Thank you all for the replies. I am curious about the Molykote because the grease did not feel like silicone grease at all when we handled it. Jerry what are the differences (if any) compared to before when you use ordinary grease? Does the gear slip more or not? What about efficiency and noise? But the point is moot because I just have to use the same RedNTacky grease that the monstertruck The Equalizer uses. I am totally taken in by that testimonial. Or not. But the product might be just the thing even so.

I and a mechanically inclined buddy have been taking my 120SWX24 Tongxin 180W 190 r/m motor apart because of very strange noises and at the end a total inability to turn on power. It turned out that the inner bearing inside the rotor has excessive sideways play and one of the permanent magnets had been grinding on the stator. Bummer. In the end the magnet slipped from the glue on the rotor and got half stuck. Well, a new bearing has been ordered (it is a 626ZZ btw) and when we put the motor back together I need to grease it. But which grease is the proper type? Bearing the planet gear design in mind I would imagine that any old grease would not suffice? Best RocketDane

Well, the cells seem all right. Here are values from measurements under load: Cell 5A load 10A load 1 3.85V 3.71V 2 3.85V 3.68V 3 3.80V 3.71V 4 3.85V 3.68V 5 3.87V 3.70V 6 3.86V 3.80V 7 3.86V 3.69V Which leads to the conclusion that the BMS is likely at fault for not letting all this lovely electric energy flow to the motor. But how to fix it? Best RocketDane

Thank you for the quick reply. If there is a bad cell it seems a bit odd that we got 5-10 A out of the battery with a constant voltage of 28 V. But you are right we did not measure the individual currents while under load. Will do. Can you elaborate on your comment "standard 7-cell BMS"? Is there documentation for this somewhere? Cheers.

Hi all The electronics in my battery do not work properly and I am looking for a circuit diagram or any other info on the battery. It is a Protanium BP-L2410SH1 29,4V DC 10Ah and the board has this text on it: 7SGHP-VERD-20070928 Without a load there is full voltage on the output but when a load is connected the voltage drops to zero. Measurements inside show that the electronics charge the cells and distribute the voltage nicely between the cells and they can be discharged with a good current by wires connected to the inside. But the fets do not open for the full current when I try to discharge it normally. Apparently the fets are not instructed to open but finding out why could be a real pain so any help will be very much appreciated. This is what the board looks like if anybody recognizes it? We have tried shorting where it says "reset" but to no avail. Thanks RocketDane
