Hi, Where can I purchase original 4110's? Are all the ones sold on eBay from China fake?

The problem with this monitor is that it only monitors the entire pack's voltage, so 1 cell can discharge below 3v and it won't set the alarm because the voltage of the good cells compensate The monitor that I suggested monitors each cell's voltage separately, so the moment one of the cells...

Yep, I use 2 of them myself. No problems like the reviewers wrote. Very cheap and very accurate. BTW, where did you get the 10000mah packs?

Just use two of these while discharging. They will monitor your cell voltage, and start beeping if one of the cells goes bellow 3.0v http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=8927&Product_Name=BM-6_Cell_Voltage_Monitor_2-6S_Lipo_%28New_Version%29

My 2 cents. Since you can't agree on a preferable battery configuration, wouldn't it be best to ask HK to sell loose 5Ah cells (preferably with copper tabs for easy soldering) and the small circuit board they use for connecting cells in series/parallel? Then each user can assemble his own pack...

Hi Spanky, You don't have to set the charger voltages. Just input the number of cells in the pack (5S) and the charger will take care of the voltage. You can also set the charging current. It is not recommended to charge over 1C, 5A in your case. You just connect the pack's main wires and the...

Hi Luke, I was thinking of using a servo connector http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=5493 where I need 3 pin connectors and the JST connector http://www.hobbyking.com/hobbycity/store/uh_viewItem.asp?idProduct=5496 for 2 pin. What do you think? is the servo...

Thanks LiveForPhysics, but those connectors are intended for soldering to a PCB, not cable to cable. I dont like the fact that I need to use shrink tubing on each pin and that the body is so tiny that when detaching the connectors you might pull off the wires by mistake. A good connector body...

Where can I buy these? Do you crimp the pins, or solder? Can the pins be easily inserted/removed from the housing?

Hi, A short poll. What type of connectors do you use for connecting wires that do not carry high currents/voltages (i.e control signals)? I currently use the standard connectors that come on the controllers (http://tncscooters.com/product.php?sku=101162), but I am not very happy with this type...

Nope, no problem at all. I built a 8s4p pack using 4s1p 4000mAh packs I ordered from eBay. Just hooked up all 4 balancing taps together.

But will the one from Allelectronics work down to 24v?

Cant find the 24v Vicors on eBay. According to the tests I saw on a different thread, using a AC-DC switching power supply as a DC-DC is much less efficient 79% compared to > 90%. It's amazing how cheap you can get an AC-DC 12v5A P.S on eBay for. I cannot understand how parts+labor+shipping can...

Hi Matt, Check out this thread on the HobbyKing forum: http://www.hobbycity.com/hobbycity/forum/forum_posts.asp?TID=289 by liveforphysics (from our forum as well?) He says that the new generation of Turnigy ESCs are pretty good, and do not loose sync with the motors at any time. These...
