Tutorial to replace the stock rechargeable battery with 6 x AA batteries. Takes about 30 minutes to complete the project.
6 AA Battery Holder 9V output (2 for $6.99): https://tinyurl.com/y5vyodad
I have owned 3 Maisto Rock Crawler 3XL with the Lithium Ion battery pack and each one had the battery fail quickly. I was able to return the first one ($60, new), but kept two due to getting them at a good price ($8 each, new). I initially searched for new Li-On battery replacements but they were difficult to locate. I found several videos that performed battery mods which gave me the idea to create my own mod. I was not interested in purchasing expensive stronger battery packs and different battery chargers. I also did not want to have to solder since I do not have a soldering gun.
At time of video upload, I have modded both of my 3XL and have been running them just fine for 3 weeks. I’ve gone through 3 sets of 6 x AA batteries with no issues. I would estimate run time of the 6 x AA batteries to be maybe 1 to 1-1/2 hours of continuous playtime (my son and I usually in 15-20 minute bursts over multiple days; I remove the batteries after playing and re-insert before).
Thanks for watching, comment if you have a question. Good luck with your mod!
