Diesel Battery Testing:

[Diesel6401]

Venom 2s 5000mah 50-100c (series for 4s)

Venom 2s 5000mah 50-100c (series for 4s)


Speed: 36.5mph
Batt 1: 127F
Batt 2: 130F
Motor: 119F
ESC: 117F
Volts: Max - 16.76vdc / Min - 14.13vdc
Amps: Max 82.90
Loaded Rpm: Averaged between 21,000 - 23,000
Watts: Max 1252.62


After run:
Batt 1: 3.80vdc,3.81vdc
Batt 2: 3.80vdc, 3.80vdc


* Out of all the batts tested today the Venom's had the largest drop in voltage, highest temp reading per batts while yielding the higher price tag. Time will tell on these. They are new and may need some time to stretch a little and settle in. I am sure the heat is related to the hardcase lipos.

Gens Ace 2s 5300mah 30-60c (series 4s)

Gens Ace 2s 5300mah 30-60c (series 4s)


Speed: 37.2mph

Motor: 114F
ESC: 112F
Volts: Max - 16.78vdc / Min - 14.76vdc

Watts: Max 1340.07


After run:
Batt 1: 3.86vdc, 3.88vdc
Batt 2: 3.85vdc, 3.86vdc


* Also brand new, these packs performed the best out of all the packs tested. They Showed the lowest voltage drop under load and provided the most punch and yielded the best speed results. They lead the group without a doubt. So far very impressed! Time will tell if they can maintain that edge.

good stuff!
in my opinion I don't thik the case on the packs will make the Venom's heat up like that..

Turnigy 2s 5000mah 40-50c (series 4s)

Turnigy 2s 5000mah 40-50c (series 4s)


Speed: 37.1mph
Batt 1: 113F
Batt 2: 118F
Motor: 120F
ESC: 113F
Volts: Max - 16.78vdc / Min - 14.22vdc

Loaded Rpm: Averaged between 21,500 - 23,000
Watts: Max 1237.64


After run:
Batt 1: 3.76vdc, 3.75vdc
Batt 2: 3.76vdc, 3.75vdc


* The oldest packs out the bunch still help up and competed nicely. These are my trusted packs and have been my fav for a while so I am kinda cheering for them deep inside. lol. Didn't do the best, but they stood there ground.

[Brushless55]

Are you cycling these packs before the testing?

[Brushless55]

and what are the runtimes, as I know the longer the runs the warmer the packs can get....?

[Diesel6401]

Turnigy Nano-Tech 2s 6000mah 25-50c (series 4s)

Turnigy Nano-Tech 2s 6000mah 25-50c (series 4s)


Speed: 36.3mph
Batt 1: 109F
Batt 2: 110F
Motor: 116F
ESC: 110F
Volts: Max - 16.85vdc / Min - 14.43vdc
Amps: Max 82.34
Loaded Rpm: Averaged between 21,000 - 23,500
Watts: Max 1310.03


After run:
Batt 1: 3.83vdc, 3.84vdc
Batt 2: 3.83vdc, 3.83vdc


* Although yielding the slowest speed which maybe a result of them being the largest of the bunch they performed very well, the keep close to the Gens Ace lipos even though the netted the lower speed.

Great work so far Dale. Keep it up bud! Super interesting thread and I like the "real world" testing. If you need me to test the MC to see if it floats the same in FL as it does NC, Id be more than willing.

[Diesel6401]

Are you cycling these packs before the testing?

No I didn't. I thought about it, but said to myself I never cycled packs before so why start now. I tried to keep somethings some what constant. Even though now I know it's the best thing to do, new boaters and rc guys don't know that so they just charge and run so I tried to think of this like a new guy looking to just charge and go and the best bang for my buck.

and what are the runtimes, as I know the longer the runs the warmer the packs can get....?

3 min timed for all.

Thanks bud.

I thought I read somewhere it wasnt advised to cycle lipos on a charger... or am I missing something that I have not yet learned? I also read that you shouldnt use the discharge feature either? I want to say I read this on a Reedy lipo package?

Seriously Dale, it will run different. The water is wetter here, which produces less viscosity and less friction, however, the prop mysteriously bites harder therefore final resulting in a boat thats significanlty faster than in your waters. If you dont believe me, you have my address. And hey, if Im wrong, Im wrong and Ill ship it back to you at your expense.

I read about it on one of those sites either rcu or rcg about it and someone mentioned to me prior to this test if I planned on doing it. I have personally never cycled my packs prior to use, but i have heard that before a few times. Maybe there should be a test on if it's better or not.

I have never used the discharge feature on my chargers before, but have used the storage feature many times. How's that work? Wouldn't it partially discharge the packs or add to the packs to meet the set storage level?

HAHAHAHAHAHA lmao Tiq, I'll let you if I need that FL water vs. NC water tested completed lol....

I wondered that too. I realize what storage feature is, but whats the difference between (for instance if you have to discharge ot get to your storage) and discharging at a certain rate and keeping an eye on it to get it to that voltage? If this ? is too far off topic from testing, Ill start a thread in the Batery forums. Just like to know if thier is a short answer.

I like your thinking... I believe I heard once that the water here is denser and boats float better.

Diesel, if you ship me the MC after tiqueman is done I'll be happy to help with testing.

I don't think it's to far off topic. I would be curious for a answer on that myself. Maybe storage reduces at a slower more equal rate ensuring cells dont get to far out of balance to each other and he reg discharge function doesn't. That's just a guess and not a fact based answer.
