@adama12946 жыл бұрын
Here is how you test the amp capacity. It does involve some math. V=IR and we know the voltage and the amps to test at. V = 3.7 I=20 so that gives you 185mOhm so a 200 will test it at 18.5A. The power will be 69W (I^2*R) so a 100W 0.2 Ohm resistor will be fine to test the battery. A battery that has 3AH can do that 18.5A for just over 9 min. So a test for one min with the resistor will not depleate the battery to too low a voltage. Hook one up and measure the temperature of the battery. If it is within operating temps, you have a battery that can do what is says it can.

Thanks Richard. This is interesting. The industry norm has been 18650 for quite some time now. About 4 months ago, Tesla's Gigafactory, produced its first battery cells, in a new format for lithium-ion batteries (21700). I have to wonder if this move will sway much of the market to this size? I find myself now having nearly completly moved on to 26650's. Have you found yourself moving to the bigger 26650's as well?
@richardlloydusa7 жыл бұрын
I buy cells for the devices I own. In the case of the 26650 I only have one device that takes them and that is this flash light kzfaq.info/get/bejne/neCoq6-VqtDRk2Q.html b They have massive storage capability but that comes at the price of size and weight. For lights I find I reach for the smaller lighter 18650 powered devices more often. Thanks.

I had problems with the SKYRC chargemaster software it is buggy to say the least but I did figure out how to make it somewhat stable. After you install it you need to run it as administrator or it will not function well at all. I will be making a video on how to do that and the different versions. I found them here hobbyking.com/en_us/turnigy-accucell-6-50w-6a-balancer-charger-lihv-capable.html with the firmware for mine as well. Here are the files for your charger hobbyking.com/en_us/imax-b6ac-v2-professional-balance-charger-discharger.html go to the files tab about mid way down the page I suspect they are the same programs but they are not clearly labeled so you have to try them all until you find one that works "OK" by OK I mean it only crashes once in a while. Mine crashed when I created a new directory while trying to save the charge graphs. I now use windows file manager to create the directories and then use Chargemaster to save it in the appropriate directory. Thanks for asking as it has given me impetus to create a video on this issue. All the best

@richardlloydusa7 жыл бұрын
You may be right. I own a clone version of the Imax B6 which is why I bought the Turnigy because it is a legitimate charger that I know is genuine. I had people complaining that it was a clone so it was not reliable (BTW it was a good one that is properly calibrated) I may compare the B6 clone with the Turnigy in a future video (of course with the caveat that there is no guarantee that you will get a "good" clone B6). I was lucky to get one. The menus on both my chargers are similar as is the function but the Turnigy has many features that the Imax B6 does not have (like battery resistance) I found it curios that your charger and the Turnigy are using the same firmware revision # Firmware V1.13 this could of course be a coincidence but that is one heck of a coincidence. BTW my Turnigy Accucell 6 is the latest physical version which is much smaller than the original or the Imax B6. Thanks for comments and the feedback. All the best.
@crankshaft0077 жыл бұрын
Richard Lloyd i had a clone b6 just like yours and it had issues with voltage. I sold it and made sure I purchased a true skyrc unit. And was shocked that the real b6 discharge/recharge mah rating being off by 800-1000mah. Then skyrc customer service being basically non existent. When finally posting on Facebook then skyrc telling me that the units are not accurate. ???? Normal for a true Panasonic 18650 cell to be off by 800-1000mah. But measures fine with a opus charger. When I searched online a number of people showed the Turnigy was the same as a b6. With some very minor exterior changes, menu changes. And even as you showed the skyrc charge master program works on the Turnigy??? As well warnings from people to not accidentally update the Turnigy firmware with skyrc firmware. Because options will disappear, just like your resistance option. I will have to check my b6+ because I'm sure it has resistance option and as you said takes that version number. Can't wait for a charger comparison lol. You might even want to get bigclive involved as I'm sure he would love a tear down Cheers

I'm likely only using 3 cells for most but one larger light will probably have 6. I am using 12v LEDs also what would be a good charger for recovered laptop cells. I need one at a good price. I don't want to use a bench power supply. to charge lots of cells. I would like to eventually build basically a power wall type system. great video thanks.
