temp Protection】The new improved 24V 100Ah Bluetooth LiFePO4 battery has built-in low-temperature charging protection, which automatically cuts off the battery from charging when the cell temperature is below 0℃ to prevent the battery cells from being damaged when charging below freezing point. When the cell temperature is at 5℃, charging is then restored.【Safe BMS & Excellent Cell】LiTime batteries are manufactured by Automotive Grade LiFePO4 cells with 100% 2560Wh energy, stable performance(2560W). Compared to a lead-acid battery, The A-grade cells provide superior performance and stability to the battery. They also have a built-in 100A BMS to protect the battery from overcharge, over temperature, over-discharge, over current, low temperature, and short circuit.【10x Efficient Charging & 2x Runtime】The maximum charging current of the LiFePO4 battery of 1C can reduce the charging time by 10 compared to charging an AGM battery (usual charging current: 0.1C). For better long-term battery performance and a longer service life, a charging current of 0.2C is recommended. LiFePO4 has a higher efficiency and a longer runtime after charging.【Environmentally Friendly and Wide Application】LiTime LiFePO4 battery is the latest generation of battery technology, so it does not contain toxic substances and heavy metals. All LiTime batteries meet UL testing, CE, FCC, and IP65 certifications. With IP65 waterproof and dustproof, lithium batteries are perfect for solar home, camping, RV, trolling motor, and off-grid applications. Note: Recommended for a 24V trolling motor with 70~100lbs thrust.【Fast Delivery Time and Professional Customer Service】LiTime has local warehouses in the United States, so we have super fast delivery time. In addition, LiTime offers a 5-year warranty, safe and solid packaging, professional technical support, and online customer service with quick response within 24 hours.【 ABYC Official Certi.】All LiTime marine batteries meet ABYC standards, ensuring the highest safety for your sailing needs.【Note】Upon initial use or after manually powering off the battery, please ensure to connect the charger to turn on the battery.
