STOP KILLING SERVOS

[@JoseVazquez-m4n]

You always scream at us like you had one two many coffees this morning 😂😂😂😂😂

[@ExocagedRC]

LoL I usually do 1 energy drink a day. I had none for this one.

[@sgtcrusher66]

lol

[@Darknynja2]

I'm guessing by the tone of this video that some people have been claiming Reefs servos are not worth the price due to failure or other issues when the issue is in fact usually not the servo but instead the problem is with the power source. I personally knew most of this info about batteries from years ago racing oval track and off-road short-course trucks, but this was a great explanation and demonstration. Reefs still make great products. Thank you.

[@proraptor4146]

I dont buy reefs anymore because I find that their gears just dont hold up over time.

[@TheAmericanUhate]

Reefs makes good stuff, they're just ridiculously overpriced when compared to every other brand on the market imo.

[@NLiteNRC]

I didn’t realize it was that drastic. Nice explanation

[@rc-daily]

Only honest battery is traxxas. No way they're pulling 35+ c from a battery that small. It would melt the wires instantly.

[@NLiteNRC]

⁠you do means some offense or you wouldn’t word it as you did. Either way I don’t care it’s a free country but if you’re going to call someone a genius then compare apples to apples in your explanation and not apples to speakers.

[@rc-daily]

@G59Cwalwur ive tested hundreds of batteries and traxxas is the only battery that says 25c on the label and the cells actually make 25c. Very few have made more than 25c but it doesn't matter when the label says 100c.... please inform me what batteries you've actually tested that actually make the c rating on the label.

[@rc-daily]

@NLiteNRC i don't take offense to what he says.... but if he says this battery says this c rating on the label and actually hits that c rating id be glad to check on my own!

[@G59Cwalwur]

@@rc-daily also how did you test these batteries and how did you get your baseline ? Did you have the device you used to test them calibrated? All I’m saying is all you guys are using absolutes but none of you took care of any variables or did the actual math . It’s not as simple as just plugging in battery after battery . Lots of variables to consider . @NLiteNRC

[@shawnjanda9775]

Thank you. This is why I don't like racing my trucks in the winter. Plus I HATE Like hell having to clean them, from mud an crap.

[@ENGIEBENJY]

I absolutely love learning videos like this! I love the way you put it across exaggerating certain parts of how important it is to listen to what you are saying. I work in the motor trade in the UK, in the winter you can service a car and the adjust the tyre pressures to the correct pressure, the next week they will come in saying you have adjusted their pressures wrong.... in the UK it can go from +14Degrease centigrade to -8 centigrade in a night. people really don't understand how much temperature affects a lot of variables. love the videos you do, keep teaching. 👌

[@aronlabbe4427]

Solid math, here in Maine we frequently crawl at single digit temperatures. We keep spare batteries inside our pockets to keep them warm. On really cold days we put hand warmer packs around the batteries in the rigs so they don't freeze up

[@Negern91]

Got a link for the warmers? 😃

[@ozzynichols]

I live in Buxton (northern York County). I feel your pain.

[@RCRoads]

You did an excellent job explaining the process. I never considered the combined load of the servo and ESC and the effect of temperature on a servo. Thanks for sharing this info.

[@toolbaggers]

That battery tester looks like it's straight out of a 1982 Radio Shack catalogue.

[@ExocagedRC]

LoL it’s a few years old for sure. But simple and effective.

[@DasE30Cuz]

Electricity is magic to me. Most of the different terms bounce off my thick skull but some of them do get in and I understand a bit. I know what I don't know so I'm generally cautious. That being said, you explained this so well that even I could grasp it. If you could do a series on a wider range of RC electronic topics that would be awesome and hopefully helpful to others. This is bringing back memories from math classes lol. I barely passed basic ones in high school but in college I got a B+ in trigonometry. It seems I need to luck my way into my particular brain matching up with the right person's way of explaining something.

[@iaqmaster]

Great explanation Joe! Learned some good stuff here today💪

[@maxpaul11]

Great video! I bet this helped many people out! Exocage teaching newbies and oldies! You rock!

[@fabriziodaurizio1009]

Simple basics of batteries and motor power requirements (servos are motors). Well explained👍 hopefully more people now understand

[@ryurc3033]

The other 2 keys to long servo life is endpoints, and not stalling on a rock for a long period of time,(while taking a picture, or waiting in line). They will overheat fast in the wrong situation.

[@ExocagedRC]

Yes this is so true.

[@jerryvolpini7987]

Great video, needed to be said! Most problems seem to be with LP servos, though. I know Holmes was having a lot of issues and thought it was their new servo, but I think we're starting to figure it out. I know the appeal of direct power is no bec, so having to use one will defeat the purpose. There needs to be more attention paid to temp so, very timely and well done video 👍

[@texomarc]

Great show, Joe! Super clear. Just the tone of your voice demonstrates the knowledge you do have on the subject. Thanks for sharing!

