I have been using Dinogy for over 6 months , and love them . They have good punch that lasts to 3.65v , then starts to drop off. The price on Dinogy has been creeping up. I saw Eachine 1500 for sale for 30% cheaper than Dinogy, I took a chance , and OMG a very nice battery. They behave different to the Dinogy. The Eachine has a little less punch but and stops at 3.50 v, Eachine dosent like below 3.6v, a few time my quad has dumped with no warning before the 3.5v low volt alarm . Eachine has rated this battery at 35c 1500mah, I think Eachine under rated this battery, It must be around 45c compared to Dinogy 65 c, and when charged the Eachine has a suprise , it charges to over 1400Mah consistantly, the Dinogy charges to 1300Mah. I like my Dinogy and if the price comes back to $32 AUD I will buy them, untill then I will try and find another place to buy the Eachines for $26AUD , BangGood dose not ship Batteries to AUS anymore.
