Ordered this charger to charge the batteries for the Fimi A3 quadcopter. To get more flighttime out of these Fimi A3 batteries, you need a LiHV able charger and this one fits the bill! Charges the A3 batteries via only the balance-lead much quicker than the charger that is included with the Fimi A3 quad, and in the 'LiHV' setting to a higher voltage too so you do get some extra flighttime. Charger does get (very) warm, so don't leave it unattended!
set for 2amps be aware would only be ok for 1000mah at 2c charge rate or 2000mah 1c . the h6 does lower amp for smaller packs ( I purchased this to cover 500mah 2s and up so not really suitable for my application )
