How To Modify Your RC Transmitter For LiPo

Article by Hunter Wick

Tired of driving miles to your favorite bashing place or track, only to find that your transmitter battery is dead? Nitro, electric, or gas, all of them require a transmitter, and every transmitter has to have a battery. This article will give you a step by step guide on how to easily modify your existing transmitter to use a LiPo battery. Please note that I performed this modification on my FSGT3B 2.4ghz transmitter, so certain steps may vary slightly depending on the brand of your transmitter.

Before we get into the actual process, you may be wondering why you should even do this, if it will damage your transmitter, how difficult this modification is, and what supplies are needed. First off, there are a couple benefits that come from doing this. Your transmitter will become lighter in most cases since LiPos are lighter than eight AA batteries (some transmitters use four), which will make it more comfortable to hold for extended periods of time. In addition, the battery will last much longer, yielding longer periods in-between charges. Another benefit to this mod is that you will be able to recharge the LiPo, so purchasing those costly AA packs will be a thing of the past. To charge it, you would simply remove it from the transmitter by unplugging the battery using the connectors you will be soldering on. As long as you do your homework before deciding how you want to go about performing this mod, there is virtually no chance that it will damage your transmitter.

For transmitters that require eight AA batteries, a three cells (3s) LiPo is needed. For a transmitter that requires only four AAs, a two cells (2s) LiPo is to be used along with a BEC, so that the voltage is cut to six volts. The four AA mod is slightly more complicated than what this article will focus on, we will discuss that mod in an upcoming article.

Here is what you need to do this mod: about an hour of time, a soldering iron with quality solder, and the connectors of your choice (I used Losi Micro connectors, but there are many other options).

Step By Step:

1. Prepare your transmitter for a "heart transplant", as it could be referred to. To do this, remove all of the AA batteries and remove the battery cover.

2. Take out the battery tray which holds the AAs. In order to be able to do this, you may have to partially take apart the bottom of the transmitter, so that the tray can slide out. The tray will no longer be needed, so it can be discarded if you don't want it. Then cut the wires attached to it, as close to the tray as possible, to give yourself maximum wire length to attach to your LiPo. Be extra careful because these are what transfers the power to the actual internals of the transmitter.

3. With the tray removed, solder on the plugs to the transmitter's wires that match the ones on your battery.

4. Lastly, stuff the new battery into the space where the tray for the AAs once went, but make sure everything is nice and tidy, because you definitely don't want to pinch any wires.

Hopefully you now have a good understanding on how to mod your transmitter for LiPo use. It's not that difficult, and it can bring you several benefits. Plus, it will save you money! I purchased my transmitter's LiPo off eBay for around $10 shipped, versus spending $100s over the lifetime of your transmitter when buying AAs. Now it's time for you to make the switch to LiPo for your transmitter!
