OK so ordered the smart battery mod from FPV along with this charger:
Skyrc AC/DC D100 Dual Balance Charger/Discharger for 1-6 Cell LiPo/LiFe/Lilon/LiHV Battery,1-15 Cell NiMH/NiCd Battery
I'm educating myself more on LiPo/LiHV tech and also how varying battery configurations perform. Can anyone answer some simple questions for me? Or point me to any resources where I can read more?
For example's sake, the Nanotech 1.6's that come with the kit are rated at 14.8v whereas the OEM DJI battery is 15.2v. So how does this play when wired with the OEM DJI battery? Do they just kind of balance each other out? Or does the DJI battery charge the extra bats a little? Or does it not even matter because you will burn that voltage difference off quickly after takeoff? Does having varying voltages in a 3 battery setup do anything? Or is it the same as having varying voltages between cells in a single battery pack? Is it required to match the amount of cells for all batteries that are used together? Example: DJI battery is 4 cell and so is the nano-tech 1600.
- I see that some are experimenting with splitting up the 4s to 2x2s in series and then connecting them in parallel to the XT60s on the modded DJI battery. Isn't that just six in one half dozen in the other?

- How does the C rating in the extra batteries effect the overall performance of the system? Is having more useless after a certain point?
- Does using LiHV pose any dangers or cause harm to the DJI battery? I've read that LiHV is closer to the OEM battery as compared to LiPo, is that true? Why?
- Any tips so I don't blow my face off, burn down the house or have a Concorde like disaster with my P3? Any golden rules when connecting and trying out different types of batteries? I'll be reading up as much as possible but I haven't found a thread that explains the intricacies of batteries on a modded P3.
Thanks guys and looking forward to tinkering and pushing even further.
