Please note: These batteries will require balancing and matching before they can be used in a battery pack, buyers of loose cells should be aware of the technical expertise needed to assemble a battery pack. We also recommend the use of supplemental resistance and or active balancers to ensure cells have equal charge.
All batteries have been load & capacity tested to ensure they meet manufacturer specifications of 290 AH (+/- 5 AH) and will have between 290 AH to 315 AH of available capacity @ 3.2v nominal while under a .2C discharge load at STP. The LF280K V3 variant is offered with laser welded stainless steel studs on the SFK high amp battery terminal, please note this terminal is rated for a maximum 300 amp sustained load and burst of of up to 500 amps (5 secs max).
