Battery Voltage Checker - REVEIWED! *** PICTURES *** UPDATED 5/31

Edit of 5/31 is in BOLD

My third review! This one is on the Battery Voltage Checker, from HeliPal.com

Packaging
Once again, great packaging. Little to no movement inside the box, even when shook.

Comparism
Good little device compared to the large voltmeter.. Although it is a bit inaccurate, it gives a nice "around voltage".

Installation
Easy. Plug your balance connector (Black on the bottom) to the 1-3 pins, and wait a couple seconds, and then you know your voltage!

Features
This little bugger is the length of two quarters, about the width of 2/3 of a quarter. It has a tiny microprocessor, it can also handle up to 6 cells! You CAN plug this in, and test underload.Plus, it's VERY bright
Overview
Definitely a neat little thing, with the amount of technology we have going around, I wasn't very surprised to find this on the market. Sure it has some inaccurate mistakes, but it is sure as hell nice to have around the field, or maybe even the house.

Recommended?
If you don't have the sharp prongs, for your voltmeter, and don't feel like blowing 5 bucks, you can blow off 20 bucks, have a smaller device, and know your voltage. Plus, you can use it for the field, and don't have to worry about shorting your battery out. So, YES, I recommend this product. (To those who don't have a high-tech voltage checker multimeter. :])

Worth The Price?
$20 is a little steep, but, it is very nice, and okay for the price. Not completely great, but good.

NOTICE:
I AM USING A CHEAPO CHARGER, SO IT IS NOT BALANCED, NOT THE DEVICES FAULT. PLEASE NOTE

Does it come with the plug?

How do you know which numbers to plug too?

Does it come with a case?

Oh and thanks.

Looks great!

Can I use it to measure voltage under load? I mean, what about using this nice voltmeter to monitor individual cell voltage in order to avoid overdischarge? what about plug in while heli is flying?

Yeah, that's it.

The plug? You mean the gold pins? Yup!
It has 1 2 3 4 5 6 labeled underneath the heatshrink, which is real visible
No, unfortunately not, you could store it in a little medicine tube thing. It has clear heatshrink, which is nice.

YES! Just tape it up, plug it in, and BAM! Just make sure it gets somewhere visible. This thing is BRIGHT ALSO!

I have the same gadget which I picked up from an e-bay trader for less than $5. It works good, but there is no way of stopping the auto scroll between all of the cells, so you have to wait for it to scroll through 6 cells before you get to see the first one again.

I have used it to check the cells under load - plug it in while the pack is mounted to your heli, then whilst firmly holding on to your heli (ensure you keep the blades away from your face or anything else they could damage) add some throttle and watch the voltage.

Like I said, you will have to wait for it to scroll through each cell, but it works well. If you could stop/control the auto scroll, it would be even better.

Cross checking the voltage displayed on the gadget with my multimeter, I found it to be reasonably accurate.

Cheers

One more question.

Can I use this tester with lipo packs that do not have a balancer plug? My 1 cell packs only have positive/negative plug.

thanks.

rawfuls,

but, have you tried to do it? I think it should be possible right? I see no reason why not, but Im not expert.

Thanks

You CAN plug in the JST, but make sure to have it make contact. I've gotten it to run about 3 times... I guess it isn't the best, but it would work

Bambino:
No, never personally tried it. It IS possible, but I've never done it. My dad is a electronic engineer, and he said it definitely possible, he said he worked with these back when he was working with the batteries to power up the airplanes GPS, and small electronics.

REVISION:
YES YOU CAN DO IT UNDER LOAD
I FORGOT ABOUT HOW THIS WORKS ONLY FOR THE BAlance tap

SORRY!

Well, we'll see how much my paypal has.

Oh yeah, $3.00.. Looks like it's off to the working time! I gotta save up for summer.

This is the link that HeliRyan gave when he posted about the voltage read out device in another thread -

http://www.rc711.com/shop/product_in...roducts_id=683

He says its bright, sometimes attaches it to the battery and hangs it off the balance plug whilst flying.

Good review rawfuls.
Looks like I have the same multimeter as you do from sears. Nice unit.

Sirion,
I use the Common Sense RC version called Cell Spy lipo voltage tester
that reads 3 cells.
It is very bright.
I just attach it to the balance connector and tape it to the helicopter
anywhere I like.
The tech guy at CommonSense RC told me it is fine to attach the unit
to the helicopter and fly it that way. True voltage readout under a load.
Also some guy he knows does it.
He said you can also attach the unit and check the voltage under a load
on the ground. Use caution not to get hit with the blades!
I'm not sure how much throttle to check it at.

Tom

Tom - thanks for the link, has a good vid demo & the guy's a bit of a comedian. Good stuff. Could easily use one to check the activation voltage of a regular LiPo alarm.

SORRY.
I TOTALLY forgot that it plugs into the balance. You CAN plug it into the helicopter, and watch under load. I am VERY Sorry. I must've been wacked out.
