Ok I have to say this. I watch almost every rc channel on youtube, I enjoy most of them. Joshua for tuning ,blackbox ,tests, Stew for reviews ,painless,Bruce etch. But seriously man every bloody time I encounter a practical issue, which is imo the most important and time consuming aspect of our hobby, I come to JC. You have everything covered! Ah I got a new fc, damn its not binding to the tx, check JC, problem solved. Oh I broke my vtx, hmm can I save it? Check JC, there it is, done, lets go fly! Keep it up man, your contribution to the hobby is invaluable.
Bro respects to ya, you’re a smart guy and I appreciate the knowledge base you’ve shared. My lipo went low and I only had basic chargers, I upgraded and will use the tips you’ve shared. Peace and God bless
Thank you. Very detailed but easy to understand. Now time to check if I correctly storage charged my lipo...I've got the same charger you have. BTW, those bags you mentioned have been shown to be ineffective. There are videos where people purposely short circuit their lipos and test various safety options, one of them those bags and different kinds of those bags. Almost every one of them fails to contain the fire. I believe one of them sort of contained it, but not effectively. Pretty much the only safe option is metal ammo boxes with holes drilled into them and the seal removed.
Yes, great job explaining! I have forever been afraid of LiPo's mainly because I have heard and seen the explosions on video, and just didn't understand enough to even mess with them. I feel with this and other instructional videos that I now have a decent understanding of LiPos, and can at least now decide if I think they are worth it for me. 👍
Good information JC. I spend as much time with my batteries before and after flying as I do with my quads. Also, if you fly your battery down very low, the voltage drops rapidly, making it easier to over discharge...
I don’t know if this was already said or not but, I have the 1 mini hitch charger of the same one you was holding , can I charge a 2s lipo for my fat shark just with the balance lead ?
No guys, I'm not wearing black nail polish. I hydrodipped the Turnigy Evolution and a bunch of other stuff. Video is on my other channel - ruclips.net/video/BUQmcBEVyzg/видео.html
Hey JC. Are you talking about a 0.2 difference per cell or per battery? Would you recommend the Tattu Li-Pos? I have purchased 2 1300mAh 4s 75C ones. Thanks in advance :)
Any suggestions on what to do if the plastic is torn on your batts, or can we just electrical tape? I know on my vape batteries I use some battery wraps do they make something like this for lipos or should I just use some big heat shrink?
I just use PE heatshrink. The plastic heatshrink tears so easy I just go ahead and put the PE stuff on as soon as I get new batteries. Its has a rubber texture, and a lot thicket than what comes on them. I use 40mm for 1300 batteries. www.readymaderc.com/store/index.php?main_page=product_info&cPath=53_583_597&products_id=6365
Did you really meant 0.2V difference per cell between batteries for a parallel charger ? Or 0.2V of the total voltage of the battery ? Because 0.8V in total for a 4S seems a lot to me...doesn't it ?
For those with an Imax B6 charger: (clone or legit) If you plan to charge/balance/storage at 1C, increase the timer setting which is 200 minutes by default, because the storage charging takes a very long time. (even more for the NiCd trick)
Yo JC, couple of my lipos in storage have uneven voltages , for example my 4s lipo in storage has (3.84, 3.79, 3.83, 3.75). Should I be worried or is that usually how it should be?
You are only a 10th (.1) off on each cell so it is still perfectly usable, but you might want to mark that one and keep an eye on it. I usually don't dispose of mine until there is a difference of .3 in the cells, but opinions vary on that. There are ways to bring that back but for me it is just easier to dispose of the battery and get a new one.
Thanks guys. Yea I've been balance charging with a balance charger board. I think there was this one time where I charged with uneven voltages from two different batteries and maybe that's why
Great video JC, but I noticed that you're using a non-fused parallel balance board, which can be very dangerous. In a nutshell, I was charging two 4s 4200mah lipos on a relatively new non-fused xt60 parallel balance board at a rate of 1c, or 8.4amps. One of the main charge leads coming into the board either broke loose from a bad solder joint to the pcb, or it desoldered itself where it then shorted out against the other lead. My Icharger stopped the charge immediately and sounded a warning tone, but then the two lipos continued fueling the short because there was no built in fuse to blow, which melted the board and immediately started a fire. Luckily I was present when this all occured, but the fire happened within 5-10 seconds of the chargers alert tone warning. Here's a link to my experience with pictures: www.rcgroups.com/forums/showthread.php?2419266-My-first-lipo-parallel-board-fire Just a heads up for safeties sake.
SteelRainSpo - I just looked at your photos and you made me check my balance boards. I run three boards on two chargers, two of the boards have fuses and one does not. I will be replacing the board without fuses. Thank you for sharing your hard learned experience.
I have a parallel board with fuse. Fuse only protects if you have an over current coming in from the charger? Or a short from the charger leads (virtually impossible unless both are loose on the charger, accidently come off and touch)? If you have a short from any of the other XT60 males on the board then your lipos will just supply the current to fuel sparks and fire, if the board is faulty or somehow suddenly develop a short then same thing, neither situations I imagine would result in current going through the fuse part of the circuit. Real strange man. Anyhow I will take more care and vigilance when charging. Cheers
Senze I don't know what type of fused parallel board that you're using, but I'm using the Buddyrc V3 parallel board, and the Progressiverc modular parallel board. Both of these boards have 3 different fuse systems, one 40amp going into the board by the main leads to protect from shorts and over current, another 40amp for each individual batteries xt60 charging port, and resetable poly fuses to protect the balance taps. They can and will protect from any over current or short situation, to include a short circuit the lipo is powering, I've personally tested this and the fuses instantly blew like they were designed.
Mine is a cheapo parallel board, not like the one you describe with all types of shorts covered for. This is the one I have seen but not for XT60 connectors www.store.revolectrix.com/Products/MPA/MPA-XH Can you put a link here to the product you describe? I wish manufacturers would just come out with a charger that can independently charge multiple batteries (say 6) of multiple types, for a reasonable price.
Kflyer FPV incorrect, fully discharged in terms of a battery health and usability occurs @ 3.0 volts. anything below that causes heat and gas buildup (swelling) which in term increases resistance which causes more heat, gas, resistance, etc.
Well, yeah, in terms of battery health. But the term "fully discharged" implies that both the cathodes and anodes are of equal charge, chemically. Therefore having no potential difference.
Kflyer FPV technically I would agree with you. although @ that state the battery is unusable/unstable and unable to be charged again (with much longevity) aka dead cell. I guess to clarify discharged for disposal would fit your 0.0 volts definition.
Yeah, there is a difference. I left a 3S on my ground station before and it went down to like 5 volts total and didn't puff. I used the NiCd charging option to bring it back up to like 9.5 and used LiPo from there.
Kflyer FPV it is definitely possible to bring a battery back from a low voltage situation. but the internal resistance is now increased to a point that the battery should be monitored very closely as the cells have been damaged. that's why I threw in the longevity part.
I still use this as a reference when somebody new has a lipo question... God Bless you JC

