Hohm School 4 Bay Battery Charger by Hohm Tech
USB-C 4 AMP continuous power supply and stability made it possible for Hohm SCHOOL4 to do what it does so well.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 today’s small li-ion batteries chemistry integrity is not compromised, allowing them to get the cycle life they deserve.
Applying more forward thinking targeted towards safety & performance, we integrated input voltage regulation. This is safety 101 here. This allows charger to not stress or damage USB adapters no matter the power supplying device. Fact is simple: today’s li-ion batteries need precise voltage and amperage delivery to ensure long reliable performance & life…Say hello to Hohm SCHOOL4, the ‘Professor’ of Chargers.

Frequently Asked Questions
Yes. All cells we sell are guaranteed authentic, Grade A, and brand new. Not reclaimed, used, or rewrapped. We also prioritize fresh manufacturing dates, so you’re not receiving cells that have been sitting around for years.
Some sellers offer Grade B cells that can have inconsistent voltage, higher internal resistance, reduced performance, or other issues. You will never receive a Grade B, reclaimed, or used cell from us.
These are sold as bare cells (no welded tabs or leads) unless the listing explicitly states otherwise.
To make pack building easier, our cells are sorted and batched for matching internal resistance, voltage, and date code, so they arrive ready to be assembled into a pack.
U.S. orders ship from Atlanta, Georgia.
For international orders outside the USA, we may ship from a different fulfillment hub depending on the product’s manufacturing location, to ensure faster and more efficient delivery.
