These modules have been recovered from Nissan Leaf batteries and then comprehensively tested and checked.

Specifications

Module Configuration: 2s2p (2 cells in parallel between the first and second terminals and 2 cells in parallel between the second and third terminals)
New capacity: 500Wh (~65Ah)
Nominal Voltage per cell: 3.80V
Operating Voltage Range per cell: 2.50V-4.20V
Recommended Operating Voltage Range per cell: 3.00V-4.15V
Maximum Discharge Current: 200A

Testing Process

Initial voltage check to quickly identify weak cells
Isolation check to ensure no internal fault causing a path to earth
Physical examination to check for evidence of damage or failure. Note that signs of swelling are not necessarily indicative of a cell with issues. Some mild swelling is normal for these types of cells. A module is classified as acceptable if it can be fully compressed when mounted.
Fully charge each cell
Internal resistance check
Full discharge test to record the exact module usable capacity (both sets of cells tested separately) over the 4.20V – 2.50V range
Charge to 3.80V storage charge ready for you

The results of the capacity and internal resistance testing are written on the module. If the module fails any tests it’s recycled and not available for sale.

Modules are supplied with bolts and machine screws for the terminals ready for use.

When placing an order you must select a capacity range and it’s guaranteed that the module(s) you receive will be at least the minimum value. For example if you order “90Ah-95Ah” then you might receive modules with 90Ah, 91.5Ah or 94.7Ah etc. If you have more specific needs then please get in contact before ordering to confirm exact capacity of the module(s) you’ll receive.

Note that unlike other suppliers all modules are tested.
