How do you solder the red & black wires to the white plastic plug without melting the plastic?

Yesyns (27%)
I did was soldered the wire first then heat the soldered area with soldering iron. While it still melting (solder flux), join it to the correct pin. Do not hold too long! or the plastic might melt. When you see both wire and the pin bonded, then move away the soldering iron. Wait a few second to cool down the wire bonding. If you still not sure, practice first with other materials.

SeppelS (35%)
You could try to disassemble the pins and solder it then. I'll use a simple "pin-line" instead of the plug. Then you won't have any problems when using batteries with different balancer-plugs.

Cliff (44%)
The pins will push out the back of the plug. Then solder and push back in. I have done it both ways.

place the plastic portion dipped in water only the metal surface should be out enough to solder dinesh

tienes que preestaar los cables primero, y despues con un soldador de poca potencia y un estao fino que funda rapido le aades una pequea cantidad a las patillas del conector, despues juntas las dos partes (cable y conector ) y das un poco de calor y se fundira rapido, quedando cable y conector bien unido, importante que no le des mucho calor y retires rapido el soldador cuando funda el estao.

Hi! I solder only two wires in my esc (black and red).
Is more easy, i think.
Sorry, my english is very bad!

wilson (46%)
Eu soldei os dois fios nos fios do mes esc e tudo funcionou muito bem. Faa isso e no precisar mais mexer nele.

Use a low-temperature soldering iron, or only hold the iron on the pin for a brief second.

Make sure the pin and wire are tinned with solder, hold the wire against the pin, touch the pin with your soldering iron for no more than 1-2 seconds.

That should get the wire soldered on without melting the connector.

USE LITLE SOLDERING WACH FOR THE VIDEO ON YOU TUBE SEARCH FOR SOLDER BATTERY MONITOR .

Antons (74%)
Holding the pin with small pilers, or solder it connected(Caution not to short out lipo!) You definitely can pull the pins out of the plastic part, solder them and push back in.

Plug the loose plug end into an adapter lead (NOT A BATTERY) to keep the pins aligned during the soldering process. Clamp the loose plug end in a pair of hemostats, pliars with a rubber band around handle or a pair of vise grips. Then tin each of the wire leads by touching your solder to the tip of the soldering iron so a little ball of solder forms then put the bare end of the wire lead into the solder and then immediatly shake off the excess. Tin the conector prongs the same way and then hold the wire to the connector prong and aply the soldering iron until the solder on the tinned wire and tinned proing prong flow together. Remove heat immediatly.

no more than 25 W soldering gun, best fit first to the battery pack ( temp absorbing & no pin bends)and be very carefull for short circuit to live battery terminals.

Ceccoz (64%)
You can use a solder gun with lower power or try to solder them very quickly and you Will not have any problem. I've also fixed the pins of the white connector with a drop of ciano to avoid their sliding into the housing.

tim (92%)
generaly you will melt some of the plastic but the partthat melts is not required so dont worry about it

Elli (42%)
Carefully :) 1. Tin the wire, cover it with solder. 2. Add little bit of solder to the connectors quickly before they heat up. 3. Put them near each other and melt Honestly, I was not careful at all when I soldered, and it was not a problem.

DukeZillo (65%)
you can put off the pin from the white plastic plug, and solder. I solder mine with a 25 watt pencil solder with no problems

hrafnkell (37%)
Be quick and keep the temperature of your soldering iron rather low.

Cedric-Be (34%)
It must be soldered very quickly with an iron 25w

J_Munk (30%)
You need to be quick to solder, in order to not melt the plastic.

dkircali (66%)
first get some solder on the wires and when soldering to the plug touch the iron as far as possible from the plastic, if you can't do it in the first attempt let it cool first then try again. Soldering it directly to ESC is an another option

DukeZillo (65%)
i solder with a 25watt pencil solder without problems.

Hermansjoerd (29%)
Use a small soldern iron 25 watt and you do fine :) apply a bit of soldern stuff on the wire and on the white platic plug and then melt them togeher! its easy mate!

kawish (42%)
you can use ISP headers.

Keeevin (39%)
first, if you have a temperature controlled soldering station, set it to about 380 - 400C. yes, that is very hot, but the trick is to apply the heat very quickly, before the plastic has time to melt( try do do it in about 1 second only ! ). now put a bit of tin on the pins you want to solder. apply heat only very shortly.
now, tin your wires with your solder. you may apply a nice thick layer of solder on them. now, put a small shrink-tube over your wire, and place the wire on top of the pin. now you just apply heat ( once again, very fast ) on the pin and wire, until they merge together. check for bad connections ( your wire shouldn't come off with a gentle pull ) and place the shrink-tube. you're done !

balf00r (63%)
Hi, I used a "third hand" small crocodile clip to hold the plug gripping one of the pins, this provides some heatsink, and a fine point soldering bolt. Tin the pin and wire prior to bringing together.

Sebastien (63%)
You can solder pin without plastic case ans insert pin after

mongomongo (34%)
Easy to solder, just use a good hot solder and try to be quick, i had no probs with melting..

Carlo (75%)
Met een fijne soldeerbout lukt het goed. Wat nog beter resulttat geeft is dat je de te solderen fiche in een stekker steekt dan blijven de contacten op zijn plaats zitten.

Carefully

Oracus (69%)
The pins come out fairly easy. remove pin solder, heat shrink, re-install pin

JC (24%)
With a low power iron max 25 W and very quickly. Solder the wire and the plug separatly only then join them and re-solder.

unbeatable for this price !

Cedric-Be (34%)
yes... It's a very good product.

I have been using this batt monitoring devise and found that at full charge light blue, and flashing blue when getting weaker. At 9.7V the blue off and Red light on and one beep alert. Less than 9.7V contonius beeping sound to warn you to land the Heli and batt need recharging. Excellen devise and very helpful....

There is another similar device with 2 buzzers, red and green LED and applicable for 2, 3, and 4 cells. The buzzers are comparatively louder than this one and more importantly, the price is even cheaper. This item seems out-dated already.

coolbudz223 (50%)
which one?

gmmiracle (56%)
can any one tell me how to tell the difernce from a 3c and a 4c or 5c.

nowinkk (82%)
c in this case means cell, number of cells in the lipo pack in series.

coolbudz223 (50%)
3 cell = 11.1 volts 4 cell = 14.8 volts 5 cell = 18.5 volts

cascas (76%)
The diffrence is the voltage that it triggers at. 3c is for 3 cell Lipo batteries, 4c for 4 cell... etc. So 2c= 7.4v, 3c= 11.1v and so on. You need a different trigger voltage for the alarm depending on what voltage batteries you are using.

heey,
does anny ohne have a english review/installation guide on youtube of this product?

no more dead batteries these things work great loud enough to hear the beeping the lights arnt so great but the beep is good i have put one on each plane.cheap as chips considering how much money you will save on batteries.

rene046 (72%)
Super handig.

Werkt perfect, kabels zijn iets stijf maar heb ik ingekort zodat hij kort op de lipo zit.

Leuk voor iets van beveiliging voor kleine beurs.

anthony (30%)
A reviewer said it starts beeping at 9.8v, that seems a bit high seeing as its generally accepted that you can use a lipo down to 3v/cell (thus 9.0v). Can this be adjusted at all, otherwise I imagine that the beeping will get very annoying and you wont know when it gets down to actually 9.0v?

Marek (58%)
Think about it: it should warn you that your battery is critically low, not state the fact it's dead! You still need time to safely land your craft. The voltage cutoff is adequate and you sould fly so as to never hear it beeping.

cascas (76%)
I think it is intended for planes and heli's so you want some time to land safely, if it triggers at too low a voltage you may run out of juice in the air and come crashing down. It may be a small nuisance on land vehicles, but I notice that you don't have much time left when it starts beeping to when you notice a power drop and it's time to swap batteries anyway. It's still better than burning up your r/c and battery(s).

Malfamartin (71%)
There is a way to safely use a LiPo battery in a Tx! Install a 3S Maxpro Battery Monitor, but install it AFTER the main switch. If you install it directly to the balance connector you will have the current draw all the time. It is not reliable enough to just look att the Voltmeter on TX. You might not look at the meter when you really need to.
Check Rhino 2620mAh 3S 11.1v Tx Lipoly Pack and it's Discussion forum for your TX. If you are a real modeller you can drill a hole in the TX so you can see the Flasching LED.

webber (98%)
Can a LED on this device be transformed on a separate wire?
The whole thing looks not "scale like", I was thinking of putting a buzzer inside the aicraft (perhaps, upgrading its volume) and the LED at the bottom of the plane...

Brecht (52%)
It's easy to desolder the Led and replace it with a longer cable.
Good idea by the way.

NICKSS (67%)
please give me the R4 and R5 resistance (at the bottom) values in order to modify them for higher buzzer volume.

holle_1 (65%)
how do i have to connect the cables to the plug?
there are two cables coming from the maxpro-board(one red, one black) and one white plug with 4 pins.

professorfate (78%)
If you put a meter on the JST plug of a 3S with +red to red, the other three wires (various colours) will give you the first cell voltage on the one nearest the red, the first two cells combined on the next one and the total of all three 3cells on the furthest from the red. That's the one you hook up to the black wire. And of course, red to red. If you got it right, it will beep and flash a blue light if your voltage is sufficient. Check the wire order as different makers use other combinations, but this applies to Loong Max, Zippy, HXT, Hobbycity and some others.

Cralis (67%)
So, it's basically trhe 2 outer pins you connect to, assuming red (one one side) is the one that shows the most voltage, and then black, also furtherest out) is ground?

slumberjer (88%)
Please stock this buzzer..immediately..

samol (59%)
Is it possible to adjust the buzzer voltage ?

professorfate (78%)
Is there a 2 cell version coming?

vito357si (93%)
They have a 2cell here is the link ***********hobbycity****/hobbycity/store/uh_viewItem.asp?idProduct=7224&Product_Name=Maxpro_Battery_Monitor_2S

kaon01 (67%)
Supplied connector (white plastic, 4-pin) does not fit Hyperion/Turnigy batteries.
Manual clarifies:
> 11.1V steady blue
11.1 ~ 10.2V flashing blue
10.2 ~ 9.9V steady red
< 9.9V flashing red and beep

kaon01 (67%)
oops, I meant that as a top-level reply.

Silvar (45%)
Steady red is on beginning with slow beeping.
Power consumption 11mA. With beeping ca 20mA
