Inspired Energy 10.8v 8.7ah 93wh w/ BMS - 9x 2900mah

Here are Inspired Energy battery packs. They are 10.8v 8.7ah 93wh with a 6.2a BMS and fuel gauge. The positive and negative allows for energy to flow in and out so you don't need any proprietary connection to enable current flow. Simply add 2 blades of nickel, copper, or brass in the positive and negative slot and you are all set.

95% of the energy is stored above 10v so you can absolutely use these with a 12v inverter since most 12v inverters cut out at 10v. Just set your charger or charge controller to 12.6v and you can parallel as many packs together of these as you want.

I am not sure what the connector type is, just use any blade to make your connections. Since these have a 6.25a BMS I would recommend running continuous at most 5a per pack. Just figure 55-60w of power continuous per pack. If you have a 500w inverter then use 9 packs in parallel. 1000w inverter you should use 18 packs. 

We only have 1 pallet so get them while they last. We tested 10 batteries and every battery tested above 95% of the original capacity.

Each module is made of 9x 2900mah 18650 cells and these are used in the medical industry so you know there are high quality cells being used.

Recommended Max continuous charge and discharge is 5a per pack. Yes these can handle much more but let's not try to burn out the BMS inside or cause any unnecessary heat. They're only $9. Build a pack large enough to handle your load without needing any cooling so stay under that 1c rate. 

The pack weighs 1 lb. Dimensions are around 3.5" x 6" x 1"
