BMW OEM 5s 19.2v 75ah 1.44kWh Battery Module

Regular price $219.99 $0.00 Unit price per

OEM main positive and negative cables are included. Each module will come with a series connector which you can use to series or parallel modules, or you can cut it in half and use the connector on each end to make your connection to another device if you want. Every pack also comes with the balance lead connector. 3s and 4s modules will be available while supplies last so you can buy 2 of these 5s modules and a 3s module to make a perfect 13s 48v module. Or 2 of these in series makes a perfect 36v battery. Fully charge each module before connecting to top balance the batteries, then make your connections and add your bms. Many customers are using these modules for golf cart batteries and we have been installing them in forklifts in partnership with a forklift company so these really have been tried and tested. Also perfect for a powerwall but built for all applications.

As you can see in the 2nd photo showing the discharge curve these cells have a higher than normal nominal voltage based on the professional tests we've conducted. They hold a nominal voltage of roughly 3.84v per cell and 95% of the energy is above 3.3v per cell. 

This is the greatest deal you will find on BMW batteries. BMW batteries are very valuable because they are built like tanks and use Samsung NMC prismatic lithium ion cells.

This is an AMAZING option for the ultimate powerwall, EV conversion, golf cart, forklift, etc. These are from field trial 2012 BMW Active E cars that were only leased for 3 years. These batteries are all balanced and have a ton of life left in them. New these are 90ah, these still have around 80-90% of capacity as shown in the test results in the 2nd photo. All batteries were tested as a pack by BMW and then tested here again when we broke down the full modules.

The battery modules are beautiful and one of the most solid, well built modules we have seen. Holding one you can tell it is built to last. These use 45ah cells and are in 2p format. So the 5s module is actually 8 cells in 5s2p configuration.
