Brand new (I have 2 new ones) These batteries are powerful and last for multiple games (I get around 10k shots on a full charge, 5k half charge) Perfect for high performance builds Doesn’t puff or fade, and tons of amps. Quick maths: 16c discharge x 6000mah = 96 amps discharge equivalent to: 100c 1000mah 67C 1500mah 50c 2000mah Plus more way more lifespan/durability due to chemistry differences Purchased new for $90 (81 +tax)
