Here are awesome BMW batteries at Kia prices! These modules are testing consistently around 90% of original capacity which means these came off of very low mileage BMW vehicles. You can expect around 1350wh of energy storage. Its rare to find EV batteries with this much life left in them.
We don't have too many of these in stock so get them while they last. Just $100/kWh. We recommend using a Daly brand bms, 16s lithium ion. You have access to balance leads and also probably easier to just solder to the cells. You can see in the 2nd photo the cover pops right off and you have access to all the cells and busbars. You can connect to the main positive and negative with alligator clips as you can see in the 3rd photo. Or just solder to the busbars. Super easy battery pack to work with.
If you have an inverter that accepts up to 64v input this is a perfect battery for a powerwall. Of course since this is an EV battery these are great for EV, golf carts, forklifts, ebikes, etc.
