ProTek RC Lipos

Has anyone had any experience using ProTek RC lipos, their description states that they are designed to be able to handle a 2C charge. Just wondering if they are decent quality and can really handle a 2C charge, that would be helpful between races to speed up charge time at the track.

I have the 5s 4000 20c and the seem fine - i couldn't argue at $80.

With regard to charging at 2C my new enerlands say the same but I don't do it....

Haven't heard any bad comments on Protek but im surprised you don't see alot more people using them since of their low, low price

I've got a 3s and a 5s 4000mah 20c and the work very well. They are much like my Neu pack in that the balancer almost never blinks when the are charging. I don't know about charging them at 2c though. It said that it was ok on Amain when I ordered them but in the warning sticker on the battery it said not to exceed 1c.

Here's the sticker:

my 5s 4000's are doing fine in my buggy with the 1515 2.5d one pack has 30 cycles, other has over 10 and no issues right at 20 minutes runtime on the track, i wish i would have gotten them back when amain did the $80 special but oh well dealer cost is only $5 more than that special, so its all good.


has anyone lost or puffed a cell with theirs? i noticed that under VERY hard running, and I mean HARD running, that the whole battery expands ever so slightly, its not swelling so to speak, it also didnt feel as hard as normal not squishy or crunchy just slightly soft, i dont guess it matters ive put another 20 cycles on the pack and its never out of balance, but every now and then i do notice this, temps are always in the 110-115 range no matter how i drive so i know they not over heating. I would guess im at their limits....

i have charged one of mine at 6 amps before to hurry it up before the main once and it didnt come off the charger any different than normal 1c charging , all but that time i only charge at 4 amps.



what do you plan on using them in?

Well it turns out Im not going to be using them in anything. I bought it to use in my brushless Kyosho Mini Inferno, but I ordered it when I didnt have my chassis in front of me to measure and it turns out the battery is too big to fit in the chassis. DOH!!!

well i've been running two 2s 4000mah 20c in my stampede for nearly two yrs now and theres nothing bad to say about them. Even comparing to my 6s neu energy pack, it isnt far off for its price...
