What's your fav feature of this M9 charger? Let me know in the comments and make sure to check out my site at tmacfpv.com/build-your-own-micro-fpv-drone/ for more fun build info and gear recommendations!
if the charging current is a mathematical question according to each type of battery, why isn't the best value automatically indicated? The software should ask how many milliamps the battery has and suggest the ideal charging current according to the type of battery indicated. That would be a user-friendly function
User Manual (linked in this video's description), page 14 describes 3 different Discharge Modes and their max rates/capacities. I tested the "Normal Mode" for you with a 4S 650mah battery LiHV. Normal Mode max rate/capacity per User Manual is 3A @ *20* W discharge. The M8 (on the other hand) in "Normal Discharge Mode" has a max of 3A @ *12* watts. I set final voltage to 3.50V/cell= 14.0v total and set the discharge rate to 2A. Battery starting voltage was 17.2 volts. It discharged fine beginning at approximately 1.17 A (1.17 A x 17.2 v = 20.1 watts). As the voltage dropped, the discharge amp rate went up to *maintain the max 20 watts* . As it neared completion at final voltage, it went into "trickle mode" and dropped the discharge amp rate to a "trickle" so it stopped dead on the final voltage. I have not tested the other two modes. Hope this helps.
@@TMacFPV Ah, that makes sense. Thank you for doing that. I use the discharge mode to measure actual mah as a pack ages, and if the device limits the amps to under 1 amp it can take over 1 hour to complete the discharge cycle.
No thanks don't need a toy charger that will burn up if loaded with a high capacity battery. tool kit chargers will go on the blink,when used at their rated output!

Great video Tmac wow this is a nice charger u can personalise really cool like it thank u .
TOP REVIEW ANYONE CAN FOLLOW EASY INSTRUCTIONS GREAT TIPS 👍
I'd like to know how well it discharges. The M800 can't discharge any faster than 1 amp even if you set it higher. Thanks for the review.

@TommyTester sure thing Tommy!👍You can also keep track of internal resistances. As batt's age, their IR tends to increase
nice review! great option for a compact field charger
nice review TMac, lots of good info ! Where did you find the parallel charging board ? thanx for video !
Sure thing! I apologize, I meant to have the link in the video description. The parallel charging board is here amzn.to/3quhqIE
hi
do you have the htrc ht208 ? to compare them ?
thanks
..gracias
Can it be used as battery checker - without external power supply?
Yes!👍😁
@@TMacFPV cool, i thikn this is the first one that does it looking back to older chargers
@@msadowniczy it's a really nice charger. Pretty much does it all. I like it. My new " Go to!"😁
"Main port disconnected"
Toolkitrc m9 ошибка
Что делать?

I wish someone would make an amber sound packs for this charger... I can't stand the voice they used....
I just turned it off, got annoying reallll quick
