I ordered this for a thunderpower 4cell....But I'm not sure how to connect it. the thunderpower 4cell batteries have 6 pins not five.... i also ordered a jst-hx to thunderpower 4 cell adapter harness to make this work but again the 4 cell thunderpower plug has 6 pins and even the adapter harness only has 5 pins....Uuuuuhhh what do i do??? please help before i order ANOTHER wrong adapter... Thanx.
You can connect this to other packs, just keep on mind that you always have connected red with red, and black with black wire no matter how much pins are on the connector.Also you can buy some additional balancing plans which will have enough pins for your battery pack, since this monitor comes with unsoldered wires it only makes your job easier *)
According to manual 14.8-13.6V blue light flashes, 13.6-13.2V red light shines, below 13.2V red light flash and beep. If under load, voltage stays under 13.2V for 5seconds, red light and beeper won't stop until monitor is disconected.
If you have 2 of the same spec battery then you should have 2 JST connector from your batteries. Therefore you will have to purchase QTY-2. Granted that these battery would drain at the sametime. But what ever.. If one happens to buzzer first, you should still bring down you Jet/plane/Heli..
The big trick is learning how to "tin" the pin ends, I usually put a little "flux" on the items i wish to solder, then i pick up some solder on the tip of a soldering pen and quickly brush the flux with the tip of the soldering iron. With that done, place the wire on the tinned pin, and touch the wire with the soldering iron until the solder flows 1/2 sec- 1 sec. let cool and do the next one. hope that helps
Make sure that the 3 center pins are either individually insulated with heat shrink to prevent any possibility of shorting out or simply remove the 3 center pins as they are not required to run this device anyways.As an extra precaution,you might want to add heat shrink to the hole connector and back behind by about an inch as well.This gives you something to hold onto when plugging and unplugging and prevents you from accidentally tugging on the rather fragile wires and their soldering joints.I've done this with all of my lipo alarms and it works like a treat.
I wish they would post the manual, but it looks like it's designed to monitor just one of the cells for a 3v cutoff, and just assume the other cells are the same. if that's the case, you could wire it up with 12 (.7v) diodes in series to let you know when your 12v battery drops below 11.4V.
Can someone confirm the wiring? Do they say to solder to the outermost pins, or two adjacent pins?
This device is just to give the user a visual warning of the total pack voltage whether it's 2S or more. The way this works is that it counts the total pack voltage and works on that. (SO yes, you solder at the outermost pins for wiring). Now, if you have a 2S pack - then it starts giving out warnings when the pack reaches 6.6V (blue light blinking), and so on. If your pack reaches 6V - it starts blinking red and gives out an audible warning tone. I may not be accurate on my warning description but you get the point.
So to be safe, when it starts blinking blue - then you know you're close to your LV threshold - time to bring her in.
If you want something better, then get a Low Voltage (LV) cutoff device like Novak Smart Stop - although it still has it's issues.
Works well. Nice to know when your battery is running low. This is a very cheap insurance to protect your large investment into the plane and batteries. Keep you, your plane and spectators safe. You do need to solder your own connectors it comes as you see in the picture with no manual.
