EUC Extreme Posted May 7, 2015 Author Share Posted May 7, 2015 And here are some pics from the project .. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 9, 2015 Author Share Posted May 9, 2015 I opened the Cameron 14" There was Lipo batteries. All looked pretty good. Another battery cable was badly squashed between the covers. But it was in every respect intact. It was through of the motor wiring a large hole that had not been sealed on the water can get in. The circuit board has a button which is capable of running outside. I do not know what will happen to it .. Now should do a few soldering performance improvement... hobby16, could you please advise which parts need to be soldered? Link to comment Share on other sites More sharing options...

hobby16 Posted May 9, 2015 Share Posted May 9, 2015 hi vee, The 3 mosfets are paralleled so they must be shunted as shown by the big red lines. But first, check that they are indeed paralleled : mesure the voltage between the gates and 0V (black wire), you must have the same value (around 10V) gate1=gate2=gate3. BTW, I'm sometimes rarely seen on the forum for lack of time, so wake me up by mailpost when you need. Link to comment Share on other sites More sharing options...
hobby16 Posted May 9, 2015 Share Posted May 9, 2015 BTW, I've successfully shunted the Firewheel260's BMS. I'll post the details of how to do it with very minor cuts in the shrinkwrap. When you know there will be no more battery cutoff, never, Firewheel rocks! Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 9, 2015 Author Share Posted May 9, 2015 All the gates of the voltage 14,97V. Edit: Is it ok? Link to comment Share on other sites More sharing options...
hobby16 Posted May 9, 2015 Share Posted May 9, 2015 All the gates of the voltage 14,97V. Edit: Is it ok? Yes it's ok, go ahead. If in doubt, post a picture after shunting and I'll confirm. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 9, 2015 Author Share Posted May 9, 2015 Done. Even up the battery compartment with a big hole with access to water in. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 9, 2015 Author Share Posted May 9, 2015 Yet I hope that I can have new upgraded circuit board which performance should increase. But seems to be difficult to acquire the silly thing. At least the communication are struggling very hard. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 9, 2015 Author Share Posted May 9, 2015 Thank you very much advice, hobby16 Tomorrow I'm going to open the CXM-character. Let's see what is there. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 10, 2015 Author Share Posted May 10, 2015 Hello, hobby. This would CXM brand battery. Could you make sure what is soldered? Thank you. Link to comment Share on other sites More sharing options...
hobby16 Posted May 10, 2015 Share Posted May 10, 2015 Hi vee, According to your pictures of the Cameron's BMS, your mod is ok. About the CMX : shunt following the red lines. Like before, check first with a voltmeter that the 3 gates have the same voltage. You can also shunt the overcurrent sense resistors (green lines) since they are of no use anymore. This will remove a small voltage drop and add about 1W (power loss = R.I^2) to the available power. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 10, 2015 Author Share Posted May 10, 2015 Again, in mod is now made. Thank you hobby16. Here widgets belonged beeps really quiet. No wonder, because the speaker is in the deepest possible location. I put it in the place to prove straight up out. I drilled a small hole in which the sound is heard as well. New Cameron driving experiences. It would take quite a moderate terrain but the battery is not able to exercise. Although it is full. Voltage drops dramatically and starts to beep. So I could buy a better battery life, and Cameron is clearly outperform. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 11, 2015 Author Share Posted May 11, 2015 Forced coat Gotway. It gets so rough treatment from me. I tried my Gotway 18inch, 17S and 18S Lipo. And guess what happened .... The device does not agree to boot at all. Raising the voltage is not the solution to speed and increasing torque. Sure, good quality lipo is able to keep the voltage high all the time, so it could add at least torque. 18x2.125 rubber is off-road use too low profiled. Kivikko wheel banging the stones and then today I got a rubber eraser. Fortunately, my wife arranged for transport: D I need to make a 16S lipo, try replicates torque. If this happens, I have to subscribe to their own batteries for this use. Link to comment Share on other sites More sharing options...
hobby16 Posted May 11, 2015 Share Posted May 11, 2015 I tried my Gotway 18inch, 17S and 18S Lipo. And guess what happened .... The device does not agree to boot at all. oh, so bad. You mean no light, no beep, no motor energizing, no nothing ? I'll try 17S on my airwheel clone and I'll let you know. BTW, LiPos with high discharge rates (20C or 40C) would definitely help in boosting the wheel's torque. But LiPos are fragile, it's probably a bad idea (quite risky anyway) to use it in off-road conditions. If we learn some guy has burned a forest with a lithium fire somewhere up there in Finland, we know who he is, lol. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 11, 2015 Author Share Posted May 11, 2015 Yep No reaction. Only a small flash LEDs. Lipo is a nasty sensitive to sharp knocks. But I have the thick padding. But I wonder exactly I put or not .. Just be very little used batteries 40C for sale. n.300 € 6X6S. Among them should be done. Link to comment Share on other sites More sharing options...

John Eucist Posted May 18, 2015 Share Posted May 18, 2015 Wow that's a bigger box on top of the Msuper than the Gotway Tibet guys! What do you put in there? Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 18, 2015 Author Share Posted May 18, 2015 It is something self-adhesive foam disc. 20mm thick. Link to comment Share on other sites More sharing options...
Lorents Posted May 18, 2015 Share Posted May 18, 2015 Impressive... Both riding in terrain with a selfie stick and the lipo mods! I can see that spring is coming to Finland too Do you disassemble the lipos and make your own packs or do you use pre-made lipo packs? Link to comment Share on other sites More sharing options...
John Eucist Posted May 18, 2015 Share Posted May 18, 2015 It is something self-adhesive vaaholevyä. 20mm thick. Oh I thought it was a container to put things inside. Looks really big lol. Link to comment Share on other sites More sharing options...
EUC Extreme Posted May 18, 2015 Author Share Posted May 18, 2015 Lipo has been the only experiment. There is no permanent of goal yet been made. It is a must do .. but I expect the first new shells and the new software I get it more speed. But I do Lipot themselves. I am able to buy the best and where can I download the 10 000ah batteries for approximately 20 minutes. 16S 2P. Charging current 2x40A I had to protect the shells well. At high speed roll over easily broke the shells. Link to comment Share on other sites More sharing options...

esaj Posted May 19, 2015 Share Posted May 19, 2015 That's some serious speed on a dirt track! Must be hard on muscles. All those bumps and jumps make me wonder if there's a way to add some sort of suspension to a wheel without it becoming too hard to ride...

EUC Extreme Posted May 19, 2015 Author Share Posted May 19, 2015 You are right. That's a hard workouts.In my own skills at maximum while driving, my condition will last approximately 5 turns.Then there is the forced silence or take a break. But because it is so challenging, it also is fun and interesting.I have a little flexibility pedals. Separated by a 2mm thick rubber, so it helps to drive faster because the foot is not so easy to prevent slippage even in hard vibrations.The problem has been their strength. One Battery backup and all I tried rubbers are worn completely through.I have to come up with some improvement. Link to comment Share on other sites More sharing options...
