Our OBD2 to Leaf battery adaptor, is designed to allow communication with the lithium-ion battery controller (LBC) in a Leaf battery pack when the complete battery pack has been removed from a vehicle. The most common use for this is checking parameters like last recorded state-of-health on a used battery pack prior to purchase. It can also be used to re-code or firmware update the LBC without any need to open the battery pack. We have two plug-in battery connector options. The 22-pin adaptor suits Type A battery originally fitted to model year 2011 or 2012 Leafs. The 36-pin adaptor suits Type B battery packs from 2013 or later.
