Bigger battery bank

I was looking for more power for my house side of my bus. I had 4 L16 amg batteries. They just didn’t do it. So I started my search for “More Power” I looked at all 12v 400amp hour batteries made !!! Yes made ! Why did I go with LiTime batteries. Well the first point was cost I purchased them from their site litime.com they were running a sale I paid $912 per/battery if you bought 4. Yes that’s 1600amp/hours. With my specific set up it has two magnum 3012H inverters so I spilt the inverters so each had there own battery bank . Now to be fair li time was not my first pick like I said I looked at every 400amp/hr battery out there. There are ones with Bluetooth , and heaters to charge below 32*. Well my set up is kinda special ( 2020 Entegra Anthem) it has a special built in battery box that receives heat from my main living area . So heat was not needed. Second by making two battery banks I used two VictronConnect ip65 500v shunts to monitor the SOC. As you can see I didn’t need any of them fancy features I just needed power. I will be doing a in depth video for LiTime to be used on their web site. No I was not paid nor did I receive any compensation for this review . Take a look at Li Time batteries. If you just need power at a good price and the fancy features aren’t needed then theses are great batteries. I will be doing a one year review on their site ( if they ask me )
