Remember that this board is really only good for 1S as it is monitoring only one voltage and relies on all cells being the same voltage, whichb as we all know doesnt happen with Lipo's hence the need to balance charge. I prefer the cheap BM6 which does 2S to 6S. Much better.

I have a problem with mine. It starts flashing blue when the voltage has only dropped to 7.8v. I checked the voltage on two different voltage meters. It should start flashing blue when the voltage has dropped to 7.4v. I didn't get mine from Hobby King. As they're fairly cheap I've ordered another. Hopefully it's just faulty.

is this water resistent or waterproof because i plan to use it on an e-revo?
  Reply:  stgram12 (2 points);
of course not! cant you see the soldering? One drop and shortage-fried board.
Better put it in some kind of box or use see-through tape.
  Reply:  dennis (7 points);
Looks like you could use some RTV to make it water resistant, but the speaker would prevent it being waterproof.
  Reply:  Ben (1 points);
Just cover the board in silicone caulk and call it good. A little water will not hurt the speaker. Or buy 2 at this price just to be safe. Hell its cheaper then the shipping.

the speaker is a peizo electric (all metal)so would work under wtaer.

Can someone measure the circuit board dimensions?
  Reply:  BobDeere (0 points);
This works real well for me. But I was wondering if I can get replacement connectors for the alarm?
  Reply:  Kapitan-Panika (31 points);
Without buzzer it have 16x27x2. With buzzer - 16x32x11.
All dimensions are in mm.

Can this be rigged to be used as a plane finder?? I need an alarm that I can hook up to the Rx and switch it on if the plane is lost.
  Reply:  Beaufighter (755 points);
With its own 1S battery or something other below 5V, and a "turnigy receiver controlled switch" I guess it will work. (remember that the "rx controlled switch" need common ground from its supply and the controlled circuit)
  Reply:  Blade Boy (28 points);
Hey Tom why don't you go to a dallar shop and buy a personal alarm. The type that can be used in a door. You can rig it with a servo to turn it on and they are loud as heck.

YOU NEED
1 x Gun (for good looks and to fool step 2.
1 x Golden retriever
1 x Plane painted like a duck.

Hope this helps....

Welcome has a question if the shipment went to the Polish
Thomson (4 points) 5/24/2009
Huh, a little bit stupid question :

Voltage drops below 6V ???
At 3.2V, lipos are nearly dead.
If a lipo is at 6V, your lipo is dead, no ???
  Reply:  stereosonics (15 points);
Have a look here:
***********maxprotechnic****/Maxpro/Technic/MaxproBM.html

It tells you the alarm levels. The buzzer and red LED indicate when battery is below 6.6v.

Cuando empieza a sonar la sirena de aviso de bateráia baja,¿a qué voltage lo hace?¿No llega un poco tarde el aviso como para avisarte de que la vida de labatería peligra?
Gracias

i wish they make 1S edition, too

That plug shown in the picture doesnt look compatable to anything on my car. Do you wire it directly to the leads on the battery or to the balance plug.
