Best bms to use

[Daledevon]

I am installing 2 diy lipo batteries in my RV. I am also installing a renogy 200watt solar kit. I know I need a bms and also want a good monitor. I'm looking for suggestions and prefer something reliable and easy. I also prefer cheap of course, unless this is better off going more upscale. I'm a newbie.

You should consider LiFePO4 batteries, they are far less exothermic than LiPo.

That shows that I am a newbie. My batteries are lifepo4.

You should watch the newbie videos then:

Go to the "more..." menu, then "Videos" and have at it.

I suspect you will have many of your questions answered and more importantly be able to come back here with specific questions.

Okay, I have watched a bunch including one where he compared different bms. I also watched the one where it had low temp cutoff. Specific question, since I will have 2 batteries, do I need 2 bms or is there one that works for both.

Yes you would need 2 BMS if the batteries are separate.
