Sparks, Nev.-based Battle Born Batteries has released a white paper study outlining the performance details of its 100Ah 12-volt lithium-iron phosphate batteries and how they discharge in varying cold temperatures.
Battle Born Batteries conducted the study at various temperatures and shows that Battle Born LiFePO4 batteries outperform lead-acid AGMs batteries at every temperature.
For the room temperature results on both a 30A and 80A draw, the LiFePO4 batteries surpassed the AGM bank consistently. At a 30A draw, the LiFePO4 batteries delivered 207Ah out of 200Ah, where the AGM delivered 63Ah out of 210Ah available. The AGM battery bank was only able to deliver 30 percent of the advertised 210Ah useable power compared to the LiFePO4, which delivered more than 100 percent.
At an 80A draw, the LiFePO4 batteries delivered 191Ah out of 200Ah, where AGM delivered 11.3Ah out of 210Ah available. That means the LiFePO4 bank delivered 95 percent more power at an 80A draw than the AGM bank.
“The point of this study is to demonstrate that even though our lithium-iron phosphate batteries have a low temperature cutoff, you cannot extract or put in current into a similarly sized lead-acid or AGM system at cold temperatures,” the white paper states.
