【Deep Cycle Battery】: CHINS LiFePO4 battery provides 2000+ cycles compared to 300~500 cycles in lead acid battery. The service life of LiFePO4 batteries is 8 to 10 times than the standard lead-acid batteries. The weight of the lithium iron phosphate battery is 30% lighter than the lead-acid battery of the same capacity. Brand: CHINS, Size: 20.47 x 10.59 x 8.66 inches, Color: Black, Orange, Item Weight: 70.5 pounds 【Lithium Iron Technology】: CHINS deep cycle lithium-ion battery has higher energy density, more stable performance and greater power. LiFepo4 battery will not burn when overcharged, overdischarged, overcurrent or short circuit, and can withstand high temperatures without decomposition. It can support fast charging and solar panel charging. Our LiFepo4 batteryis a green battery, it does not contain any heavy metals and rare metals and is more environmentally friendly. 【Built-In BMS & Convenience & Maintenance Free】: CHINS LiFePO4 battery has built-in BMS (Battery Management System) to protect it from overcharge, over-discharge, over-current, and short circuit with excellent self-discharge rate. Built-in high temp cut off prevents charging over 122 °F (50 °C). Plus, Li-Ion batteries can be safer than Lead Acid batteries, which have no protection against ground faults. This product fits for outdoor camping power and indoor easy installation. 【Bluetooth function】: Compared with the traditional battery monitor, CHINS lithium battery has added Bluetooth function and can obtain various data (SOC) of the lithium iron phosphate battery. Customers can connect to the battery through the mobile phone APP, and read the battery voltage, current and other important information at any time. Wireless connection range: within 5-10 meters from the battery. 【Widely Used】: CHINS lithium iron phosphate battery can be used in the following areas: Home energy storage system, UPS backup, lighting, digital/CCTV cameras, portable TV, e-Robot, electric vehicles, DIY loud speaker, air pump, fish finder, golf cart, trolling motor, motorhome/RV & camper, Houseboat, Travel Trailer, Dump Trailer and more. When the batteries are used in parallel, the battery voltage and capacity must be the same, and purchased in near time(within 6 month). 【Low temperature cut-off function】: The BMS inside the CHINS battery can automatically cut off the charging function in a low-temperature environment to avoid irreversible damage to the battery. Note: This battery does not have a low-temperature charging and heating function, and cannot be charged in a low-temperature environment. 【Capacity Expansion】: CHINS 36V 100AH LiFePO4 Battery does not support series connection, otherwise the battery will definitely suffer irreversible damage. Connection in parallel: it can connect multiple batteries, suggest no more than 8pcs in parallel. Allow to be extended up to 8 in parallel to get more capacity (Max 800Ah). 【Special Note 1】: If the load you are using contains trolling motor, the maximum continuous output current of our battery must be twice of the motor. Otherwise, our batteries cannot run your device. You can also consult us about this issue before purchasing the product, our engineers will give you the advice. In addition, our batteries cannot be used as a car starter battery Nominal Voltage: 38.4V Charge Voltage: 42.6V-43.8V BMS Board: 200A Peak discharge current(Duration: less than 5 seconds) : 1000A Dimension: 20.47 x 10.59 x 8.66 inches Weight: 64.55 lb Operating temperatures: Charge: 0°C~50°C(32°F~122°F) Discharge: -20°C~60°C(-4°F~140°F) Storage: -10°C~35°C(14°F~95°F) The setting method of MPPT and inverter of 38.4V lithium iron phosphate battery pack is as follows: Charging Charging Limit Voltage: 42.6V Over Voltage Disconnect Voltage: 43.8V Over Voltage Reconnect Voltage: 41.4V Float Charging Voltage: 41.4V Discharging Low Voltage Disconnect Voltage: 34.8V Low Voltage Reconnect Voltage: 37.2V Under Voltage Warning Voltage: 38.4V We live in an era of energy within reach.
