Rechargeable battery mod for Flysky i6 transmitter

thingiverse

The FlySky I6 Transmitter is a Great Device, but It Relies on Outdated AA Batteries. The Constant Need for New Batteries Every Few Days Was Unacceptable, So I Decided to Create a Battery Mod to Make My Life Easier. (In Reality, I Just Modified the Design by Benbojangles.) I've Included Different Sizes of the Battery Cover Versions to Accommodate Various Battery Needs, but Keep in Mind That the FlySky Transmitter Only Accepts 4 V - 6.5 V, So If You Want to Use Lithium Batteries, You'll Need a Voltage Regulator. If You Want to Replicate This Mod Using the Voltmeter from the Pictures, You Will Need the Printed Part "FlySky_Battery_Mod_10mm_with_Voltmeter.stl" and a Few Additional Items. (Note That Only This Part is Optimized for Samsung Batteries.) 1 - 2 Samsung Galaxy Batteries Fit Perfectly in This Design. I Purchased a 5-Pack from an Auction on eBay: http://www.ebay.com/itm/262799324825?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT A Step-Up Converter Module is Also Required: https://www.banggood.com/DC-Boost-Converter-2A-Power-Supply-Module-2V-24V-To-5V-28V-Adjustable-Regulator-Board-p-1100757.html?p=C8021898693762017049 You'll Also Need a Small Voltmeter: https://www.banggood.com/0_28-Inch-2_5V-30V-Mini-Digital-Voltmeter-p-974258.html?p=C8021898693762017049 A Mini Lithium Charger is Also Necessary: https://www.banggood.com/Mini-1A-Lithium-Battery-Charging-Board-Charger-Module-USB-Interface-p-89732.html?p=C8021898693762017049 Finally, a Small Switch Is Required: https://www.banggood.com/20Pcs-SS12D00G3-2-Position-SPDT-1P2T-3-Pin-PCB-Panel-Mini-Vertical-Slide-Switch-p-1000847.html?p=C8021898693762017049 Connecting Everything Together Is Relatively Simple, but If You Have Any Questions, Don't Hesitate to Ask. To Assemble the Mod, Simply Connect the Lithium Battery with the Step-Up Module and the Charger. Place the Switch Between the Voltmeter so That It Can Be Easily Turned Off. Finally, Connect the Output of the Step-Up Module (Set to 6 V - 6.5 V) to the AA Battery Connections on Your FlySky Transmitter.
