From the project

An inline protection board for replacing 2S NiMH/NiCd packs with 2S LiPo/LiHV, built around the Analog Devices LTC4368-1. NiMH tolerates being run flat; LiPo/LiHV does not. This board adds the low-voltage cutoff those older packs never needed, plus reverse-battery and bidirection

An inline protection board for replacing 2S NiMH/NiCd packs with 2S LiPo/LiHV, built around the Analog Devices LTC4368-1. NiMH tolerates being run flat; LiPo/LiHV does not. This board adds the low-voltage cutoff those older packs never needed, plus reverse-battery and bidirectional overcurrent protection, between the battery and the existing load.

Pack-total sensing on the two main leads only — cell balancing is handled by the charger via the balance lead. Adapted from the ADI DC2418A demo board, rescaled from 24 V / 10 A to a 2S (6.0–8.7 V) pack.
