Costumer Reviews

I bought this battery to perform some experiments with escalating my flying time. This worked awesome. I now typical about 15-16 minutes flying time, and that is just until is begins to get a small weak. I could without difficulty go yet another couple of minutes, but I do not want to push the batteries that tough, and it's a lot significantly more fun flying with charged batteries.

This modification is protected and straightforward. This is for the reason that these cells use safety circuits to limit over discharge and more than charge. There are a handful of precautions even though:

1. Use two batteries of equal age. This means a new battery in a new heli and a new replacement battery, or two new replacement batteries. Do not mix a new replacement battery with an old, worn out battery.

two. Use two batteries of equal charge - preferably discharged. This is not important, but it is improved to start off with two discharged batteries so they don't have any important energy if you accidentally short some thing. Also, it just keeps every little thing in better balance from the commence.

3. Hook up the batteries in parallel - red to red and black to black. This doubles the battery capacity and increases the flying time. If you hook them up in series (end to end), you will double the voltage, which will burn out the motors if it does not fry the heli's circuit board (and you won't be able to charge them anyway).

This is how you make the modification. Initially, the new battery is in all probability fully discharged, so fly your heli until the battery is discharged (unless you are using two new cells). Then splice the new battery in parallel with the battery in the heli. I identified it easiest to just cut out the existing battery, leaving about equal lengths of red and black wire. Then I trimmed the wires on the new battery to the exact same length. I then stripped and tinned all the wire ends. I then soldered the two batteries together, red to red and black to black. Working with the double sided tape that held in the old battery, I stuck them together. I then slid some heat shrink more than the wires coming from the heli. I then lap soldered the battery wires to the heli wires, red to red and black to black. I then slid up the heat shrink over the solder joint and shrunk it. You could also wrap the wires together and cover them with tape, but that is most likely harder in the limited space, and they won't hold as nicely as solder. Then I removed the weight taped in the nose of the canopy. Finally, you just find the battery more than the battery holder (see photo) and slide on the canopy - it is a snug fit, so there is no need to have to tape down the battery.

With this effortless modification, you will double your flying time - or a great deal more. Every single battery has half the present being drawn from it, so they preserve a higher voltage for a longer time. It really is like the very first minute or two with a single battery, but for ten-12 minutes. Based on how challenging you fly, even right after 14-15 minutes, you can still fly up to the ceiling. Following about 15-16 minutes, I start to notice that the heli is losing trim and it is tougher to preserve lift. I could very easily preserve going another couple of minutes, even flying in ground effect, but why push the batteries that hard. The down side is that it would probably take three hours to recharge applying the USB cable charger. So instead, I'm applying the wall plug charger that takes about 1.five hours or much less to completely charge the battery. The heli is also a small nose heavy, but I like that, and numerous consumers add nose weights anyway. With the heavy nose, you usually have forward momentum, and I assume it really is less difficult to manage. You can also go actually quick in the forward path, but quite slow backwards and you can't honestly hover. You can also add counter weights to the tail (like the weight from the nose) if you do not like it.

Some other notes on battery life:

1. I estimate that the heli draws about 1.2A to maintain altitude.

two. Complete throttle draws about 1.5A max with a fully charged battery, but normally about 1.35-1.4A.

3. Operating the tail motor draws a different .two-.25A.

four. The LED only draws about 12mA, or only 1% of your average present.

So you see, if you just preserve altitude, drift forward, and only turn proper and left, you only draw abut 1.2A. But if you are continually zipping up and down and forward and backward, you are drawing about 1.65A. I am possibly somewhere in the middle and I get a really good 15-16 minutes. Your outcomes may vary.

This was a replacement battery for a Syma 107 that had more than 100 flights. Hope

the new a single lasts as long. Essential factor, with these batteries let them cool just before

and just after charging.
