EARLIER this year we worked with eZee to produce a 48V option of their convenient flat rack mounted lithium pack, and are glad to now have a large quantity available and in stock now. The 48V 8Ah lithium battery is made from 3C rated Samsung cells and is a mere 3.3kg in weight, with a 25A output current capability. Sourcing reliable 48V packs has been an unexpected challenge for us over the past several years, but our testing on this one so far gives a lot of confidence. Discharge profile is shown in the graph on the right.
