Ask a question about this product




The MK3x8 is an eight channel Lithium Ion Regulator like our Mk3x4 four channel regulator.  With the change from through-hole to Surface Mount we have been able to decrease the per cell price and shrink the size from 8x4 inches to 6.9x2.4 inches with twice the channels.  It has the ability to run on as few as 4 cells and any number up to 8. The MK3x8 dissipates 2.5 amps per channel speeding up the eqaulization process.


-TEMP SENSOR KIT: Includes mating connector, contacts, heat shrink, and 8 temp sensors, or UPGRADE with the drop down menu to purchase the fully assembled 3ft harness.  You just cut the wires to length and attach the temp sensors.

*OPTIONAL*-TEMP SENSOR HARNESS: Includes fully assembled 3 ft harness with mating connectors and temperature sensors installed, ensuring proper temperature readings for your BMS.

-VOLTAGE HARNESS: Includes fully assembled 3ft harness with mating connector, just cut to length and add ring terminals (RING TERMINALS NOT INCLUDED)

For additional products such as a fan, extra harnesses, communication cable, modular jacks, and crimpers please check out the Regulator Accessories section of our website.


- Manzanita Micro gave us an awesome HUGE charger (PFC50) and provided a great BMS (using MK3x8s) for our battery pack. (The BMS just plugged in and worked perfectly. Nifty color-coded LEDs tell you exactly what is going on. Plug in your laptop if you want the detailed info on a cell level. Plugs right into the charger. Awesome.) - Eva Håkansson and the Electrocat



· Real time voltage monitoring of 4 to 8 lithium cells

· Real time temperature sensing of up to 8 external temp sensors

· Additional temperature sensor included on BMS module’s heat sink to prevent regulator from overheating

· Small size is less than 1 inch thick and 7 inches long by 2.4 inches wide

· Quick automatic cell equalization and balancing with high and low voltage on board indicators and outputs to the charger

· Two high speed real-time warning lines which can be relay buffered for external use

· All BMS modules connect together using readily available RJ cable

· BMS easily connects to a PC using the DT USB adapter (Dongle/Terminator sold separately)

· Free Windows based scanner and command software available for download at in the download section under MK3 Reg Support.

· All commands are easily entered and read in simple ASCII text

· Easy user adjustable min and max voltage parameters allow flexibility for various types of lithium cells from 1.75 to 5.5 volts per cell

· Each BMS board can bypass up to 2.5 amps per cell equating to fast charging and equalization of unbalanced cells

· Dual RJ reg bus ports for easy connection to the charger or other BMS units in a simple daisy chain fashion

· Self regulating thermal protection and feedback to Manzanita Micro Chargers

· Built-in active variable speed 12V DC fan control output on each BMS unit. The fan settings can be viewed and changed using the software found on our website

· Large heat spreader is totally isolated from the cells and is already threaded for easy mounting to a larger heat sink.

· Each unit can dissipate up to 110 watts
