Basically you have two options with a driver for a P7 2 x li-ion cell
set up
1. A cheap Chinese made driver from DX or KD. These drivers have a
bad reputation for being over specced, unreliable, no customer support
and slow delivery times. But they are cheap.
Personally, I have used these drivers and have had no problems with their
reliability
2. A US made driver, the Shark Buck 3A or the HipCC boards. Good quality
reliable, does what it says on the box and the makers stand behind their
products. But they are more expensive than the Chinese made ones
3. There is a third option and that is the Der Wichtel P7 board. If you read
through his sales thread, another rock solid board. More expensive than
the US made boards but you do get multi-levels and the wires already
soldered on for you
You can find his sales thread in the Custom BST
section ..... use the search function.
Essentially, what you pay for is what you get :devil:
Happy modding and let us know how you get on :thumbsup:
BTW, if you used 3 x NiMh rechargeable cells in a 3D Mag, you can direct
drive the P7, maybe add a D2Flex for multi levels :naughty:
