I received the H.O.G. v3.1 for Christmas along with the special edition Mason40 dump tank. I currently have 4 Sony VTC 4 batteries purchased from IMRbatteries.com that I was using for 2 duel regulated mods. The 4 batteries have been independently charged as I only have a duel XTAR SV2 battery charger. I'm thinking of purchasing 4 new batteries for the H.O.G., I'm currently looking at the LG HB4 "mustard" 30A or Sony VTC5A. I like the LG HB4 for the high amperage just to have some wiggle room when building coils and capacity isn't much of an issue I assume since the mod is a 4 battery series/parallel setup. I like the Sony's because they seem to be a great compromise between amperage and capacity. What I'm looking for is some opinions from the Veterans as this is my first mech mod, I have a collection of regulated mods. Also is it a must that I purchase a charger to charge 4 batteries, essentially marrying them for the H.O.G.? Any help from the Vets is greatly appreciated. Thank You.

Enjoy the HOG. Yeah in best practices if you're going to use four batteries in a polygamous relationship you should have a four bay charger to keep them balanced. I know Mooch is currently looking at the very issue of are married batteries really a must, but I haven't seen him post any outcome on that so I stick with keeping them paired.
I'm not familiar with the "Parallel-Series circuit system" for that mod. But assuming you are using it in parallel, then you need a battery that can handle 42 amps split over the four batteries it contains. A good 20 amp cell like the Samsung 30Q should do the trick.
If you want to use it it in series then that's a whole different animal.

So the batteries I listed will also work well and may be even considered overkill? This might also lend itself to safety due to them being rated higher. Should I flip a coin or does anyone have a pros and cons for the two? Also thanks for the info so far, very much appreciated.
Based on the information I have, I say go with the Sony VTC5A

A four-bay charger is always a good thing to have, especially if your main setup is a multiple battery mod. I would recommend the Efest LUC V4 or Xtar VP4.
The Efest model allegedly can charge 4 batteries at 1amp (speed) simultaneously. The Xtar VP4 can only charge 4 batteries at 0.5 amp simultaneously, or two batteries at 1 amp simultaneously.
Hi and welcome. I'd probably go with the Sony products unless you intend to run in series mode. The LGs are great cells, with huge ampacity, but if you don't need it, battery life will (comparatively) suck. I like the Nitecore D4 charger.
If I'm understanding it correctly the Hammer of God has two parallel pairs of 18650s in series, meaning that you have a fully charged voltage of 8.4 and double the amp capability of a single battery (1.5 times the capability to be on the safe side, really). 0.1 ohms is definitely too low. With 20 amp batteries (and they should be married, not two different sets used in dual-battery mods) the lowest would be 0.25 ohms, and that leaves no safety margin really. Personally I wouldn't go any lower than 0.3 ohms.

Hammer of God mechanical mod
"**warning this device is 8.4 volts, please know ohm's law before using**
Specifications:
- 8.4volts
- Parallel-Series circuit system
- Improved Bottom loading battery tray
- Smaller and sleeker redesign
- Utilizes four 18650 batteries (not included)"
In a dual battery mod, if in a series circuit (batteries stacked end-to-end), the voltage doubles but the amps and mah remain the same as if they were a single battery. If in a parallel circuit, the voltage is the same as a single battery and the amperage doubles (really 1.5 times with voltage drop) and mah doubles.
The manufacturer is explicit in stating that the voltage 8.4 volts, but doesn't mention the amperage or mah capacity.
It's a 8.4V setup as you have 2 batteries in sets wired in series (4.2v+4.2v) then those 2 sets are run in parallel (voltage stays the same but the amps double).
It's not a common setup by any means but does get you pretty high current. Not a newbie mech by any means.
Edit: well this was a useless post as I see KenD posted the same four days ago. Lesson is read the whole thread before hitting reply
