Please note that the Supercharger is absolutely perfect for the 12.0Ah battery. This topic specifically looks at the relatively small 1.5 and 2.0 Ah batteries. Do you have a supercharger? How do you use it?
You’re right - but the supercharger charges the 1.5 and 2.0 faster than the Rapid charger, but the others like the 4.0 and 5.0 charge at the same speed. I’d expect them to behave the same for all non-HO batteries, which isn’t what I found.
Agreed. That is a lot of heat and usually we don't need a pack back charged that quickly. I can see this charger being very handy for the bigger 12ah and such. Great video!
honestly i think it's probably fine, definitely pushing the limits, think if you put one of those small batteries on a grinder it would last probably 2 minutes or so, it would be hot, you just discharged all that energy in that time, if it can charge in in what seemed to be around 15 minutes by what you said, thats power going out at approximately 6 times the rate, if you look at a lot of lithium batteries for vehicles and boats they might have a 100amp discharge and 50 amp charge rating, thats 2x discharge rate, i know its not the same thing but id say it probably is fine, and most likely a lot of specs are just precautions and probably overexagerated from manufacturers, some days here are 36c so the battery would likely be too, especially if its in the sun, then you use it and heats it up itll be 40-45c probably, i'm sure it is ok, maybe the battery will only last 5 years instead of 6 or something, its awesome to see you test all this stuff though because how else would we know. love the channel its just my 2cents don't stop doing this stuff because its very interesting.
I appreciate the words of encouragement. I have an XMAXX and I actually put a clamp meter on that thing and measured a peak draw of 2kW. Comparing took batteries to a 6S or 8S pack might be pretty fun! Great idea. The issue though is that we’re comparing LiPo packs to these guys that can’t handle that level of power. Let me do some homework and that sounds like a fun topic to discover. Thanks again!
That constant voltage stage seems wayyyyy too high as far as the current winding down at the rate it does. The cell is sitting at 4.20 (or the whole pack sitting at its max charge voltage) eating over 4 amps for like 4 minutes? Overall the current is just way too freaking high. I'm sure it would be a lot of work to break down every type of battery, what cells it has, and then determine how many of them are being charged at double their maximum charge rate or charged over their maximum charge rate. 10A per cell? The 25R is rated for a 4A maximum charge rate and that's one of the higher charge rates for 18650's
Hi Cecil, sorry for the late response. This is a good question. What’s interesting is that I find that the Supercharger actually puts in LESS power into the 3.0 than it does the 1.5 and 2.0, which makes no sense to me. The 6.0, 8.0, and 12.0 charge at full speed.
Hi I had a suggestion. Doing this heat test with a 2.0/4.0/5.0 on a standard, rapid, and super charger. Seeing what heat levels do and if they get to levels that could cause early degradation of battery life would be interesting. I have a standard, rapid and super charger and I put all my standard/XC batteries in my rapid and my HO batteries in my super charger. I have noticed the heat difference when putting an XC/CP on the super charger. It gets to hot for my comfort level, but I don’t have any way of measuring the heat it generates. I typically put a small usb fan on my work bench facing the rapid charger and battery and have noticed it greatly reduces heat to touch on the battery and also noticed it charges a bit faster.
I’ve noticed that the 2.0 and 5.0 recharge at vastly different power levels. The 5.0 charges at the exact same speed as the rapid, but the 2.0 charges at lower power levels - which doesn’t make sense to me.
@@joelnrs I said that backwards. On the supercharger- the 2.0 is given more power than the 5.0. Said differently: There IS a difference between the supercharger and rapid when charging the 2.0, but no difference with the 5.0. It may be due to heat, but long story short - I wouldn’t charge my 1.5/2.0 in a supercharger. Every other battery is fine.
Nice little comparison. But 36C is about what 95F...that shouldn't be harmful to a lion at least in my experience. That seems well within the operating range to me. Would you agree? I certainly agree that it may reduce efficiency a bit but, I don't think you could consider 36C MAX temp as cooking batteries. I may not be as knowledgeable as you but, I'm certainly more competent in the field than your average Joe. And lease let me know if I'm wrong...Like I said I agree with you about the efficiency stuff and I agree that running slightly cooler in the operating range is always better but, I just don't think that 36C is anything to lose any sleep over or really be concerned if you use the Super Charger to charge your lower capacity/output m18 batteries. If you have both chargers and it's convenient enough, then sure, slap your high outputs on the Super Charger and your lower capacity batteries on the standard charger...
Right, I do agree with you. However, 36C was the external temperature, and I’m sure that internal temperatures were significantly higher. This gives me an idea. I might take out the cells and charge the same pack without the back cover and I’m curious if i will see higher temperatures. I’m here to learn with everyone else, and to share what I know. Please don’t assume any knowledge on my part, and thanks for commenting and subscribing. I appreciate it!
@@BatteryTestChannel ya that's true I hadn't really considered that. im not sure how accurate those thermal imaging guns are and if they have more ability to penetrate than a normal temp gun. but yeah it would be interesting to see the actual battery temp. I'd guess the actual lion batteries are maybe 5, maybe 10% hotter than the surface of the case. so still probably acceptable but definitely getting close for comfort. do you know if the Super Charger and M18 batts have any temp failsafes built in? I thought it would shut off if it recognizes the battery getting too hott? At least just from a safety perspective, that would be ideal. Even if it doesn't hit the failsafe though I agree always heating up your batteries to near their limit is never ideal.
@@sml2238 IR cameras have absolutely zero penetration. They strictly read surface temperatures. Emissivity becomes an important factor with IR, so it’s difficult to compare surface temps, but a before/after would be fair i believe. Far as accuracy goes, I’ve had good luck with this FLIR Pro unit.

Do you have a supercharger? How do you use it?
On milwaukeetool website it does specify that it’s optimized for the “high output “ batteries meaning the 6.0,8.0 and 12.0

The Molicel P28 and P42 have a max charge current of 8.4A so if you're pushing it beyond that you're smoking crack
Exactly, completely agree. The charger is completely ignoring ratings on the cell’s data sheet.
Can you test this on the newer batteries that are made for the super charger. Such as the 3.0, 6.0, 8.0, and 12.0.

Wow can’t believe there’s not more view on your videos
I appreciate that! This is a brand new channel. I have to find a little more time to get more content so we can have some fun! Thanks again.
