Red Sky Mods

From what I've heard, a high drain on a good vv is fine. If you run at 4.2, the mod stops working when the battery reaches ~3.6-3.7v. Therefore it is at the perfect time for recharging. I may be wrong though. (probably am)
All i have is AW IMRs with the exception of some batteries I never really use.

Ahoy, good morning all

7:18??? Are you alright Cappy?

 

[tybin]

my imr's do not stop working. i take them out and test them with the multimeter though

Afternoon shipmates! Stopping by to check in... Having a blast on my trip! Hope everyone is having a lovely Tuesday.

Ben's right. That's exactly what Brad said. By "stop working" he doesn't necessarily mean STOP working. He means they don't supply power once they reach a certain point on VV mods, therefore they never over discharge which can be quite disastrous for IMR batts. If you have the voltage set anywhere above 4.2, they will no longer supply power once they drop below that level.

Ok, I may be wrong as well, but stacking batteries you double the voltage. So two 3.7v batteries will have the potential to provide 7.4v. If you have your VV device set at say 5 volts, then as long as the regulator gets at least 5 volts it should keep running. So with this logic, the batteries would have to drop below 5v, or 2.5v each, before the regulator would not get a high enough voltage to keep running.

Is this wrong? and if not, then there is nothing that I can see to keep them from over discharging unless you set your regulator voltage to double whatever you want them to stop at. 6.6v would shut them off when each hits 3.3v for example.

The extra bonus with the Cutlass is that you can easily avoid over-discharge by simply checking the voltage (don't forget to remove your atty first!)

and to flip the switch back before screwing the atty back on!

I run mine on 4.3v with AW IMRs and I think it stops working at around 5.x, forgot the exact number but definately under 6v(I think.. I'll verify later). So I think it stops much before battery power reaches the set voltage.
For all IMR users, do you swap batteries randomly or at certain voltage?

And I read few times in different threads about mah ratings on IMR, and I heard IMR uses the closest-to-factual mah ratings whereas other brand batteries tend to be exagerated on their ratings.

I've been always wanting to ask to verify about this too.
Does using High V + High Ohm setup give you longer battery use compared to Lower V + Lower Ohm setup given that the wattage is the same on both setups?
For example, 5.91v with 3.5ohm atty would give me the same 10 watts as having 4.47v with 2ohm atty setsup. But the difference is 5.91v+3.5ohm only uses 1.69 amps while 4.47+2ohm setup needs 2.23 amps to get the same power. So less current drawn = longer battery use. Is this correct?

Yes, that is correct, Chet. Full charge on 2 batteries is 8.4v. The regulator uses some of the power ( hence the max possible setting for different types of regulators ), and brings down the voltage to the desired setting. The lower you set it, the more power gets wasted ( converted to heat ). It's not a huge difference in runtime, but on my linear vv 2x14500 box i can get up to 1.5 hours runtime more by going the hv way. I dont have any switching regulator vv device, so cannot comment on those, but they stay cooler and have better runtimes.

Totally agree, one of the reasons I started using switching regulators was the significant increase in longevity of the batteries as all that power was no longer wasted as heat.

I don't think the way you supply wattage matters too much, 8 watts is 8 watts of power, but you also do not want to overtax the circuit by drawing too many amps.

Well I hate to do it but I have to report another casulty. Someone dropped my mom's RSM at work today. Popped the bottom cap off and left a little ding in it but it is till working.

Cappy I am sure it has been posted here but to save a little time is Gorilla Glue (wood kind) ok or would you recommend another type of wood glue to glue the bottom back on. Thanks

 

[pchela]

It's a bad month for the RSM fleet.

We're a group of clumsy pirates.

 

[cba191]

I'm keeping mine in a pillow bow til this storm blows over.

 

[pchela]

Good idea. Everybody keep their RSM's in padded carrying cases till the seas calm down.

That is why I am soo happy with my tacky looking lanyard.

To be honest I feel very fortunate that it wasn't damaged more. She thought it was broken because the person that knocked it off the counter accidentally turned it off also and in her distressed state she forgot to check it. She came home in a panic and tears. Once I saw the switch was turned off she was very relieved. So was I I didn't really want to have to lend her my Cutlass untill hers could be shipped back lol.

Anyways a little glue and she should be almost as good as new. Yes she will have a scar but aren't scars really just reminders of lessons learned?

 

[pchela]

You should check in with Cappy before you glue it in case he has a better idea for it.

 

[fright88]

Yeah I will wait to see if he responds here. I know he is a busy person so I will hold off on PMing him for a little while.
