Having done vigorous quality checking and testing to ensure that the batteries we use are absolutely reliable and work as well as a normal battery should. Gomi has decided to use second-life batteries for many reasons, the main two being humanitarian and environmental reasons. There are humanitarian and environmental issues around the materials used to make lithium-ion batteries. Especially around cobalt and lithium. After thorough research and testing, we found out that many modern mobility vehicles, such as e-bikes, have completely working batteries at the end of the life of the e-bike. They have to be put out of service due to issues with circuit boards or them coming to a fixed ‘3 year period’ where they have to replace a fleet according to contracts. Through rigorous testing, they have been able to use these batteries and ensure they have a capacity comparible to brand-new cells and are proud to say that they have been able to safely reuse and certify lithium cells from old mobility vehicles and incorporate them into all gomi products while passing the most vigorous lithium battery standards with flying colours.
