Question on switching to LiFePO4 batteries.

LiFePO4 is a different animal and while it has a few things you can't do like you did with your old fifty buck Walmart special, it isn't really that hard. little things like using a capacitor to preload your inverter circuit before you hook the batteries to it, on a new install, is it necessary probably not, but it does reduce the chance that feedback from a spark will take out any electronics.

even things like making sure you can parallel it, some can't, some have 2 battery restrictions some have 4. same goes for series installation, do the homework.

This is an interesting comment about the inverter. My inverter is currently connected directly to one of my batteries and doesn't go through the switch. I was planning on leaving it this way and see if I have a problem with parasitic draw drawing down the LFE battery when the switch is in the Off position. According to my inverter manual it doesn't draw any current when the inverter is switched off. If it did I was either going to disconnect it for storage or move it to the switch. I would hope the BMS can protect itself from the inverter inrush current. It is pretty common to have inverters connected to batteries and it seems like they would have precautions in the battery manual if it could harm the BMS.

My new LFE batteries are allowed to be connected in parralel but not series.
