I have 4 of those, they're kind of pricey, but I like how they keep their 'punch up' power right at full charge and how they are consistent through charge cycles. I just picked up these cheaper Gaoneng 1500mah 4s 80c/160c ones. Gonna see how they compare to the Tattu R-line ones. Don't think they are graphene though. Only ones I know are graphene are the Ahtec Infinity ones, but I haven't tried those.Gens ace 1550 4s 95c 2017 MultiGP Winner Battery – Tattu R-Line 1550mAh 4s 95C Test Review
I ordered 4 of the graphene ones and one of the LiHV ones. I then got an email that the order was returned to them asking if I wanted a refund or not. I replied for them to try and redeliver it, then they sent me an email a couple days later saying that they will be refunding my purchase. So then I just ordered 4 more of the Gaoneng GNB 1500mah 4s ones that I got from them before. A shame, I wanted to try both those other type batteries. Plus they were actually cheaper.I have had a multiple battery order split into packs of two batteries & shipped by road here in AUS for the “hazardous material” reason, how many did you order? Also, my batteries that were bought from BG were drop shipped from a warehouse here in AUS, even when I ordered only one.
