LithiumPower 12.8v 32ah 410wh LifePo4 w/ BMS - Fully Tested
These are plug and play 12.8v 32ah LifePo4 modules with a medical grade BMS that were used in robots. Every battery is fully tested and comes with the printout of the test results showing the graph and capacity. You can choose the tested capacity range from the drop down menu.
The one in the drop down menu that says "salvage/unbalanced" are modules that cut out early on charge indicating a group of cells is out of balance. You can cut these open to salvage the cells and the BMS. It is also possible that you can balance the pack again as is by charging each group of cells fully one at a time. Either way the value is there even if you just salvage 3 out of 4 groups of cells, the BMS, and the enclosure.
Specs show max charge and discharge current of 32a. A good rule of thumb would be 250w of power per battery. If you have an RV with a 2000w inverter you should parallel 8 of these together. Simply charge each module fully, make your parallel connections, and you are ready to go. It doesn't get any easier than this.
At just 10 lbs these are perfect to take on the go, use for power chairs, camping, RV, and especially powerwalls. We do not recommend series connecting these into 24, 36, or 48v because we don't have data on these to confirm however we have had many customers do that successfully. If you do that make sure to top balance the modules and also operate within a limited voltage range and utilize the 12v balancer/equalizers on the market.
Dimensions are 5 1/8" deep, 7 3/4" wide, 6 3/4" tall which includes the post height.
Overcharge cutoff is 14.6v (3.65v per cell)
Discharge cutoff is 10v (2.5v per cell)
We also cover the $37 hazmat fee and UN/4G packaging which is required for all lithium batteries above 300wh. We are fully certified to ship these.
