Asmodus Lustro Battery Indicator

[Crewella]

Posting for new member @Ohmboy88 :

I got the asmodus lustro and the battery indicator goes up and down but doesn’t show were the battery life actually is and I have brand new 3500 mah batteries? What’s the problem I’m getting OCD about it lol. Help !?

ADDED: I don't have one so can't help!

The mod doesn't have a clue what battery life your battery has, it only knows what voltage it has. It's only a problem if you think it's a problem.

I can't help with your OCD, if you can't deal with it buy a mod that shows the voltage of the battery.

Ok smart one didn’t know. Now about the voltage it reads it reads 5.10 on 80 watts then how

that’s weird so the battery indicator is just gonna go back to full even when the batteries are dead ? Doesn’t make sense to me.

The problem may be caused by the batteries you are using -

Generally speaking if an 18650 has a higher mah capacity, then higher the internal resistance and the lower the Amp rating. What this means in practice is that they are designed for long run time at lower power levels - 3500mah 18650s will probably have an absolute maximum Amp rating of 10 Amps, but if could be less.

Battery Mooch recommends drawing a maximum rate of 3 Watts per Amp, per battery on a regulated mod. So if you are using 2 10 Amp 18650s (3x10x2 = 60) you should not be trying to pull more than 60 Watts from these batteries. If you attempt to go higher than this the batteries will be overstressed and the voltage they provide will drop (which will make your mods display drop). If you leave the mod to stand for a few minutes the internal voltage of the batteries will stabilise and the displayed voltage will increase. This may explain why your display fluctuates constantly.

Bear in mind that a 10 Amp rating is probably the maximum you can expect from a 3500mah 18650 if they are genuine cells from a reputable vendor - if they are unknown rewraps or eBay 'specials' then the real Amp rating could be much lower than 10 amps.

What power levels are you running the mod at, what are the batteries and where did you buy them?

That's the voltage applied to the coil from the board, not the voltage of the cells.

No that doesn't make any sense to me either. Is that what is happening?

.. and I could do without your sarcasm too, so work it out for yourself.

is this not the same thing? battery life and voltage left in the battery?

Not necessarily...

If you attempt to pull too much current from a low Amp rated cell with high internal resistance the voltage it gives out can drop so low due to battery sag that it triggers the low battery cut off on the mod. Leave the batteries to rest for 5 minutes or so and the voltage will stabilise and increase.

but that would then mean that for the period of time the batteries were recovering from being stressed, that would be the capacity left in them? the life that is in a battery is the volts it contains? a genuine question, i always like to try and understand this stuff better.
