I don't have any 650's. I don't plan on running 650's on these kwads. But, with the setup I have on these kwads, the 650 would definitely give less flight time. And a smidge more power. Not enough to be worth sacrificing at least a quarter to a third of the flight time.
@@MrSmithFPV Either way, you can't go wrong with Tattu batteries. They are more expensive but they do give a bit more punch compared to cheaper batteries. If you take care of them they will last a while. I have some R-Line 1.0 batteries that I have had for three years and hundreds of flights on them. The 2.0 and 3.0 I think are just a bit better and are a little lighter.
@@MrSmithFPV What are the specs of your kwad? Or, is it a specific model from a company? You have to be sure whether or not it could handle an 850 (power to weight ratio). Adding the extra weight of the 850 could be futile in the effort to get more flight time. Every gram matters. The more weight added, the more power it needs to get in the air and the more Amps it will draw trying to maintain flight. Too much weight and it will handle like a brick and end up frying components.
Hey i just got these batteries, whats the storage charge setting for these? what should the end voltage be? and at what charge current is best to be used? thanks.
First of all, use a good charger that has charge, storage, balance, discharge functions. I personally use the Hobbymate D6 Duo Pro. These 4S 850mAh specifically: * Do not run these down below 3.5V per cell. It can damage the battery. * Storage Voltage: 3.80V to 3.85V per cell. (I usually set the cell voltage to 3.82) Balanced as close to each other as possible. - total voltage of all four cells 15.2 to 15.5V * Charged Voltage: 4.2V per cell - total voltage of all four cells 16.8V * Charge Rate: 1C to 2C Max. 1C is 850mA. I charge mine at either 1C 800mA to 900mA (my charger does not do 850) or if I'm in a rush I charge at 2C which is 1700mA (usually I do 1600mA). My typical settings on my charger for these batteries are: To Charge: 4S / LiPo / 900mA (0.9A) or 1600mA (1.6A) To Balance or Storage: 4S / LiPo / 900mA I use balance mode on my charger for my batteries frequently; usually after a few uses and especially if they will not be used for more than a couple days. Most LiPo batteries can be charged at 2C safely, but look at the manufacturer's recommendations to be safe. (1C is the capacity of the battery) NEVER leave your batteries unattended when on a charger and try to do it in a safe place where it is a minimal fire hazard. I am hoping to do a battery care video at some point, I just haven't had the time. Any other questions, feel free to ask.
@@therccrashproject6330 thats an amazing reply, thanks so much, very new to this. I also got the 18650 3000mAh SONY VTC6 4S 14.8V 4S1P XT30 from flywoo, are 18650’s normally safer than lipos????
@@7LETITBE7 Maybe just a little bit safer but not by much. They are still lithium batteries with the same risks. Just note that the 18650 (Li Ion) batteries are not high draw batteries like the LiPo batteries; they are not really designed for freestyle or racing kwads (drones/quadcopters) whatever you want to call them. Li Ions will burn up or explode when put under the high draw demands of freestyle and racing drones; that's why we use LiPo's. I just use Li Ion packs for my goggles. And you can use them in transmitters, etc. that are designed to use them.
Yea, I saw that. Big hands and small camera don't mix. I was using a very small camera and I had forgot to bring the grip I have for it. Oh well. Incidences Transpire.
What do you store them at? R-LINE TATTU 4S 850 95c. Thanks.
3.8V to 3.85V per cell. - total voltage of all four cells 15.2 to 15.5V
You also tested 650mAh lipos compared to these? They are about 30gr lighter. Would be interesting if you get more power or same flight time.

@@therccrashproject6330 Thx, I think I will give the 850er a chance.

Also why do most retailers prefer to ship 18650s rather than lipos?

@@7LETITBE7 That all boils down to either the country's regulations or just the pickiness of the retailer.
Good review. Would be better if left hand fingers weren't in veiw. Happy flying. :-)
