Does this seem right? It's a brand new battery from Amain (it was super cheap to be fair) and this thing only lasted for like 10min this doesn't make sense at all. I charged it a few hrs after it was delivered and warmed up to room temperature and it only read around 1500mah didn't think anything of it.. ran it around my house for 5 min and then charged it back up for work (a few guys from work bring their trucks in and we screw around in the empty field). I killed it at work after 9min and then when I got home I charged it and this is all it took. Is the battery just THAT bad or should I return it?

What was the voltage of the battery before you started charging it? What's the LVC set to on your ESC? What kind of vehicle are you running?

And is it not the charger? I see a cheap copy of the original B6......

"LiPro".... LOLz

10 min run time is about what I get from most of my cars, sounds normal to me, especially if you have installed upgrades which might draw more power.

I have a 100c Lectron pro 6s 6500mah for my arrma outkast, and its an awesome pack. Also wasn't cheap either but a 6s usually isnt.

I'd say you got a bad battery or the charger/cable is having issues. What was the battery voltage when you first got it?

lol.. i know it's a weak charger, but i've had it a few years and it's done well with my other "liPro" units.. lol just this battery is a def no go. The truck is a Losi Tenacity SCT 4wd Brushed model. honestly.. i can't remember the voltage at the start, i'll have to double check it after i run it this morning.

I guess i'm just more used to my RB6.6 with a battery of the same size i could get almost 25 mins out of that thing. To be fair this is my first experience with a 4wd so maybe i'm just expecting too much.


I did order a Spektrum battery (When i ordered this thing on Amain the unit i wanted was out of stock) and the nicer spectrum charger to go with it.

Battery is fine, car is going to limp mode after so many minutes.. sigh now to figure that out. 6.8.0

THe 4wd car is going to drain a battery a lot faster than running a 2wd... I run a 6000mah / 120c in my Tekno baby truggy and with a 10 min main I usually will have 25-30% left in the battery.

As far as your 'limp' mode... I am guessing your esc is hitting low voltage cut-off... you may have it set to high at 3.6v per cell as you stated the battery was ready 7.2v. Check you esc for what it is set at.

35c battery is not very high for a 4wd SCT vehicle. The other problem you might run into is brushed motors on something like a SCT will overheat after less than 10 minutes because of their inefficiency. I had a Losi 2wd SCT that couldn't make it 8 mins without overheating.

If you're only getting 10 min, test the temp of the motor. Having the battery going into LVC this quickly, might be saving your motor.

Pretty sure what's happening is you punch it, which causes a huge current on the battery. This creates a voltage sag on your 35C battery that trips the LVC on your ESC. This ESC is either Lipo or NiMH. No documentation that I could find on what the LVC is set to.

Don't think there's a defect or anything wrong with the battery other than it might be the wrong battery for your application. But maybe not if running longer causes your motor to melt down.

You don't know how long the pack bee sitting on shelf in Amain. After 5 min of running is not enough to judge. Run enough till model cut out. down to 3.2v. do it 3 times. 4th time do a Balancing charge fully. if it doesn't improve send it back

Do not attempt to return a battery without verifying the capacity first!

You do this by driving the car to LVC, then charge it and see how much capacity was charged into the pack.... should be reasonably close to the advertised capacity, though keep in mind that many LVC's are set to cut off at higher voltage so the battery won't be fully discharged.

If you reduce your LVC to a lower voltage to extend your run time, then this will significantly reduce the lifespan of the battery:

Also never discharge a Lipo below 3.0 volts per cell. A lot of esc's have a 3.2v/cell cutoff setting which is safer as the esc doesn't see individual cells.

He's got a simple brushed ESC. It only has a Lipo and NiMH mode via jumpers. No idea what voltage Dynamite uses for low voltage.

That battery is bad and way underrated for that truck at 1231 mah to recharge.. and its a lectrone not a LiPro… they used to be a very good brand I have some that are 10 years old and still run strong 3300mah with 45C . and you can not send a lipo back in the USA ..

Did you read the post you replied to? They specifically said run down until it cuts out several times to verify. If it doesn't improve, return it.