[@IRONCLADRC]

Throw rice in a sock zip ties on the end, throw the rice sock in a microwave for 3min. Put the warm rice sock in your lipo battery bag.. warm lipos make a huge difference! Great video EXO

[@bcochener]

@11:51 thinking and common sense is my motto as well! 😅 Great info for the community! Cheers Joe!

[@Toodles77]

I was frying servos left and right til I swapped over to a bec and a servo running at 8.4 instead of 4s direct wire. And you are correct everyone wants to blame everyone else. I think that I just finally narrowed it down to battery. I mean usually when it fries em it’s like 30 seconds into a run with not much load. I’m running the crawlmaster v3 with a team spec revolver. Seriously I fried 3 servos now I almost don’t want to send this last one back

[@original_M_A_K]

This sort of stuff im really not good with, thanks for explaining it, makes alittle more sense 🤜🏼🤛🏼

[@kg5nja693]

That was a great video and with tons of information. Thank you

[@old-rcplane-phart]

I love my esr meter! Owned 1, since racing lipo's years ago! Built my own servo checker-tester + torque meter. Batteries, whoever really makes the smart batteries are really close to their actual 'C' ratings.

[@old-rcplane-phart]

Also, always remember to discharge your lipo batteries down to storage charge voltage. Usually 30%. Keeping a lipo charged over a period of time, a week for instance weakens the battery, & it/they won't hold AS much charge next time, & in rare instances CAN catch on fire. ANY battery that had 'puff' to it, destroy it! It's a bomb waiting to go off! [Ask me how I know].

[@mikeshobbiesandrandomstuff]

[@FatherandSon_RC]

Thanks for this! I am literally going outside to bring our battery box inside so they stay warm and are ready to go when we want to run the cars in the winter.

[@LetsGoRCn]

Appreciate the info Joe 🫡

[@AnySumptionBanter]

Temp not only affects battery but the esc. The other bottleneck is the wires. All combined create problems in extreme weather. Yes, it was known smaller batteries were creating weird back flush of electricity for lack of technical terms

[@josephphillips1692]

Thank you Joe I learned something about batteries I didn’t know or realize! I knew heat effects them but I didn’t know the cold is the same! you rock!

[@DubVredneck]

Hey Joe burnin up servos also can be from esc amps output rating being lower than combined load of power draw from motor and servo/servos i fought the under power problem fir 6 dang months n i burnt up 5-6 motors and 4 servos and 2 mb100 esc's b4 i figured it out n yeah this video is 100% correct im just adding info i learnededed financially and time sriving tiny truck loss And thank you for this video because it's helping a bunch of folks 🤘💯 thats why i started watching ya no bs strait shootin vids

[@FracturedNinja]

It’s interesting seeing you talk about temperature… I came to the RC world from the off grid camping realm where lithium based batteries are used frequently and a major topic of conversation in this area is temperature. I was very surprised to see how infrequently temperatures are mentioned in the RC world.

[@thatprcrawlerguy187]

Interesting. That’s probably why here in Puerto Rico we rarely have servos dying. It’s in the 90s year round

[@lepunkorbeau]

there is also the grease inside the gears that solidify with the cold, and can smoke the servo's motor, or esc for the brushless ones.

[@steventurner3901]

I'm very interested at this. I've never had the problem personally, but this is very useful INFO! Thank you sir!

[@RON4RC]

What a fantastic vid bro never knew it was that bad temp wise... Like what an eye opener . Thanks for the understandable vid RC brother ❤

[@OwenBuckingham11]

Solid explanation and demonstration 🫡 My only comment is the wire leads and extra plugs on your battery tester will have some effect on the readings. This is also true on the RCs themselves. Ive seen folks with multiple battery adapters, or thin wires to the ESC, all of this limits how many amps can be drawn. If you're trying to allow your vehicle to pull more amps, you need the wire gauge and good connectors to back it up. This is why 1/10 and 1/8 race vehicles use 5mm bullet connectors, and many people are using XT90 connectors on 1/10 rigs, throw out those deans plugs!

[@ciprianwinerElectronicManiac]

Good video, this problem applies to power tools as well, cars etc...

[@JasonChilson-r9i]

My friend you just blown my mind I know nothing really about electics and now I know why I'm having problems in my winter running lol

[@AsurasWrath164]

🤦‍♂️

[@StubbsRC]

This is also why we rate things in watts. And why I run 4s in most my comp rigs with these little batteries. 33% more watts available

[@Prince_Pig]

Really eye-opening demonstration 👏🏼

[@rcjunkie260]

Happy Holidays everyone!!! I've been using women's stockings to keep my lipos warm while running. I start with cutting the foot off at lenght for the lipo to fit in with extra room. Put a knot in the next section of the leg cut from the foot. Then cut so the lipo fits in with some extra again and make 3 to 4 layers of stocking. Your lipo will not get cold. It's like a sleeping bag for your😊 lipo. I know it sounds weird!!!!😂😂😂Give it a try after laughing at this😂😂😂

[@callsignmohas5190]

For someone like myself is only been into the hobby for a little over a year. Everything starts off as just fun wanting to drive a car but eventually you start getting into the weeds with stuff like this. I don’t think I have the best understanding of Lipo batteries in their discharge. Could you possibly do a video only about batteries and how to pick the right one for the right vehicle for the right type of driving?

