Critter Mods

Roger on both. I think I saw someone doing a "paraseries" build like that somewhere.

So if they charge evenly it sounds like they're charging in parallel, right? Hmm, how would Device Monitor know they are separate and not just recognize them as one? I feel like I'm missing something And bridging for 2 cells but using 3 is just right out. Four shalt thou not count. Five is right out.

Hi guys, I'm returning to modding since my last builds with dna25's and excited to try some things out. My design will have 2 2x700s powering a dna250 board, and I have seen some conflicting answers here and elsewhere about wiring so I thought I'd come out and ask. FYI I vape (don't laugh) 0.1 ohm Revvo coils at 45-50W but occasionally bring out a squonker or an RTA from time to time, never above 70W. Q1) Some people have said to wire in series, and I've seen T1—T4 bridged with B+, and it's getting lost in the way my head organizes things. Here's my plan, please tell me if I'm wrong: I'll bus the B- with the two negative ends of each battery. In fact my design has a copper "endoskeleton" so I'll use that for bridging/busing, solder to B-, and as Gnd for the 510 **[subquestion: can I still use that for up, down, fire switch negatives?]** Then, can I wire cell 1 + and cell 2 + to the board in the "1" and "2" holes in the first image? I don't see a reason to use the 4 pin connector, electrically it should be equivalent, right? I'll throw a pig tail into the GND hole from my B-/Gnd endoskeleton just to be thorough as well. This doesn't seem like series or parallel, but individual--do I need to bridge positives for any reason? Seems like you'd lose the individual cell monitoring and charging. Q2) If each cell's positive is separate, then what is B+ on the backside of the board for? If you were to use their suggested 3 cell Lipo with the connector, what, if anything, does the B+ become? Or is it just there in case you want to run a parallel/single cell? Q3) If I were to run an LED for a flashlight, is there a "combined" positive to tap into? I could tap off of just one cell, it won't draw much or be used much, but without busing the positives anywhere (if what I said in Q1 is true) I don't see how to draw this evenly off the batteries. I don't like the idea of creating imbalance in the mod, but if it must be done.... Just to clarify, this would be for a flashlight, not connected to the fire switch. Here's my old dna25 builds from a while ago, looking forward to getting back into it and thank you guys for any help you can give!!

I see people bridging--doesn't this combine the cells so you're running 2, 3, or 4 in parallel? The cell monitoring won't work at that point, right? New to DNA250, excited to start building soon and I've been wondering this same question. If what jsforder said is true, why would they bother separating out pins and not just solder directly to B+ from the parallel'ed cells, right?
