All makes sense. Thanks everyone! I was looking at 12V 200 AH batteries. The numbers were approximately as follows: one 10KWH 48 volt battery was around $3,400 with shipping (brand was BCS and didn't see much information out there about them...other brands were a bit pricier). .....four 12volt...

I am new to this. I just purchased an all in one inverter/charge controller. The charge controller is 48V. To save quite a bit of money, I wanted to use four 12V batteries connected in series. Is it ok to have a 48V charge controller connected to four 12V batteries in series? I know that the...

Thank you. I must say, I have read this response a few times and I am still completely confused by it. Can you expand on the explanation? What is the max voltage that I should look for to charge properly?

I posted a similar question in another area and think I should have put it in here. Here is the story, I bought an all-in-one charge system/inverter. The internal charge controller is 48 volts. The inverter is 48 volts. I am looking to save quite a bit of money on the batteries and found that...

Thanks for the responses. I am planning to use something like four 12v lithium batteries....maybe a Zooms Lifepo4 with 200AH. I thought it would work, but was afraid th 48 volts coming in from the charge controller and did not want to make a mistake. I will look at the battery specs before...

Yes, it does clear things up a bit. Am I understanding correct that maybe the reason to not use the 12v batteries in series is because, when the batteries are running low, I wont be able to use them for my 48 volt system?
