LGDBHE21865 Vs Sony Vtc5 for DNA30

[jclifford94]

My Sony battery had reached the end of its life cycle. I'm trying to decide between buying another VTC5 or going with the LGDBHE21865 35AMP. Has anyone experimented with both, and how man I tell which will perform better in my DNA30 device?

The Samsung INR18650-25R should be on your list. In my experience, it outlasts the vtc5 and the LG he2 used in my dna30 hana.

And authentics should be easily found for a reasonable price unlike the vtc5.

The Samsung only puts out 20A.. Won't that mean a weaker hit?

 

[beckdg]

3.5V (nearly dead battery) putting out 30 watts (max output of a dna 30) is only about 8.6 amps (rounded up). since the output is regulated, you'll get your 30 watts regardless... and 20 amps continuous is overkill for your mod. it'll be fine. you'll love the 25R just fine.

I have both batteries the Sony lasts longer by far the lg hits hard but drops fast also the he2 is 20 amps 35 amp pulsed

The LGs are 20 amps continuous, not 35. They perform great though. I only have VTC 4s (of Sonys) to compare with, not VTC 5s, but the LGs are better performers. Also, just to point out that mAh rating isn't everything, they last considerably longer than my 2900 mAh Panasonic PFs.

The Sony VTC5 and the Samsung -25R last about an equal about of vape time in my Hana.

I agree that the LG HE2 does not last as long as either of the aforementioned batteries.

Here are some discharge curves for the Sony and the Samsung as well as the HE2:

When discharged at 5A the Samsung and the Sony actually are much closer.
The Samsung actually stays in a vape-able voltage range a little longer than the Sony. Making it an almost ideal battery for a 30 to 50W regulated mod like the DNA30 or the IPV2.

And, at $8 a cell a much more inexpensive option than the now pricey and hard to source VTC5.

I was a bit skeptical at first but after a few weeks of using the Samsung and the VTC5, The Samsung is a contender when used in the 5 to 15A range.

All three of VTC5, 25R and HE2 last about the same in a DNA30 application (up to 10A), according to all objective testing whose results are available publicly. The VTC5 has slightly better thermal performance than the 25R and probably the HE2 but I have not found thermal charts for HE2.

Yes that's a good point. The rating on those Panasonic's are based on a discharge down to 2.5v, I believe. Most regulated mods will cut off before that voltage. Also some of those high capacity Panasonic batteries tend to give a lower voltage output throughout their range compared to some of the competition.

For example a Panasonic hybrid 2900mah based battery (Keeppower 2900 mah) vs a LG HE2 based Keeppower 2500mah, shows the LG based battery holds a noticeably higher voltage @ 10A discharge until it's almost empty.

Thank you all for all the info. I noticed the Samsung is not protected though, does this mean I need to be careful not to overcharge it? I'm using a VaporShark rDNA 30 and my builds are always .9 - 2.0 ohms.

 

[Papa Lazarou]

Very few (if any?) high amp batteries have a protection circuit on them. If you use a good charger it should avoid overcharging. I have a Nitecore i4 which I'm happy with and doesn't seem to overcharge any of my batteries, but other brands that make decent chargers include Pila and Xtar.

 

[jclifford94]

I would be charging it using the passthrough on my rDNA. I know the VTC5 is protected. Not sure if my rDNA has overcharge protection built in.

The Sony us18650vtc5 is NOT protected.

Your vaporshark has a proper charger and protection circuitry.

 

[Papa Lazarou]

You can tell protected batteries because they are usually 2-5mm longer than unprotected 18650's (i.e. 67-70mm long). VTC5's are normally sold as a bare cell (green wrapper) and these do not have a protection circuit.

I should think the built in charger in the mod will shut off at the correct voltage, but I can't say for sure as I've never seen it tested.

Maybe consider that VCT5's are getting hard to find. And if you do find one, you might have to pay more than what your DNA30 cost. That's if it is a clone DNA.
