Kraton Question on batteries

[basher27]

I’m looking at purchasing the new Krayton V6 when it comes out soon. Since I have a handful of 3S Arrma vehicles wondering if it’s a problem running with these two batteries? You’ll see that the C rating is different. Everything else is identical. Is that going to be a problem? I obviously realize it’s not ideal wondering if there’s any harm to it though

For series, mismatched c ratings are ok, just not ideal. The bigger problem is if that 5000 50c battery can provide the amps without heating up. If your easy on the throttle, likely fine till you get some proper lipos.

I personally would never run mismatched batteries. All you are going to do is destroy the weaker battery.

-edit- Whenever running batteries in series both batteries must be from the same manufacturer, the same series, the same capacity, the same c rate and the same age( you do not want to run a brand new lipo with one that is 6 months old with hundreds of cycles on it.)

Mismatched batteries are frowned upon, like this

I would also ditch those spektrum batteries and get a much better brand of batteries, like SMC, CNHL, Ace Gens etc.

Series MUST be same capacity if pulling near full capacity. Voltage can differ with no ill effects. a mismatched C rating will push the lesser lipo harder, causing damage before the stronger pack.
Parallel MUST be same voltage. Capacity can differ. C can differ, but if you push the limits of the combined back, the weaker battery will take more damage.

If pushing any of these, you risk degrading the weaker battery faster than the stronger. And this process accelerates if you continue to push. Thats why its important to run matched cells in our case as we tend to abuse the fickle and dangerous product.

Good rule of thumb is just keep everything matched- voltage, C, age, cycles, brand, capacity. This maximizes the longevity and minimizes risk of use.

Id run those lipos no problem, but with caution. I gotta play with new toy after all! Set lvc high and be easy on the throttle. But I would replace them asap and not use them again in that configuration after.

A don't do this even though I do tip - mismatched chemistries can be used together in series or parallel if the min, max voltage, amp draw and capacity limit is all observed. But don't do it. Let me do it so I can have a lipo powered turbo button on my 18650 go kart. Too much fun dangerous for you.

Yup it's funny watching people freak out when you show a pic of you running a 3s and 2s lipo in series lol. It amazes me how many people have no idea how electricity works. I remember learning about batteries in parallel and series in like the 5th grade I just assume that not everyone learned that in school or that they no longer teach it.

I seem to remember learning basic circuits, like a battery, light and switch. But don't remember anything more in depth like parallel/series. I learned the hard way, by making sparks and electrical fires when dad wasnt looking.

In my defense, he started it. Have a remarkably vivid memory of him handing me a spark plug when I was about 5 then turning over an engine. And again with a magneto after that. Do you know what 20,000 volts feels like? I do.

Later learned to remove rings around big batteries. Pos and neg of a 72v lipo pack touched my wedding ring, melted a divot into the tungsten band. And my finger. Like I said, learned by making sparks and fires

I bet that tickled.

You will get the performance equal to the lower rated battery. It will punish both batteries, but not thr end of the world.
If you just want to noodle around than don't push voltage cutoff or lots of max throttle.
