Review: Great Little Package for the price. cool, simple charger. DOES NOT FIT LaTrax Alias Drone without modification to the battery holder.
Review: I previously stated that these batteries are unable to deliver 3 amps without dropping below 3 volts. I was wrong. The mating cables I was using in the test had excessive resistance. I don't know if they are really 25C, but URGENEX deserves 5 stars for their customer service. They refunded my money when I didn't even request a refund.
