Special circumstance battery sale.
These batteries are being sold with the price of recycling included in the cost. When the batteries come to the end of their life, there is going to be contact information on the module to call and set up recycling.
The easiest thing would be to get the module to any of our facilities, and we would take care of the shipping.
We are selling the modules in bulk orders only.
Minimum purchase quantity will be 8 modules. The reason behind this is for easier recovery for recycling.
BMS is hooked up and in standby mode. Software is available to look at Individual Voltage Cells, Temperature, SoC, Charge Cycles, Warnings, Faults, and Highest Current, Voltage, and Temperature History.
BMS will automatically balance the cells within one module during the top of the charge. Will not balance between modules when hooked up in series, only in parallel.

I have used these in 4 solar systems so far without issues. They have between 100Ah and 120Ah and are easy to hookup in series or parallel. A few issues with the M8-1.25 terminals needing threads cleaned up with a tap, no issues other than that.
I did end up using separate battery balancing bridges on the systems where I’m running 48V as I was seeing some charging differences between the batteries in series.
The batteries are packed securely for shipping and easy to handle.

Currently have 16 Valence U27-12XP LiFePo4 batteries in our off grid solar setup. Connected to a 30kw split phase 48v inverter. We run whole house including central air. Will get more batteries as soon as we are able.
qick delivery and well packed on pallet.

We have 28 Valence U27-12XP LiFePo4 batteries in two solar battery backup systems. Aside from a few issues with battery terminals (M8x1.25) needing to be tapped out, they are working well.
The batteries held charge while stored and all have around 100Ah of capacity.
They shipped on sturdy pallets and are easy to handle with a built-in carry strap.
