Volt Meters

[jacobmckeone]

I'm looking to put this Voltmeter in a new mod I'm designing.

DROK Two-wires Digital Voltage Panel Meter Motorcycles Volt Guage 5V/12V 2.50-32V Red LED Voltmeter Battery Tester - Amazon.com

I plan on using this battery
ZIPPY Flightmax 5800mah 1S2P 60C Hardcase Car Lipoly (USA Warehouse)

Or another one like it, and I will be using this charger.

Amazon.com: 5V Mini USB 1A Lithium Battery Charging Board Charger Module: Car Electronics




First Question:

With the volt meter, will the display ALWAYS be on? I don't plan on using it a lot and just want the meter to tell me when to charge my battery.

Second Question:

Will that charger there safely charge a LiPo battery?

Third Question:

Are there any cheaper/more available high Ah LiPo batteries around?



Thank you all so much, it will be my first mod I document on ECF when I'm ready to start.

With the volt meter use a on off on slide switch, that way it can read battery v or load volt, and center position is off. I used the v meter you show many times but now use this as it is much smaller.

Here are the two sizes side by side.

Oh, sweet. Thanks! I just bought a red one, even though I don't know what to use it for - yet.

So you're saying to add a second switch to my mod for the volt meter? I'd like it to just display while it's firing if that's at all possible..

First I would have to know what you what to read, battery V or Voltage at the atty? Is it a regulated mod? With the switch you get both. Even a meter that lights just when firing gets bothersome, it is pretty bright at night. Just wire the meter wires in line with the 510 connecter after the fire button and it will light and read when fired.

I'm just looking to read voltage on the battery, so a switch to flip on and off would be cool. I'll probably just wire it in-line with my 510 because it'd be cool to know the load voltage.
