Connecting two 12V batteries -BMS question

[Just John]

Hi,

Im a newbie to this forum so please bear with me!

I'm considering building a couple of 12v 100ah lifepo4 batteries which will fit under each of my front motorhome passenger and drivers seat (around 1m centres) as per my current lead acid set up. The current setup is as per the attached picture and I wanted to ask if this is possible/correct for my proposed lifepo4 batteries?

I also am not sure if I need 2 x 4s 12v bms modules or is there a 8s 12v which I could use??

Your help is very much appreciated

I suggest that you look at the reviews @Will Prowse has done in the past year on available batteries in the $300 to $400 range. Most are available from Amazon and are cheaper than a DIY build, and will work just fine.

I see most have gone up substantially in price, but look for them to go on sale regularly. Examples:

Thanks for that, are the reviews easy to find?
