Arris 4S 1500mah 50C Graphene LiPo
Graphene LiPos started popping up a year or so ago, and I’ll be honest – I really didn’t care. I know what graphene is, and I knew it wasn’t really going into these batteries. I have no idea what they put in them to be honest, but after testing out a few brands I can say there is something different about them.
I picked up a pair of 4S 1500mah Graphene LiPo packs from Arris a few months ago and have been running them pretty hard and irresponsibly low. Just this past weekend I started a race at 15.5V, just to see how they would handle it. I’ll get back to that.
The Arris 1500mah Graphene packs are 90mm x 32xx x 25xx, which is pretty standard for a 1500-sized LiPo. weight-wise they are about the same as my old 40c Multistars, coming in at around 160g. They would probably be best on a 250-sized quad, but I’ve run them on a 210 and even a 200-sized quad just fine.
As I said earlier, I’ve been running these packs hard and taking them low to see how well they handle it and I am pretty impressed. I’ve got a dozen or so cycles on each and the most the cells have varied is 0.02V. Granted I balance charge at 1C every time (because I don’t like fires), but that is still pretty dang good.
In flight they give me plenty of power – I’ve never been left wanting for thrust when I needed it. Well, maybe once… That race I mentioned before? Where I started at 15.5V? Yeah, don’t do that. I was able to complete a few laps, but I really had to push the throttle to stay above ground. Thing is though, my voltage sag dropped to about 9.5V but never really any lower. I’m sure that LiPo will never be the same, but that was the point… In a pinch, the battery had the power my aircraft needed to do what I commanded. That little bit of power could be the difference between a catastrophic failure and a safely recovered quad. It also sets this graphene pack apart from some other brands. Other graphene packs I’ve tested are known for a lot of power up front with a harsh drop at the end. You’ll be up and flying around and them BOOM – no power. The Arris pack held its own until the end, and as a certain TV felon would say “that’s a good thing”.
Complaints? Well for one thing they are almost $40.00 a pack. Sorry, but I’m not a good enough pilot to justify that cost when I can get a similar battery for about $15 less. Don’t get me wrong, they are good LiPos, but that is pretty steep for a noob. That being said they held up better than any Multistar I’ve ever used, so if they continue to take the abuse the cost is justified because I won’t be replacing them anytime soon. Only time will tell!
- Plenty of power
- Smooth power curve
- Low voltage sag, even in the bottom end
- Cells stay balanced
- No problem bouncing back when taken to low voltage
