My motorhome is 5-years old this July. I've been on the hunt for new batteries, not so much mine are failing, but due to their age. I currently have 4-100aH AGM deep cycle batteries and not had any problems with them. I do think they are not as strong as they once were.
For my kind of "camping" I'm sure I could do fine by just replacing them with another 400 aH of AGMs and maybe get another 5 years from them.
But I want to improve my battery bank not just maintain it. So, I've been looking at LOTS of different Lithium Iron Phosphate battery options for quite a while. The other day, I was ready to purchase some Chins 200ah batteries at $730 each. But they didn't have low voltage charging cut off built in. So, I was trying to decide how to compensate for that.
Then today on Instagram (of all places) I get an ad for $300 off of 200ah Renogy LiPo batteries with Low Temp charging cutoff and Bluetooth monitoring. With the discount the 200aH batteries are now $999 with free shipping and 5% off for new customers So, $949.05 each. 400aH for $1899.98 delivered. Under $2,000 was my budget. To replace my 4-AGMs with identical would have been about $1,250. But I think this is a meaningful upgrade.
I trust the Renogy brand more than Chins, plus they ship from a US warehouse and have the batteries in stock.
I had already planned how to install them and what steps to take. I have even taken extensive photos of the current battery wiring and have a PDF of the wiring layout from Winnebago.
My next step will be to figure out the DC-DC charger (Victron for sure) and how it gets wired in. Should be a fun project.
PS. They gave me a code which will take 7% off of your order. It's up to you if you want to use it or not. I'm not pushing it:
