After 11 month of R&D on the operations and features; we present Hohm SCHOOL 2A. What is the 2A? It's two things: 2 x bays & 2 x amp (2A combined output capability). It is 100% autonomous. It is equipped with the BLD1 System, which automates the step up/down output so both small and larger cells charge at proper rate. Even li-ion batteries with or without PCB/PCM3 are easily balanced to the correct voltage. This ensures todays small li-ion batteries chemistry integrity is not compromised, allowing them to get the cycle life they deserve.
