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.
Available upon request are small busbar segments to connect the modules in series. Also available are aluminum stands that the modules were originally housed in.
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.
Look at QNBBM 12V balancer for solution.

So how much are they? The problem that I see with paying for recycling upfront is that that cost today doesn't equal that cost in say 5 or 10 years. Good for you but potentially bad for the customer.
