Stan Onymous Posted August 1, 2017 Share Posted August 1, 2017 So if you have a Kingsong 14B you know how fun that little singer sewing machine is to ride. The only problem is carrying aroung 2 extra batteries to go on fun rides. Why didnt Kingsong ever make a decent battery for this travel EUC? Who knows, maybe they wanted to sell you a second EUC for home use. (Greedy bastards) Obviously from a consumer's viewpoint, we just want to ride the heck out of the thing. So while waiting for Jason from ewheels to get some more batteries in stock, I searched the web and found a kingsong 348wh battery for $75 untested, (usually means a fault). The fault with this one turned out to be the red conector had the positive and negative wires switched. So I switched them back to match the connector on the KS14B battery pack. Unfortunately the 348wh was larger than the 14B case would allow for proper closing and attachment. So I measured (once) and marked it up with some whiteout and took out my dremmel to cut out the case. I decided to err on the tight side and cut it out to fit during placement. It is very tricky fitting the larger battery around the attachment screw fittings. Be sure to keep the padding inserts to re-secure the battery inside the case. The next task is connecting the battery wires. i decided to use a crimping connector 10awg for one wire to the battery case, and twisting the other connector together and electric taping and gorilla taping over that for further insulation. I am concerned that this may not be the better than soldering the wires directly to the connectors, but from my solar panel experience, there wasnt any current difference so I decided on twisting and taping along with crimping. Does anyone have any input on this? It will be very easy aside from time, to find the correct solder and get it done if there is any danger. Below are the pictures of the work. I am going to get some shrink wrap tape for the front panel where the battery sticks out to replace the gorilla duct tape. I am shipping it, ground, to the machine which I will test out at the end of August. Let me know about any more mods I should make to this if any.

Hmmh, your photos are unfortunately very blurry and to far away to see what you have "twisted"... But: As there are some serious currents running through the wires i would advise for correct soldering! Really not the place for some twistings. other than that: Great Job! (and good catch:340wh for 75 bucks!!) I can not understand the blame on KS for the batterie options...as i get it this 14b version was always meant to be under 160wh for airplane travel usage. Bigger batteries would not match this and the travel option would be gone?! With the 14c they have bigger batterie options up to 840wh... Also for future batteries: Are you sure that Jason/ewheels is even getting new batteries for the 14b into the shop? i would guess this is a quite outdated product, EUC's meanwhile are forbidden on nearly all carriers, and nowadays a 500Watt wheel like 14b is not anymore state of the art, so i would doubt ewheels.com is getting new material for it.... 1 Quote Link to comment Share on other sites More sharing options...

Bigger batteries would not match this and the travel option would be gone?! I shouldve specified that I tore apart the extra battery pack that I had ordered from eWheels, since it depleted too quickly upon use. I also have a third battery that I bought from Artwheel while waiting. The travel option does and would remain, unless one trades in those batteries. The 348wh battery would make it safer since more batteries are harder to deplete while going full steam up a hill, and lead to fewer sudden shutdowns. I have experienced a sudden shutdown on this machine with the battery at 90% using a 174wh battery, and it was not pleasant. What I was getting at is that if I enjoy it enough to pack it up to travel with me, surely I would be twice as enthusiastic about riding it around while at home, and I am. The travel option is still in place, and hopefully I have enhanced its usefulness while at home. The KS14C is a gem to be sure. Solid and powerful underfoot. I like the quirkiness of the 14B and now will have more use out of it with a simple mod. It only took me a couple of hours. What type of Solder should I use for these connections? The leaded stuff or equivalents? I want it to withstand the shocks. Quote Link to comment Share on other sites More sharing options...
Pedro Posted June 29, 2018 Share Posted June 29, 2018 Hi I thinking in buying the kingsong battery 14b 174wh for my KS-14M: My question is, How many cables are going out from the (original blue wrapper) battery pack? Do you have a cable for common GND, one for charging and other for discharging? Quote Link to comment Share on other sites More sharing options...