Haha awesome man. I'm glad I can help and try to cover what no one else covers. That way everyone and everything is covered.
So true, if only he were still here. The best of us allways seem to go to soon, rip brother
you do such a great job, fully covering the topics you do. Thanks for all you playlists and videos!

i love my hitec x2 charger! the basics are always a plus! thanks for that you do for the hobby!
Yep its a great charger. I love mine as well. It's the last charger I'll ever need to buy.
Good information JC. I spend as much time with my batteries before and after flying as I do with my quads. Also, if you fly your battery down very low, the voltage drops rapidly, making it easier to over discharge...
You were the man and you still are the man. RIP buddy
rc and fitness what did he pass away from?
RIP BROTHER.
Yes i did, thanks mate 👍

Rest in Peace bro!
Yep your definitely the best going around for tech knowledge...another top notch video buddy, keep it up!
I don’t know if this was already said or not but, I have the 1 mini hitch charger of the same one you was holding , can I charge a 2s lipo for my fat shark just with the balance lead ?
Seriously I love how humble and helpful you are! Thanks for all these informative videos. What you vaping there?
Thanks a bunch. Its a Sigelei with Steam Crave tank. I make my own juices, just buy the products online.
Where in vid did he say how to bypass the safety on a charger
I'm charging my 30c 3000 2s lipo at 2 amps ? Is this okay?
My little reflex charger goes into cv mode when I try to charge mine it sat for a while how can I recover it
Very Interesting you do did a great job. Was so easy to learn from you
No guys, I'm not wearing black nail polish. I hydrodipped the Turnigy Evolution and a bunch of other stuff. Video is on my other channel - ruclips.net/video/BUQmcBEVyzg/видео.html
HaHa, not that there is anything wrong with that.......
Still Learning thank you for the tips

Is that black nail polish?
Hans yah I was wondering
Ha no. I hydrodipped the Turnigy Evolution and some other stuff. Video on my other channel - ruclips.net/video/BUQmcBEVyzg/видео.html
I own three lipo charger one traxxas charger spectrum charger and a Hitec charger
Can someone explain this to me? I have no experience with technology and I don’t understand this.

Yep, I agree with Shawn. You'll be fine. Thats pretty normal for batteries after you use them for a while. As long as its not a big difference.
joobok jung just make sure your balance charging as often, if not all the time. you did not say whether you are in originating post.
Thanks guys. Yea I've been balance charging with a balance charger board. I think there was this one time where I charged with uneven voltages from two different batteries and maybe that's why
Really enjoyed your video being a newbie 👍
Nicely explained
Bingo I understand thanks!
Thanks for the tips.
RIP Blue Falcon....
Well done!
nice review buddy..thx
do you even vepe bro?
Only on days that end in "y"

ok first of all blue falcon in the u.s.m.c. means buddy fucker lol
hah nice Geekhoodies sweatshirt - I have that one too (and a bunch of others)
Thanks for unstupidafying me!!
A fully discharged cell will be 0 V per cell...

Dude all u did was talk talk talk show how to do it on the charger dude
