    Purchased 200amp lithium battery pack, very happy and ran my air fryer oven. The Bluetooth is great to monitor the health of the battery.

    I am very happy to share my experience with Muller Energy, and their battery performance after buying two 200AH Lithium Iron Phosphate (LiFePO4) batteries from them in January, 2024. There were cheaper LiFePO4 batteries out there but I had the capital to go for the best I could find, and I think my research led me to that very outcome with Muller Energy.

    There was a shipping delay due to courier confusion, so Muller Energy sent me a 175 amp Anderson to Anderson connecting cable to join my batteries in parallel, free of charge, in compensation, and that was on top of a very decent discount for buying two batteries in the first place.

    I had some questions while setting up my system and was able to speak with Ruben Muller himself to have them answered, and I have to say, now that my setup (with three new bifacial solar panels, a new 240v/solar/alternator 30amp battery charger and a 2000 watt inverter) is complete, these batteries have exceeded all expectations.

    I believe the build quality is exceptional and the black stainless steel battery cases are as robust as you will find on any battery anywhere, and I love the remote display panel that each battery came with. I have them, and the remote display/control for the battery charger unit, mounted in a small pvc box that I can move around easily.

    I also have the battery management app on my phone that makes use of the Bluetooth connection built into each battery, and allows me the same monitoring capabilities from my phone with the addition of changing any of the multitude of settings in each battery’s Battery Management System (BMS), not that I have needed to as the initial Muller Energy BMS settings have worked perfectly.

    I was camping a few weeks ago and we had a 28 degree night after a 39 degree day and I had my Zero Breeze MkII Air Conditioner running all night at 20+ amps as well as my Engel fridge which was running 24/7 anyway, and I think my batteries were down to 50% in the morning with plenty more capacity still there if I had needed it.

    These batteries have an expected cycle life of between 2000 to 6500 cycles depending on Depth of Discharge (DoD), so with mine now showing 3 cycles after a few months of light use and one camp trip of pretty heavy use (it’s now April 2024), I reckon I am going to be enjoying their power storage capacity in my off-grid 12 volt system for a long time.

    On the technical side, I love the active balancing component of the amazing BMS that Muller Energy has adopted. This is far superior to the passive balancing that most BMS utilise. I believe (from my initial research) that the BMS manufacturer modified and custom built this edition of an already high quality BMS specifically for Muller Energy.

    So, to sum up, I believe Muller Energy is making the best LiFePO4 batteries out there right now, and if you are contemplating getting one (or more) yourself, then do yourself a favour, and get the best there is from Muller Energy.
