I've posted about this in the main Crafty thread at some point as well, but the crimp pins used are the Hirose DF3-22SC, and the plastic housing for the pins is a DF3-2S-2C. You'll also require a crimp tool w/ a maximum 1.9mm crimp size (@ 1.9 you'll need to tighten it slightly cross-ways after crimping, or it won't fit in the housing, but a 1.6mm crimp is a little tight and can be tough to remove from the crimp tool after crimping)Did you manage to find out what is the connector type for mighty/crafty battery for the device mainboard? I need to change my batteries because they currently have about shortened cycle time and i need to cherge it 2-3 times a day. I live in Europe so i guess buying 2 packs from you would be both costly and i would have to wait for delibery and customs. I decided to try making it on my own. Can anyone tell me what is the connector type for the might battery? if i damaged mine id like to have a spare one
You can get a crimp tool for these if you don't have one from Amazon for about $50-$80 + shipping.
what do you mean by “normal df3-2s-2c connector?” (I didn’t know there was more than one type of df3-2s-2c ...)@JCat Thanks for reply.
How about normal Hirose DF3-2S-2C connector? Wont that work?
About the cable do you think 24 AWG will be enough?
Fine threaded like locomotion cable? Usually the awg is what it is, unless aluminum compacted?what do you mean by “normal df3-2s-2c connector?” (I didn’t know there was more than one type of df3-2s-2c ...)
24awg is not sufficient for the current in these devices. You would need a minimum of 22awg and I use a specific 20awg that has a smaller than typical actual diameter so that it is compatible with these connectors.
It's very tightly wound, so thus the diameter is slightly smaller than other wound 20awg wire I tested (It's a silver plated wire with a high temp and durable shielding)Fine threaded like locomotion cable? Usually the awg is what it is, unless aluminum compacted?
Although I mentioned that there might be an issue w/ the 24awg wires, now that I think about it, this is not necessarily true; as the heater in the Mighty may run at a higher voltage (since it has 2 cells) vs the Crafty, depending if they are in parallel or series, and if they are running at twice the voltage than that would half the current requirements to generate the same power.Hey, got to install new batteries to my mighty today.
And these connectors:

Hey there!
Planning on changing the battery on my crafty, been searching but haven’t found anything concrete among the 400 pages and was hoping to get some help from all of you smart folks regarding the choice of battery.
Planning on using Sanyo NCR18650GA 3500mAh - 10A (3.7V Lithium Cell 18650) - Witch as far as to my knowledge should work flawlessly, am I right in my research? Only thing I could think of that could be an issue is the charging current.. but shouldn’t be an issue right?
Ps also planning on changing the battery on my mighty
Cheers
Thanks I read the thread before posting, but since he only installed an 18650PF and not the GE with 3500mah I wanted to check with you smart folks before pulling the trigger since the 18650ge the crafty+ came with as stock was only 3300mah
