  • Top balancing my new lifepo4 cells

    Hi all! Today I received my new 4x lifepo4 280ah cells. I live on a boat and have 2x victron 100/30 mppt solar controllers and a sterling 20a battery charger. I want to top balance my cells from the generator and maybe the solar (its winter in the UK). I cannot really afford a bench power...

    Hi all! I'm a new member and live full time on a narrowboat in the UK.

  • Extending Daly Smart BMS temperature sensor?

    Hi all, In my setup I am unable to easily get the temperature sensor on the cells for my battery. Does anyone know if it is possible to extend the temperature sensor using wires, or will this cause a change to the value? Cheers!
  • Adding a new, different size battery to my lifepo4 setup?

    Hi all. Up until recently I have been using a 280AH Lifepo4 bank on my narrow-boat with a Daly 250A BMS. Over a winter and a year or so, I noticed that I did not give the batteries time to balance and they had eventually gotten so out of balance that I felt the need to do another top balance. I...
