Sourcing and delivery under one contract
MP-BMU collects cell data and sends it to the master through an isolated isoSPI daisy chain. It supports passive balancing and measurement fault monitoring. This is a BMS component, not a complete battery or standalone power protection device. Cell voltage accuracy requires clarification because the documents contain ambiguous units.
