How ProTek R/C Tests LiPo Batteries

[@racecastle]

I used to do this for a living.... this type of testing takes a LOT of time... the vid above seems to show the testing they do with a West Mountain CBA before they order in cells..... FYI.. after doing this for years I learned one thing- the test samples from Asia, were always farrrr better than the production units we received...

[@freddieparrydrums]

That’s really cool

[@jerryvolpini7987]

Well Tim, I know you've been in the industry a long time so, I'm going to assume you know what you're talking about, lol 😆

[@taimaishu-nao1922]

Love my Protek gear! Everything from hardware to tools. Not always the cheapest but it’s the brand I recommend the most for tools and hardware.

[@gourobkundu2173]

As an rc and science nerd, loved every second of this video. The bgm was also cool.

[@Cloudy_Flyer]

Protek really has some great products 👌 nice video.

[@jerryvolpini7987]

This should help people understand what makes a good pack vs. a great pack! 👍

[@papimew2672]

Ayyyyyy Raceprep is my LHS 🔥 nice to see it on the video

[@The_RC_Dude]

Great video, can't believe that ProTek is owned by Amain!

[@anastasiaelliott3716]

I use the CBA at work. They are awesome battery analyzers!

[@AMain_Hobbies]

CBA at work!? That's impressive. What type of business is this? -Brett

[@anastasiaelliott5990]

@@AMain_Hobbies I am an infrastructure specialist at a wireless internet service company. Long story short I am also responsible for all of the AC and DC systems in our network. Our sites either run fully on DC or are DC backed up with inverters. I have been using the CBA for the last 3 years to test and collect data on new types of battery's or any brought back in from the field! It is a very awesome tool.

[@jameslovasziii6917]

Love my Protek charger and batteries!

[@zonegamma8197]

really good video as always

[@DeRock401]

But is every lipo identical? Aren’t each battery slightly different? Like if you have 100 protek identical lipos are they going to be identical?

[@LawrenceTimme]

The manufacturer will be given a minimum mah and maximum/minimum weight. They will all be different but only within a few % I guess.

[@soominfoo7127]

What connector were used on the discharger, to enable 35A discharge on battery ?

[@RcOffroad9513]

This is amazing 👏

[@fizicienii278]

Nice video i did not know this about thing

[@soominfoo7127]

Do we have to discharge at max 35A for first cycle, to lower the IR value ? Or we have to first discharge at 1C ?

[@nolimitrc1]

I need to get my hands on that discharger you guys use! Im an avide rc nprc racer and you know how is goes 1-3 hits and were done and the batteries sit there smh

[@connorblue6822]

Nice love vid and I bought a lot form you guys

[@jcchaconjr]

Can't say that I'm at all disappointed with Protek packs... But I do wonder - Resistance numbers on all my packs are really low, but my Prodigy 625 always shows a slightly higher IR on Channel 2 vs when I charge on Channel 1, even if I'm using the same charging harness and balance board. Is there something in the circuitry of the 625 that could be introducing that bit of IR to the sensor on that channel? It has been that way since I bought the charger. Oh, and something else I thought of... Is it a good thing to regularly discharge cells at that high 35A rate, (similar to the the good old days of daisy-chained automotive bulbs, but of course with voltage cutoff)? I'm sure it's great for maintaining that low IR, but probably not soo good for the overall life of the batteries. Wondering if purchase an accessory like the SkyRC 35A discharger is a good idea.

[@AMain_Hobbies]

That IR reader is pretty good for a general snapshot but it's definitely not a microscopic look. For more accurate and consistent readings you might want to invest in a dedicated IR unit. For the 35A discharge, it's not done when cycling the packs; they are cycled at a 1C rate; the 35A discharge is only performed to test the performance of the pack. When you drive your vehicle you might be discharging at 35A or higher, so you're packs will get their exercise. -Brett

[@nathancunningham8717]

Isdt makes a discharger that can be set to 5A, 10A, 15A, 20A & 25A discharge rates

[@Shaun-hp2yz]

wow amain made proteck!!

[@517rctrailcrawling]

Great video 😁👍👍

[@rong648]

ProTek states; 10C is the max charge rate - 1C charge rate recommended for longest life. Other than faster charging times is there an advantage to charging at 10C?

[@AMain_Hobbies]

Charging at a high amp rate will excessively heat the pack from the inside out giving it more performance. Stock racers primarily use this to achieve more performance when motor power is limited. For context, I'm talking about 30-40A charge rates and as a side note, the batteries don't last as long with this method (when you're trying to win, it's a small sacrifice). -Brett

[@rong648]

@@AMain_Hobbies Now I know why my friend was charging at 40A, thanks.

[@omaralba2902]

Hey brother so I got the kyosho mp9 rtr my first car and when I drive it turns to the left and it doesn’t go straight what do you suggest ?

[@AMain_Hobbies]

Congrats Omar! That's a great buggy. For the steering, the servo center point may need to be adjusted and you can do this using the Steering Trim knob on the transmitter; just dial it in until the car points straight. Let me know if this doesn't work and enjoy the buggy! -Brett

[@nolimitrc1]

Do you guys sell the temp wire to go in the prodigy 66 dual charger?

