BEWARE !! Capacity not as described, received 18x 18650 which won't charged more than 2995 mAh for the best one. So these are not 3000 and even less 3300 mAh. I tested it with an original SkyRC Imax B6 with a full cycle of charge/discharge/recharge at 0,5 A (wich took each time a day and a half to complete). Also confirmed with an Opus C3100 charger. The seller and AliExpress will reject all your evidences and ask for specific procedures and thousand dollars professionnal material to prove the capacity or you will never get back your money. Go buy other batteries than Lanzhd and pay buy PayPal of you will lose your time and money.
