For sale are Valence U27-12Xp Lithium Iron Phosphate (LiFePo4) batteries.
Voltage: 12.8V
Capacity: 138Ah, 1.7kWh
Max Current: 300A (3.8 kW), 30 seconds
Continuous Current: 150A
Asking $400 each, I'll cut deals for batch purchase only.
6 are available.
Location is Dallas, TX - I'm willing to drive a reasonable distance to deliver or meet you, just reach out and let's talk if you're interested. My understanding is that shipping them is going to be quite a headache, but there might be a way. I'm open to ideas.
My brother has more of these up in Colorado for sale but I'm not certain of the exact number.

These batteries are used and I came to them by salvage. They came out of a Electric Box Truck with <40k miles. Based on some conversations with the folks who made the truck, the Depth of Discharge was likely pretty shallow in the ~50% range. The range of the truck was ~150 miles, so they've likely seen somewhere in the 400-600 charge cycles. LiFePo4 are said to fall to 80% capacity somewhere around 2000-3000 cycles.
I haven't directly tested the capacity of these batteries as I don't have good equipment to recharge them. The voltage of all 6 are in the healthy range and the built in BMS board is giving a green flash, indicating that batteries are in working condition.
Each battery has it's own internal BMS board. Without connecting to any other hardware, this board will perform passive balancing on the 4-series cell blocks within the battery. If you wanted to connect an external monitor, each battery module can communicate current, voltage and temperature over an RS-485 bus. Batteries can connect together and be monitored together. I have not personally verified the RS-485 functionality but I've spoken with someone who salvaged a similar truck and they were able to communicate with the cells using off the shelf hardware.
I've explored a few options for projects that I might have used them for (EV conversion, solar storage bank) but none were a great fit for my living situation right now... so I want to get them into someone's hands who can use them!
