caption_attribution_description: English: Multiple Lithium Iron Phosphate cells are wired in series and parallel to create a 2800Ah 52V battery. Total battery capacity is 145,600 Watt hours or 145.6 kWh. Note the large solid tinned copper busbar connecting the cells together, this busbar is rated for 700 Amps DC to accommodate the high currents seen in a 48 Volt DC system.
context_page_description: The lithium iron phosphate battery or LFP battery, is a type of lithium-ion battery using LiFePO
  ₄ as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. The energy density of LiFePO
  ₄ is lower than that of lithium cobalt oxide chemistry, and also has a lower operating voltage. The main drawback of LiFePO
  ₄ is its low electrical conductivity. Therefore, all the LiFePO
  ₄ cathodes under consideration are actually LiFePO
  ₄/C. Because of low cost, low toxicity, well-defined performance, long-term stability, etc. LiFePO
  ₄ is finding a number of roles in vehicle use, utility scale stationary applications, and backup power.
