  • Small and affordable multi-cell battery voltmeter

    posted by pcmihnea on 15:44:31 G8T 18/08/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: It is designed to measure the individual and total voltage of a multi-cell battery pack (that is, the cells are connected in series). It supports up to 6 cells, and displays each's one's voltage with decent accuracy.

    Cons: It appears that my module doesn't measure AA (R06) battery cells (that is, under 1.5V per cell), thus requiring me to connect the test pins at a a pair of cells (so that it will measure up to 3V per cell). Also, the IC's markings are scraped off, leaving little to none post-market mods (both F/W and H/W).

    Other: Very useful for balancing charge of multi-cell battery packs!

    Pros: Nice small tester for my Lipo batteries. Very large numbers. Tester is so small and light that I left it connected in my glider for some flights.

    Cons: You have to be carefull when conneting battery so you don\t change sides. There could be some identifier.

    Other: If you don\t need alarm for your Lipo, than it is good choice for accasional battery check. I need to get one with alarm also...

    posted by bibiricat on 03:46:45 G5T 30/05/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Works great, it's very bright even in bright light. Shows cell voltage first (first cell, second cell, etc.) and total voltage last.

    Cons: It uses battery power, but since is use only for battery check, it's not a big deal. Be careful that it only works with a minimum of 2 cells , and a maximum of 6 cells , but can measure more then 6 cells, just not all at the same time.

    Other: great price. Every one that uses LIPOs need this, since over discharging a LIPO is bad for battery life.

  • handy voltmeter for lipo batteries

    posted by theo44 on 14:36:22 G2T 14/02/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very light and small, good for RC helicopter use. I use it for bicycle lighting system. So I don't drain the battery too much . Beep is very loud so you can hear it in traffic well. simple mounting

    Cons: Beeps evry time when you plug it in . anoying Simple plastic shrink tube around . Plug from battery can be mounted in 2 ways, but only one way works . Difficult to place neatly in a dashboard or to attach to something. uses 20mA when attached too battery . So you have to remove it after use .

    Other: Works great, good price . Excellent for hobby and RC batteries . With some work you can build it in a housing .

    posted by Paladinxxx on 11:14:02 G1T 13/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Not to shabby multi cell voltmeter that's easy to use and very visible even in daylight outside. Very easy to use, and can keep you from flying with a non fully charged battery.

    Cons: Not very accurate on the individual cell readings

    Other: for what it does it does it well... I have 2 of these meters (in case I lose one) and they are one of the most usefull tools in my RC tool box

  • a good voltmeter, no way to change firmware

    posted by mlksa on 14:34:19 G6T 08/06/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: It's a multi-channel very cheap and tiny voltmeter.
    LED display is bright enough, build quality is very good.

    Cons: It is not precise, with pin 2 open it told me there is a 0.05V
    You have to connect pin 3 to + of a battery or a power supply to get device working.
    The most important is that no firmware upgrade available. You can't change the speed of indication per channel, you can't add over- and undervoltage detection.

    Other: It's a great device, however you can't change the firmware yourself.

  • Lipo Volt tester

    posted by avjamash on 00:04:14 G2T 09/02/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Very easy to use, and very handy out on the field especially if using for air or sea vehicles in making the decision to use a battery or not before flying or boating.

    Cons: I find the more cells a battery has the more inaccurate the unit becomes (reading higher than the actual voltage). Cell one's reading being the most accurate (within about 0.03volts) and I was using up to three cells in which the third cell was least accurate (0.06volts deference from actual)

    Other: Very handy, accurate enough to make a educated decision whether or not to bother driving, flying, or boating with your chosen battery. Also handy if you accidental mix charged batteries with used ones. I personally recommend this product.

    posted by iccyy on 18:26:35 G7T 03/07/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: In my previous review, I thought it measured votlage at various pins...
    No! It measures individual voltage of each cell, and the total voltage eventually under ALL.
    Actual measurement against Fluke89-IV:
    No1. 3.47 Actual 3.4775V
    No2. 3.45 Actual 3.4711V
    No3. 3.54 Actual 3.5489V
    No4. 3.57 Actual 3.5629V
    N05. 3.76 Actual 3.7548V
    ALL. 17.8 Actual 17.806V.
    It appears that the maximum error is 0.03/3.50 gives 0.5%. For all intent and purpose, it's amateur grade and fit for use.
    So when charging, should not go for 4.22V full charge, but 4.10V for safety.

    Cons: Well, I would pay more if they provide and under voltage, over charge alarm pin out, to be connected to warning alarm use.

    Other: For $1 to $2 more, it could be built into a professional grade product.

  • Cheap and Dirty Voltmeter for multiple Li-on Pack.

    posted by iccyy on 17:14:29 G7T 03/07/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a cheap and dirty multi-cell voltmeter I would have to build myself..... It scan through all the cells, beginning with No1 . . , till All.
    By the way, pinouts are printed on the PCB, with pin1 marked '-', pin7 mark '+', the rest sensor pins.
    This make a wonderful panel meter ... I 've been looking for my HV modules, one for 0-10, 2nd for 0-3 representing 10mA and 3KV full scale. Wonderful.
    But this one is for multicel lithum pack indicator.

    Cons: What a pity that it did not produce warning and or voltage fault output when one of the cell is under votlage or over-voltage based on multiple of 4.20V.
    Otherwise it will becomes one of those killer applications/prodcuts that every RC or lithium pack needs.

    Other: look like I may have to buy a few!

    posted by ecotack on 06:26:01 G2T 12/02/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Price - cheaper than the cheapest panel meters. Size - Its small, but not microscopic Usefulness - It make a job that would normally be difficult with a multimeter very simple Build - OK, so its not in a box, but the soldering is spot on. Idea of using clear heat shrink is brilliant for this device.

    Cons: Can't think of a single one (must be a first)

    Other: If you have any battery packs with the balance charge connector, then buy one of these now, go on, what are you waiting for?