[@AMain_Hobbies]

ProTek doesn't but this should work: www.amainhobbies.com/dynamite-temperature-sensor-dyn5033/p-quqwtaqqtc2xactz -Brett

[@rat2405]

I love my protek servos but batteries on the other hand tend to be short lived. I run them in my eb410 et410 b6.1 b64 and I have two stick packs that I run in tlr Scte. I have my charger set to 15amps for charging on non lihv mode

[@mikeshobbiesandrandomstuff]

I highly recommend getting your batteries made by Grepow if you aren't already.

[@MauzyrockRC]

Are there any protek non-racer lipos? Like hardcase 6s packs etc? Thanks!

[@skycorrigan6511]

Try Gens Ace. They have some quality cells

[@AMain_Hobbies]

Not many but they do offer this 6S battery: www.amainhobbies.com/protek-rc-6s-60c-sigraphene-hv-lipo-battery-22.2v-4500mah-ptk-5140-20/p-qqqvq2rqhc2cqctz It's kind of a generic pack for any application that needs a 6S, not necessary just for bashing. If you're hardcore bashing, go with Sky's recommendation below and check out the Basher series from Gens Ace: www.amainhobbies.com/search?s=gens+bashing -Brett

@@AMain_Hobbies love when creators respond to questions. Godd on Amain!

[@papimew2672]

How many amps do you recommend to charge a 6000mah Protek?

[@braco222]

The healthiest and safest is to charge at 1C. That equals to 6A for your battery.

[@AMain_Hobbies]

Like Braco said, 1C rate is safest and healthiest for your pack, and recommended for normal use. -Brett

[@jettthomas9453]

Do you need a special charger for lihv packs

[@sps-vf4qq]

Yep

[@AMain_Hobbies]

You can use any LiPo balance charger with LiHV batteries BUT, only an LiHV charger can charge it up to 4.35V a cell; any ordinary balance charger is only programmed to charge up to 4.20V a cell max. -Brett

[@jettthomas9453]

@@AMain_Hobbies what's the best charger for those packs

[@taimaishu-nao1922]

@@jettthomas9453 Grab an EcoPower multi chemistry charger/discharger. I have one of their balance chargers and I charge mine to 1C. You will get what you pay for in terms of features so you may want to consider getting one that does 35A discharging if you don’t have a discharger already. The great thing about multi chemistry is that you’re not limited to ONLY NimH or LiPo. It might seem expensive but it’s worth it if you do a lot of bashing and racing. BTW, EcoPower is an Amain brand too.

[@GrimJerr]

I have 2 that are very puffy and I have a strict charge and store regimine. can't say I am happy with mine. protek Graphine PLUS 4500mah 3cell 12.4 120C

[@thatonebeone]

nice.. you should get good cycles run out of them if you take care of it.. but there will be a point the battery will degrade but its good to get the most out of it. just all depends how you use it and want to get the most power punch of of them

[@blackhawk2302]

If they puffed up, then get rid of them. You're asking for trouble.

[@rat2405]

All protek packs puff fast than others

[@S9RUT]

Does this happen to every single battery that is sold, or to every single new battery brought to the market?

[@AMain_Hobbies]

Not all new batteries are tested this way, only the ones ProTek R/C is considering offering under their name. -Brett

[@jackdurden466]

Something about all this makes me a little more glad that I run nitro....although I would get some use for a couple of small 2S LiPo. And I guess Samsung back when was possibly a start of the intense testing. Too many burned faces. 😫

[@Apasash]

👍👍👍

Guess I should probably buy one of these lol

[@lawsiesteve1649]

Would be nice if we could get them in Australia....oh well.

I run these i have the new 4s and 2s lihv 6100’s and the prodigy charger to match

[@Barry843]

Batteries have always been an issue , all the way back to the Ni-Cad days . When a company does extensive testing like this they do find the best batteries BUT there sponsored drivers get them . . .

[@rcnoob4747]

I should switch to protek

[@singhda03]

Every protek I’ve bought has been gone bad within a season.

[@AMain_Hobbies]

Hmm. I suspect a 100% failure rate means the battery is not the issue and there is some other underlining issue. What battery model are you using and with what vehicle? -Brett

[@never-stock-rc2968]

Geared to high...

[@rat2405]

Same here every 2s lihv I have go bad even my r1 works lipos seem to puff at storage voltage or one cell dies

[@nolimitrc1]

4.35 i only get 4.30 out of a brand new pack

[@AMain_Hobbies]

Hmm, idk; maybe a limitation of the charger? The end volt is set to 4.35V? -Brett

[@nolimitrc1]

Makes sense thanks bret!

Hi

[@LosihoTTT]

The fact that you don't ship LiPos overseas means nobody outside North America knows how good or bad they really are.

Always cycle in your lipos, lowers the Internal Resistance 😎 for you speed freaks. Warm to 110 degrees and run for max speeds. NOT 4 BEGINNERS!!!
