I don’t think there is any difference between the BetaFPV and Crazepony 230mAh batteries. About 3 weeks ago, I purchased 8ea of the BetaFPV and Crazepony 230mAh batteries, and in my Beta65 and Beta65s, they perform almost identical from the beginning of the charge to the end. I suspect that they are the exact same battery with different branding. I get on average, 3:15-3:30 out of either brand on my 65 and a bit over 3 minutes on my 65s. I fly until the OSD voltage is 3.1V then land as soon as I can get it back to me. We’ll see how long they live at that discharge level but they are cheap so who cares
I did a little 230mAh battery smackdown about a week ago and as usual, every battery is a little different which is expected with such a low cost and (probably poorly) Q/Aed product.
I picked 3 batteries from each brand at random and charged them to 4.35V@.3A using a AOKoda HV 6-port charger. Then I discharged them with a iCharger 206b at a 4A discharge rate until a 3.0V cutoff was reached.
Here is the data:
On average, they all delivered about 245mAh with similar IR except for one. Oddly enough, it was the heaviest battery of the bunch but still performed about the same.
I really don’t think you can go wrong with either battery so I’d say pick the one that is cheapest on Amazon the day you purchase since Amazon changes prices as often as the stock market fluctuates!
