3 Pack Power Sonic 12.8v 45ah PSL-12450 - 1.7kWh

These are lifepo4 12.8v 45ah batteries. You get 3 batteries for this price. All of the batteries take a charge and cycle. These particular batteries the BMS shuts off at 12v by design instead of 10v. We have tested hundreds of these batteries and they are very nice overall, just keep in mind when and group of cells reaches 3v the BMS will shut down. All cells will have good voltage so you can always take the cells out and add your own BMS. Some packs the cells will be slightly out of balance and you can easily balance them again. For this price you are basically getting 1.7kWh of batteries for around $150/kWh. Plus you get the enclosures and the BMS. Or just just use them as is and make sure they stay above 12v.

To be clear, these packs all function like they should, just the BMS shuts off at 12v instead of the usual 10v. If you open the packs, balance the cells, add your own BMS, you should get near 90% capacity on average since these were just lightly used in hospital computer carts.

As you can see in the 2nd photo these are awesome cell packs using 18650 lifepo4 cells and as you can see in the 3rd photo you can cut the lid at the seam with a dremel. The whole battery pack will then slide right out. Also this pack uses JST connectors for the balance leads so they should plug right into most BMS units.

M6 bolts are included!

All batteries are checked to make sure they take a charge and the BMS is not shut off so they are all functional batteries.
