| DX5R Battery Mod to DX5 Pro
So I had a DX5R that according to the menu should be able to handle 8.4v. My Intention was to grind out some of the plastic in the battery compartment so that i could use a dual 18650 battery sled. cut the plug from the origional 4x AA sled and solder it to new thread and done. 4x rechargable AA batteries came to 4.8v at 2400mAh cuttof voltage is 4.1v though I am not sure on the mAh from 4.8v to 4.1v its probably much less than 2400mAh. 2x rechargable 18650 batteries are 8.4v at 3000mAh with a cutoff voltage of 6.4v. Here the actual usable mAh is very close to 3000mAh and at a higher voltage that may provide longer run times for the transmitter. Unfortunately when I plugged in the 8.4v battery pack the DX5R would vibrate whenever I turned the power off. I found this post on a different web site. Quote:
So I decided to send in My DX5R for this hardware update rayzcar mentioned, brief transcript of email with horizon Quote:
I don't know less then 2 weeks later I get what I think is my DX5R with hardware update back. It turns out the hardware update is replacing the DX5R with a brand new DX5 Pro. The DX5 Pro came with steering wheel adapters of different sizes and angles, and an optional grip as well, no RX. Everything you would expect in a DX5 Pro no RX box to contain. After poking around Spektrum's website I find the DX5R and DX5 Pro use the same 1.04 firmware. All the menus look the exact same to me. So I begin grinding out the battery compartment and plug in my 8.4v dual 18650 battery sled, works great, no vibrating, glad I saved my profiles before sending in my DX5R, they loaded right into the DX5 Pro. Oh and since I didnt send in my old battery tray and battery cover, I have 2 of those now to modify, extra battery plug is handy, and maybe I will use the extra lid to mount the DeWALT battery mod to. | ||

I bought the Spektrum Lipo battery pack, carved out some of the battery compartment area and installed a couple banana jacks and a DPDT switch so I wouldn't have to open the battery door again. Turned out pretty good. I guess I can't pot pics yet. |

I thought about adding a plug, but I wasn't sure if a switch was necessary to protect the radio electronics, and I didn't know how to look that up. Plus I would need a balance wire and that's about how far I got when the little wormy things in my brain threw the overheat protection switch. There is a spektrum lipo pack with a built in charger that you just need to cut a hole in the battery door to charge it. Last edited by Voodoobrew; 12-16-2018 at 10:54 PM. |
