The Prohelion CMU suits any lithium cell chemistry of any form factor, as the threshold voltages are user-configurable and a simple wiring harness is used to connect the node to the cells.
Each node can monitor between one and eight cells, and is powered from the network, not the cells themselves, so the BMS itself does not contribute to cell leakage and imbalance.
