Product Details

Hohm Base 4 Bay Universal Digital Battery Charger w/ LCD Display Screen

The Hohm Tech BASE is purely focused on precision, efficiency, consistency, and safety. It is a quad-channel independent lithium ion battery charger with universal algorithm to charge multiple battery chemistries. It has an advanced STN display to make viewing from any angle possible. This charger is equipped with a 4 button layout that makes operation and option selection quick and trouble-free. The BASE is compatible with most types of cylindrical lithium batteries ranging in size from 10440 to 26650 as well as Ni-MH, Ni-Cd, and LiFePO4 batteries.


Product Highlights:

  • 4 Bay Charger
  • .5A x 4, 1A x 4, or 2A x 2
  • LCD Display Screen
  • 0V Auto-activation feature brings cells back to life
  • Reverse polarity protection protects if cell is entered in the wrong way

Package Contents:

  • HO HOMETECH BASE digital battery charger
  • Standard USA power plug
  • User Manual
  • Warranty Card


  • The charger can charge different types and sizes with different capacities at the same time
  • mAh Detector: achieves current-state mAh capacity by using proprietary features of oscillation and micro-pulsing (charge/discharge)
  • 0V Auto-activation feature brings cells back to life
  • Backlit digital display showing battery voltage, charge/discharge current, charging time, battery capacity, etc.
  • Compatible with most sizes of cylindrical lithium-ion batteries ranging from 10440 to 26650, as well as NiCd and NiMh batteries
  • Compatible with Li-ion / LiFePO4 / Ni-MH / Ni-Cd Batteries
  • Each slot/channel is individually controlled by independent Intellichips
  • Four-stage charge/discharge algorithm (CC, CV, oscillation, micro-pulse)
  • Binomial DV algorithmic technology (pinpoint precision charging)
  • Tri-charge allows multiple charge/discharge rates: (0.5A, 1A, and 2A)
  • Up to any 2 slots can utilize maximum AMP RATE. Using all 4 slots triggers 4A distribution for efficient input-power distribution
  • BCM (Battery Chemistry Multiplier) is preset for simple & safe operation. Charge at 0.5A, discharge at 0.5A. Charge at 1A, discharge at 0.5A. Charge at 2A, discharge at 0.5A. BCSM (Batt Chem. Stress Match) is also 100% automated. It measures, monitors, and elevates any excess stress during oscillation and micro-pulse intervals to retain optimal +/- cycle.
  • LCD displays real-time status (charge %, volts, mAh, and cycle time)
  • mAh Detector: achieves current-state mAh capacity by using proprietary features of oscillation and micro-pulsing (charge/ discharge). Using this operation achieves real mAh at safe cut-off levels for battery cells
  • Battery Doctor: uses amplified oscillation and micro-pulsing current to bring batteries to their utmost AMP & capacity potential
  • Two-Tier Battery Bridge System. *Smaller batteries have dedicated groove inside each slot for secure placement
  • 0V Auto-Activation feature automatically handles any 0V situation. Put battery in, Hohm BASE will handle the rest
  • Overcharge & Overtime Prevention: Automatic safety feature cuts power to battery if the cell were to reach any of the preset volt values, binomial DV algorithm values, or time limitation values
  • Buzzer alarm to alert of any irregularity or battery error occurrence
  • AUTO maintenance charge if battery voltage drops .02V. *Leave battery in charger for a day or a decade...they will be ready when you are
  • 166o STN screen displays each batteries’ real-time status, properties, and condition from nearly any angle. *STN enhanced LCD display

Hohm Tech Base 4 battery charger August 10, 2018
Reviewer: Miguel Calzadilla from Divide, CO United States  
Hohm Base 4 battery charger works as advertised.  Recharges batteries fast at 2V but where it shines is battery doctor to bring back old batteries.  Only complaint is instructions are not clear.  Just as soon as you insert batteries push the buttons to change mode, and or charge rate.  If you wait you cant change them without taking the battery/ies out.  I would recommend this product for someone who has old batteries to see if you can bring them back to life or someone who want to start with  a good charger with potential to grow.

Nice charger July 1, 2018
Reviewer: Andrew Rock from Seattle, WA United States  
The construction on this charger is really good, doesn’t feel as utilitarian as most chargers.  Feature set is really good, I haven’t put a timer on it but I swear at 1 amp charge rate it’s charging my VTC6s back to full faster than my XTAR VC4 does at 1 amp.  My only con is that you have to cycle through each individually slot to adjust settings, would have preferred to just be able to select slot 4 instead of having to cycle through slot 1, 2, 3 first.  It’s nit picky but that’s really the only bad thing I have to say

Smart, fast charger June 27, 2018
Reviewer: Murray King from Oklahoma City, OK United States  
Needed a good charger for all my vaping and flashlight rechargeables. The Hohm Tech works great. It's fast and the Dr. Mode has helped restore capacity on some older 18650s. Only wish the tabs on the lower spring loaded contacts were taller to make loading and unloading easier. Money well spent.
