I choose a battery easy to find in Europe:
Gaoneng LIHV 7,6v 450mAh 2s 80C-160C with XT30 connector.
Omschrijving:
Batterijparameter: 7.6V 450Mah 80C 2S
Capaciteit: 450mAh
Afmeting: 14 * 18 * 62 mm
Stekker: XT30 Stekker
Doorlopende ontlading: 80C
Gewicht: ongeveer 28 g
Kleuren: Standaard Kleuren
Voorzichtigheid:
Niet overbeladen of overladen batterijen.
Zet het niet naast de hoge temperatuur conditie.
Gooi het niet in vuur.
Gooi het niet in water.
Pakket inbegrepen:
1 x 7.6 V 450 mAh 80C 2S Lipo-batterij
I made a parallel with 2 of them, and reached 900mAh in total.
If you have an old battery, with a working charger board inside of it , all you need to do is swap the old battery with the new pack.
No need to keep the XT30 connector, you may just cut the power wires just behind the plug, peel them off and apply a good ammount of solder.
You can also remove the balance connector and only keep the middle wire (for each battery) in order to solder it in the rear of the protection board.
Some notes about charging:
- the overall voltage will rise and stop when the pack reaches 8,6V, with little heat (it's an intellingent charger, we wanna keep the thermal probe in the right place, in contact with the cells).
- when the battery is fully charged the number of leds indicating the charge status will be 1 or 2. This will not affect the correct operation during take-off and flight.
It's advised to use the modified version of Freeflight in order to activate the safety functions (RTH and Autoland) in relation to the actual battery voltage expressed in mV.
As said before, the drone will be very precise and reactive in sport mode. It could reach higher speeds and higher ascent rates (software limited).
With this mod it is for me the perfect flying camera for video inspections in urban european areas, because of the zenith orientation capability and of course it's astounding silent performance during hovering.
