NOTE: This kit is for radios that do not have a charge port on them. If you radio does not have a charge port, then this is a perfect kit for you. If your radio has a charge port and you would like a better charger, please see the Aloft X7S charger.
We love the Q X7 but pulling the batteries out of it every time you need to charge is unnecessarily painful. So, we designed a charge kit for it, that can be installed by anyone who can use a hand drill. The charge jacks are available in either black or white.
The charge kit was designed to work with our 2600mAh X7 NiMh battery and fortuitously it also works with the stock battery clip; you just need to carefully tuck the battery wire and plug into the case, next to the PC board and the stock battery clip will slip right in. The wall charger monitors the battery voltage and stops charging when peak charge is reached. The charger also has a convenient LED indicator light that is red when charging and turns green when charging is completed.
We are now offering the items that comprise the Q X7 charge kit separately. You can buy either the charging harness or the smart charger on their own, or together to make a complete kit.
Should you decide to purchase the charge harness separately and charge with your own smart charger, please be sure that you are familiar with charging NiMH batteries and that your smart charger has a setting specifically for charging NiMH batteries. We recommend you do not exceed a 500mAh charge rate, charging at a higher rate will damage the battery.
Kit Installation Tips:
Study the pictures for reference.
Refer to the pics above and see that the the half inch hole (12mm) is centered in the 45° facet on the right hand side of the rear half of the shell. Accuracy is not super critical here but you need be aware that, if the hole is too close to the back of the transmitter case you will have a difficult time tightening the nut on the charge jack.
Measure carefully and prick punch (make a small divot) the mark so the drill bit does not wander when you begin to drill. Start with a small drill (no bigger than 1/8" (3mm ) and make a pilot hole and then use successively larger bits until your reach 1/2 inch (12mm). This will ensure a cleanly drilled hole and will help you maintain accuracy. A step drill works a treat for this project and is our preferred method.
With the hole drilled, it is time to install the charge jack. You need to remove the hex nut from the charge jack assembly. You will find the nut does not easily slip over the larger white plug. Yes it is tight but it will slip over it with a little effort.
Insert the charge jack into the hole, push the hex nut back over both plugs; thread and tighten the hex nut onto the charge jack. Plug the small white plug with the longer wires into the battery socket on TX board. Thread the shorter wire and plug into the battery compartment, through the rectangular opening in the battery compartment nearest the charge jack. Plug your battery into that wire. Reassemble the case and install your battery and enjoy!

WARNING: This kit should never be used with a Lipo battery pack, NiMH cells only.
