I have been searching online and nothing is making sense.I am making a 12v battery out of 4x 3.2v 135AH LifePO4 battery packs. I will have five of these 12v batteries in my battery bank.It is for my RV (recreational vehicle fifth wheel). I have 1240 watts of solar on the roofand the battery bank I'm addingwill be used to power 12v D/C and 30a/50aA/C loads (5000w inverter).
How do I know what amperageBMS to buy? I was told I should buy a 150ABMS by the seller of thebattery packs,but that doesn't make sense to me as that is more than the 135AH. I was thinking I should buy 120A BMS to be under the 135AH since it would use less of my battery overall.
Am I thinking about things all wrong?
Thanks in advance for any help provided.