Well, actually Joe... *pushes glasses up on nose* Just kidding! Thanks for all the info man. 😆

[@theoalbert897]

I'm gonna keep watching but c rating on a known brand name battery is pretty accurate.. plus you gotta take into account different types of batteries graphene batteries have a much higher continuous current rating than a regular lipo

[@rcarty419]

So do you think k the 850 tattu is good enough or too small……37 killed it which is crazy!! I’m always out in cold like a lot of dudes! I’m ready to unhook my good servo and go with one that isn’t direct power after watching this! Going to shop becs as well!! Great info!!!

[@michaelglass8546]

I have a lipo question, i used to run a traxxas brushless e revo with the traxxas batteries which i think had a c rating of around 30. They would get hot and the truck was a bit down on power compared to some off brand 100c battery. I belive what your saying about c rating being marketing bs, but what im wondering is why did the 100c batteries make such a diffeence then? Or is it maybe the 100c batteries were actually 30c. And the 30c Traxxas packs werent actually 30c? Just curious here if someone can explain. Happy holidays everybody !

[@NLiteNRC]

The only time my batteries get hot on my racers and bashers is if the MAH is not large enough and or I stay full throttle a lot and pull max draw for extended periods. Or the whole system is not big enough for the type of driving you are going. There are so many variables in this question it impossible to give you a correct answer for your situation. I do know like I said if your at max draw on your battery most of the time it will heat up.

[@TheAmericanUhate]

So if you were to run 2 small 650mah 4s packs in parallel, with a direct power servo, would you run the servo direct power off of only 1 of the batteries, or both? Also how do you run a direct power servo or BEC off of a series battery setup?

[@alfredyost7972]

If you stall a servo you can have problems too. The cheap amazon serves die if you stall them. However the high power serovs if stalled will draw more amps. Thoughts?

[@blakemullins1903]

So here’s a question for you Joe would it be smarter to run a direct pwr Servo with its own battery source like a small 3S and then run a 3S separately for ESC and motor? By the way I’m in Michigan and I just don’t use mine in the cold. Winter time is for building and testing inside.😏😁

[@ronaldwriston1546]

Now I’m wondering how I’ve been getting away with it so well.

[@chrisjames483]

This is why i heated my 1\10 scale race packs with a battery warmer.

[@dillonbuckley5063]

I don’t have to worry about it. Savox 2290 6 years and not a hiccup

[@shadossss]

Ok but my question is when I’m out crawling in the snow and cold is there something is can do to keep the battery somewhat warm? I was thinking putting had warmers on them/next to them/around them. Obviously I won’t let it get too hot but is this an option??

[@paintendaveextremecollisio8057]

Good informative video but does the type/ size of BEC mater ?

[@boduke9428]

I'm not really into mini anything. Even my Groms i generally cram the biggest battery i can into all my stuff. Coincidentally i rarely have servo issues. Even stock servos have held up really well. I prefer bashing to changing batteries every few minutes.

[@Matt-it8jh]

So for someone who doesn't compete just crawls for fun. Am i correct in thinking running a bigger battery, 3s but like 5,000 milliamps is a better option. Also if im running a fusion pro, how do you wire in an external bec? I just built a four wheel steer rig and i know i need more power to my servos.

[@ethaneggloftis]

Great video Joe, I get this gist of smaller batteries in cold can cause problems but im unsure what to take away here. Got me fearful to run in the cold now lol. Direct power bad, BEC powered good? Smaller batteries are okay if it’s warm or can still be problematic either way? What’s the threshold for battery size vs temperature??

[@ohnoadventures]

👍👍😃

[@Hairy_and_Scary]

Thanks Joe!! Great video. Where did you get that meter? I'd like to have one so I can mark my batteries with the info.

[@snörre23]

Since Mr. Exocaged does not reply, please can anybody enlighten me how it kills the direct power servo when it does not get enough amperes ? As a layman i would have assumed it will move slower and weaker or influence the motor when both don't get enough power - but kill the servo ???

[@StubbsRC]

But why test them not full?

[@ChunkyC_RC]

Preach it brutha 👍🏼👍🏼

[@VS666]

the hardest lesson i learned was after almost frying a $300+ AFGRC 5th scale servo. yes it's rated to 16v direct power, HOWEVER...if you plug it into your 4s battery that is in series with another 4S, now you have 32v!!! immediately started smoking and boy did I panic. i got very very very lucky and unplugged it fast enough it didn't damage the servo but yeah, your balance plug becomes 32v if its connected to another battery in series
