In this Video i show the basics on how you would swap out your old lead acid batteries in the 48 volt configuration to Lifepo4. UPS is a Emerson GXT4-2000RT120 .
I will have to remember this video, Because I need to find some good Rack mounter Server UPS for my well server's, and network equipment. Be nice if they just make a 48 volt battery to just replace the 4 batteries. With LIthium being able to have up to 30AH in then same foot print of just one of those 12 volt battery's. Be nice to put a 48volt 20AH battery in place of the old lead acid so the UPS can last a lot longer during a power outage. But I do like this video. Also I wonder if they make those battery's in higher AH other than 6AH when most of those Lead acid ones are usually 7AH
I am about to do another video on building your own battery . Got all the cells in this week and will begin working on the video ! Also i will go over capacity and cell sizes There are some limitations but I'm going to try and make something work
Great idea. Very cool video. Do you anticipate any issues with how the ups charges the lifepo4. I would assume the ups still thinks it’s lead acid and keep them topped off all the time which lead acid like. Without being able to control the charge profile on the ups, the lifepo4 may get damaged or degraded prematurely. Can you do a follow on capacity in 6 months or a year? Thanks
Yes that sounds about right. Limited to the discharge capabilities of the BMS's. Still for the use intended it will be a hell of a lot better than lead acid
yea custom built pack would double the max output of 300ish watt or double the runtime whichever you choose to go with, if you can get cells at a price that isn't redicilous vs batteries , could probably fit 12ah in the same space, doubling the runtime well have actually seen a 12ah battery in that size but if this is all you need great stuff
I agree , Maybe ill try and get ahold of some 26650 lifepo4 cells and build a pack for a more advanced video , ill have to get another UPS , but i could always use more! Be good to do it and do some good testing for simulated outage.
