There are always new people joining the wonderful world of RC. Many hit the local hobby shop or buy online, get home and have some fun with their RC and because of their experience want to know more about the items they are using. One area that confuses a lot of people are RC car batteries. What are all those weird numbers and letters on the pack? Why do you need to know what they mean? In this video, John will go over everything you need to know about RC LiPo batteries so you can pick, choose, use and maintain your packs properly. This is one video you can’t miss if you’re getting into RC or even need a refresher about batteries.

Another note. You are getting way better at making videos sir. I already know plenty about lipos, BUT I still enjoyed watching the whole video. That's a testament to the quality of content your now making sir. You've entertained me enough to keep watching even though I already know the info. Please keep the awesome videos coming.

I'm so glad you touched on the liars on the c rating. Traxxas is probably the only honest company. If you look at all of their batteries they're only 20-25c. Which is where most batteries actually are. None of them 50c 75c and definitely not 100c.

I was impatient and bought the traxxas 4s 6700mah Batts and duel charger live kit from my hobby shop for my xmaxx. I was going to get a charger and Batts from Amazon but couldn't wait. Anyway I have been really happy with the traxxas set up tbh, it is pricey for sure but I got 51min run time on my first charge with them. That to me is amazing and generally I'm just done with driving it now before the Batts even run out. The charger has storage mode that I use every time after I'm done driving it and the charger charges the battery's to full in about 40 to 45 mins wich is perfect. The app is very useful for seeing how well your cells are balancing aswell which is nice. All in all really happy with everything.

I prefer to run 5000mAh NiMH with a laydown battery tray between the front shock towers. The weight and low tray yield a great front weight bias for climbing and stability. The lack of low voltage cut off in the ESC gives a long runtime. Most of all, batteries are stored fully charged so I’m always ready to run in seconds.

Goldbat 3s 1500mah 100c. Super cheap on Amazon and usually get them within two days. Had tons all very strong and make it multiple years. Don't no that there actually 100c like they advertise but I do know they have way more punch than either of my traxxas 3s 5000mah batteries.

@ryurc3033 2 жыл бұрын

I usually run a 3000mah 3s ovonic, or a 2200mah 3s in the front of my trx4( and just carry a spare). I have had the ovonic for 2 years and they are both a bit puffy. Turnegy 2200 did good, going on 3 years. Been trying zee lately in my bashers lately, and have one that has held up to a 2s drag car with a 4.5 turn motor and a mamba x. Doesn't drop off voltage as much in the data log, like some other 2s I have tried. However I'm going to have to get 2 more small 3s so may be trying something new. I put xt60s on everything. Just as overkill

Internal Resistance - what are your thoughts on this? Is it a reliable indicator of the pack health and is there a universal point at which a pack should be considered "expired"? For example, I have a couple of 2s packs: a newer 3250mAh which shows ~12ohms when charged and an older 5200mAh which shows ~35ohms when charged and both 'look' fine. Is there a correlation between pack size and optimal/dangerous resistance?

@HolmesHobbies 2 жыл бұрын

absolutely it is a good indicator. but you need to know where the pack started to know the health today. while higher resistance cells aren't more dangerous, they do sag more and heat up more. the older pack has higher resistance because it is older, and maybe it also had older tech when it was made.

@NC_RC 2 жыл бұрын

@@HolmesHobbies Ah, ok, thanks. So if the Pack's history is unknown (came with a used crawler) then is it just a case of keeping an eye on the resistance over time and monitoring for sudden resistance increases?

My problem is most run times on the batteries are not true & most often are far short of the advertised run time. So you get at 4500S & it’s only 3800mha true time. I guess the higher quality more expensive batteries are more true to the run times advertised. Problem is there are so many brands on Amazon unfortunately a lot are just cheap versions. I’ve had good luck with lipos so far but definitely can tell some don’t last as long or go bad. A good charger wil tell you if it’s bad or not chargeable & why. I definitely have respect for these batteries because even now they can be kind of sketchy.

@HolmesHobbies 2 жыл бұрын

4500mah is a rating at 1c discharge. cell quality determines how close to full runtime it will deliver at 5c, 10c ,25c etc... There are plenty out there that deliver 90% or better rating at 25c.
