  1. Nick Yeoman (verified owner)

    Fantastic BMS design and working well, I’ve only pushed 110amps through it so far, it didn’t heat up more than a few degrees. Great product and great customer service from Muller Energy. Definitely going to buy another one for my next build. Highly recommended.

  2. Rob Ligthart (verified owner)

    Beautiful designed and complete package, just add cables (M8 or M6) and you have a fully functional BMS with BT, touch-screen display and active balancing that works!
    With the App you can fine-tune all the settings to your needs.
    Add a discharge-switch (lead is included) and you can attach your loads without sparks!
    In all a very well designed BMS that makes a 12 volt LiFePO4 installation a breeze.
    The best thing next to sliced bread!

    very ok

  4. Cameron

    absolutely perfect..mine is over 16 months old now.
    I regularly charge and discharge at full rated capacity and it’s been flawless ever since it’s installation.

  5. Allan Harley (verified owner)

    Exellent BMS very happy. Service is exellent its great to be able to talk to someone who knows his product

  6. William Donald (verified owner)

    Just successfully tested all this running at the same time off my 626Ah 2P4S battery and had 255 Amps running through the BMS. Only for a few minutes as I didn’t want to push it so early on:

    110 litre compressor fridge (about 5 Amps)
    water pump (a few Amps?)
    1550 watt air fryer (actually used more like 1700 watts)
    750 watt microwave (uses 1200 watts)
    Both those through Fchao 3000W inverter.
