HCigar VT200

[HolmanGT]

I have one of these on order and I'm looking forward to it. That said, I do worry about the brass 510. Yes, in theory, if I'm careful with it I shouldn't have too many problems. Part of me wants to cancel and wait for the revised version with a SS 510. Then again, I'm impatient, so I'll likely go through with the order anyway. Hmm...

Ant,

Looking at the pictures that 510 connector it looks dark in color compared to plain brass. It may be alloyed up to something like Marine Brass or Bronze which should hold up pretty darn well. And if you know to be careful as you said I doubt you will have any problems with it.

On the other hand it has been a couple weeks already since they announced they would offer SS 510s in 4 weeks. Seems like your halfway there.

Big ''Brass-gate'' will end soon as we start usein it properly. Its proper 510 connector!

I've set mine to 14.43 Wh based on it being 11.1v x 1300mah. Is that what everyone else is using?

I've had my VT200 for about a week and a half, and I found 14.43 to be pretty inaccurate. It would signal weak battery when the meter said roughly 20% left. I have since changed to 12.77 (1150) and so far it seems pretty spot on.

So whats this value is exacly stands for? Is it battery discharge accuracy reading OR ''telling software whats LiPo capacity (mAh?) - to properly charge"? Im confused.

It's only for telling the chip what capacity battery you have installed, so it can accurately display how much is left in your battery. It will not affect anything else.

So if its just a meter (right display on screen battery state) why hcigar is saying that:

"if you want to prolong the battery life a little bit Please change to 14.43 Wh instead of default 9Wh"

Thats what im trying to understand.

I'm not sure what they mean by that, but it will not prolong your batterylife. The battery will run out when it runs out, regardless of what the meter says. And 14.43 is equal to setting the battery specs to 1300mAh, which the VT200 has according to HCigar, however I find that number to be a bit optimistic. Or possibly that the battery capacity will improve over a number of charges. But for me, setting the capacity to 1150mAh is what gave me an accurate display of the battery meter. If you would keep it at 9Wh as it was by default the meter would say battery empty long before its actually empty. And vice versa if you set a higher number than 14.43/12.77

What will prolong batterylife though is changing Cell Soft CutOff to a lower value, but that is not recommended because you might be pushing the battery past its safe limits. I am keeping mine at default 3.09V.

GOOD NEWS !!!

Silicones are comming..

EDIT:

Whoever have VT40 silicon - must agree they are quite good quality - VT200s looks same made.

You can also calculate the figure with battery analyzer.

 

[kraze6548]

I wouldn't set the voltage cut off much lower than 3.09 . Actually I set mine to 3.3
the very minimum cutoff is 3.09 for a lipo cell anything lower might cause issues down the road with reliability. I have been using lips for along time in rc applications and during that time I have seen alot of things go wrong with the batteries. From packs blowing up, to rc cars catching on fire. Majority of the time the problems came from letting the cells dip to low , or people using batteries with the wrong discharge rating. The few little things can make a huge difference with lipo .
Anyone figure out the size of the lipo. Like to get a spare . I use thunder power lipos in my rc and I'd love to find one to fit vt200 . There Batts have anywhere from 35 to 60 discharge. There not cheap but they push the power and last forever.

Would you say 3.09V cutoff is dangerously low for a prolonged use? I am no expert at all when it comes to batteries. Been trying to read up about LiPo safety and different numbers seem to show up. According to this 3.0V is the absolute minimum voltage, so I figured the default 3.09V would be safe. I would rather have less capacity if 3.09V is borderline unsafe.

Edit. I found a post by Brandon at Evolv stating that 3.09V is perfectly safe.

 

[kraze6548]

Yeah 3.09 is the min I would set it too . That's why evolve have it set as default. I was just trying to stress that going any lower is Def not recommended . Lipos are sensitive when it comes to stuff like that . The default should be fine. I just made mine 3.3 cause that's what I use on all my rc speed controlers. And if u want to extend the cycle life u can switch from max puff to max recharge in escribe . Forget what page the setting is on and I'm at work. Doing that limits the cell charge from 4.2 to 4.1 which is know to double cell life.

Finally arrived! Its much.. much smaller than i though. Cant stop digging in eScribe!

Hopefu)Hopeful those silicon cases will be out soon. It's so smooth and shinny I don't wanna scratch it

 

[Rockwell222]

I've been a little hard on it and it's finish is holding up well. I work construction so it sees some abuse, I do leave it in the truck the majority of the day but I'm suprised how it's held up. I did get some e liquid in the top venting holes. I'm very careful with all my devices and of course I do this to my nicest one.

Ill give a shout.. soon as available. (with bit of luck - next week)

@cimon Do you like those ni200 zeph coils? I never tried them because the regular occs were so terrible.
