Need big capacity but have limited space? The ATEM POWER 200Ah slimline lithium battery is designed as thin as a "blade", making it the ideal slimline lithium iron battery in the case of the tightest of spaces to fit where other LiFePO4 batteries can’t. This slimline lithium iron phosphate battery is only 6.25cm thick, so you can mount it behind or under a seat or at the back of your 4x4. Built using A-grade prismatic cells that are less prone to failure, this battery also stores 2~3 times the energy of AGM batteries of similar weight. It is perfect for use with caravans, camper trailers, motor homes and 4x4 and provides a reliable energy source for camping fridges and 12V lights, etc. The SPCC enclosure, manufactured to Japanese standard JIS G 3141, is 20% stronger than typical hot rolled steel to protect battery cells. It is protected by high quality BMS, allowing peak discharge current of 300A and continuous discharge current of 150A, powerful enough to run high wattage appliances.
  • Fit Where Others Can’t: The super slim blade profile (6.25cm in thickness) makes it the perfect battery to be mounted behind or under seats or at the 4x4’s back.
  • A Grade Cell: It is composed of A grade prismatic cells that provides higher energy density and consistency and is less prone to failure caused by vibration.
  • Longer Lifespan: This slimline lithium iron phosphate battery can deliver up to 2,000 rounds — several times the life of a lead-acid counterpart.
  • Higher Usable Capacity: AGM are recommended to be discharged to 50% of the capacity while this lithium ion slim battery can be discharged to 80-90%.
  • High Quality BMS: It allows a Max. 300A discharge current and provide voltage/ temperature monitoring and smart balancing with a low self-discharge rate.
  • High Power Output: It has been designed to allow sufficient discharge amp rating to power high power appliances such as a microwave or coffee machine.
  • Faster Charging: Lower internal resistance allows this 200Ah slimline lithium battery/slimline lithium iron battery/ to be charged and ready to use much faster.
  • Optimally Engineered: Volt meter displays LiFePO4 battery’s capacity and voltage, and twin 175A Anderson style plugs for high current charging & discharging.
  • Impeccably Lightweight: Weighted 28.4kg, it provides 200AH that doubles the power of an AGM with half of that weight,even SPCC steel enclosure is equipped.
  • SPCC Enclosure: Made of Japanese standard SPCC steel, it is 20% stronger than typical hot rolled steel to better protect battery cells with glossy surface finish.
