For applications requiring a long life in cycling, even sometimes at rather high temperature, ARTS Energy proposes a large range of Lithium ion (including LifePo4), from 0,5Ah till 3,3Ah. These cells are very robust and have an exceptional life time. They are mainly used in back up and solar applications for their long life time. ARTS Energy is not a Lithium-ion cell distributor as these products should only be used by professional and recognized pack makers. These cells are fully available in ARTS Energy battery packs
