Tired of AA's... - RC-Monster Forums

So I got a Summit, and I'm pretty much stuck with the TQ4 radio. I'm not spending $400 on a 4PK....

So I was at Linc's and we kinda got on the topic as we were running of these stupid cheap radio's with AA battery power. He said he had a solution for my problem.

Behold the beauty of cell phone. The pack was made from 3 cell phone batteries. These batteries have their own low voltage cutoff built in. They are around 1000mah so they should last a good while on a charge. The pack was made with a regular Rx pack connection. So I simple soldered a female rx connector to the radio's positive and negative's on the battery tray and viola! Worked like a charm.

Thanks linc!

Here's a pic of the battery tray on the TQ4.

And I got them from Sikeston34m a while back. Good setup, I still have 2 for my 2pl futaba radio. Cheap too, think it was 20 bucks or something like that!

It definitely lightened it up as well.

Aaaahem. Did I read my name? LOL

You know something? I've made/sold a number of these setups.

The first two original setups that I made, I still use today! After countless cycles, they will still play all day.

I still have some other sets if yall need more.

I'm glad you like that. I never use AA Batteries anymore.

You didn't set him up with the female charge jack?

Thats ok. I have a Rx charge adaptor for my Hyperion 720i and I don't mind unplugging this. Its works great!

Cool. You're gonna enjoy it. They provide some nice run time too.

What I did on mine, I opened the radio case. Then I drilled a hole to mount a female "M" style charging jack. My Charger has the male plug.

I just plug it up every so often and it stays fresh. Don't even have to open the case anymore. Haven't opened the case in a year and a half now.

I set them up with the male radio style plug, as my 3pm and the other radio I had at the time had a female in the battery tray. Also nice if it goes dead, I can jsut swap a fresh one in, as I had 4, now have 3. I also have 3 of the bigger format cells that you sold me a while back. Need to dig them out and arrage them to fit as well. The futaba is my boat radio, so it is nice to have spares while I am at the pond!

Hey Linccccc

I kind of did the same thing for my MX3 Cell batts are a great idea. I used batteries I got from Snellemin. They are perfect for 3 to fit in the TX case with the tray removed. there is actually a lot of wiggle room even with the balance connector and foam I added to the back. My radio shuts off at 9V and I think these batteries can actually go down to 2.8V They charge as Li-po and are about 1800mah.
Not a very good pic but.
