I would like to use Amazon because of free and expedited shipping. I bought one once that I put in and when I plugged it into assistant it said something to the effect of it not being a smart battery. It was purchased from DJI so I don't know what was going on there. I see the Ofeelys and limefuels but want to make sure I get one that is comparable and works so maybe I should stick with a DJI product. Do you have a recommendation on who to buy from on Amazon? The one I got the first time that had the not a smart battery message pop up had a model number that did not have PH2 in front of the number. I sent it back and got another one that did have PH2 in front of the model number. Have not had any problems with that one.
