Hohm Tech Hohm School 4A Charger

Thinking outside the box, while keeping simplicity and user-error prevention at the forefront with safety features. 18 months of R&D led us to develop an extremely capable charger that makes other chargers look stupid. It has a 3-tier amp BLD (battery length detection) System; has a variable input voltage IPR (input power regulator) feature. This ELIMINATES USER ERRORS, and keeps them and their li-ion batteries moving forward without delay. This is simplicity at its best, while not forfeiting usable amperage or precision.

There is no need for a screen on this charger. It is 100% autonomous. It is equipped with our BLD1 System, which automates the step up/down output so both small and larger cells charge at proper rate (0.5A, 1A, 2A per channel with 4A total distribution). Even li-ion batteries with a 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.

Disclaimer: Please use extreme caution when working with Li-Ion (Lithium-Ion), LiPo (Lithium-Ion Polymer) and any other rechargeable batteries. The user should have fundamental knowledge of batteries and battery safety before using these types of batteries to avoid injury. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. Do not use any rechargeable battery as well as any battery charger if any visible damage is present, as well as if the cell or charger has been stressed through mishandling or accidental causes even if damage may not be visible. Always store and transport rechargeable cells in a safe, non-conductive container in a controlled environment. Dispose of all battery cells and chargers in accordance to local laws and mandates. We will not be held responsible for any damage or injury caused by misuse or mishandling of Li-Ion, LiPo and any other rechargeable batteries.
