LithiumPower 12.8v 32ah 410wh LifePo4 Module w/ BMS
The bolts for the posts are included!
These are plug and play 12.8v 32ah LifePo4 modules with a medical grade BMS that were used in robots. The ones we tested have all been above 90% capacity, mostly between 27-33ah. The company swaps them out with new batteries every 18 months or when a battery reaches below 28ah and these batteries were not even used every day so these will last a very long time. The 3rd photo shows one of the professional tests we conducted on these modules which tested at 32.67ah. Although these are used batteries they have a ton of life left in them and perfect for solar storage and many other uses.
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.
This is the greatest value plug and play 12v module with a quality BMS. If you compare to the 40ah modules that are going used for $200-$250 and the 100ah modules used going for $450-$550 this one is a much better value.
At just 10 lbs with a handle these are perfect to take on the go, use for power chairs, camping, RV, and especially powerwalls. Yes you can series these into 24, 36, or 48v but you should use a 12v balancer/equalizer.
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)
