I didn’t get an answer in the “No stupid questions” thread, so I’ll ask this one separately:
1) Can you DD an XHP70.2 with 3S/9V?
2) Driver recommendations for a max-effort Trustfire TR-J19 – running 3x XHP70.2 P2 1A (likely 2S/6V)?
I have a TR-J19 which can run either 32650 2S or 3S, with a really bad driver in it. It’s been collecting dust since I bought it, and I want to update it. It’s massively heavy so it can take a lot of heat.
As a side question, can anyone recommend a driver for a Trustfire TR-J20? It’s running 12x cool white XM-L2 LEDs.
3p XHP70.2 directly driven off 3s? We’re talking about 2.35V/battery @ 60A. The battery will be killed when treated like that. So…let’s think about more sensible 30A. 2.21V. That would require huge resistance in the host. Without overheating. No, it won’t work.
If you’re into extreme modding, you may convert XHP70.2 to 3V and run them in series.
Lexel has buck drivers for CFT-90. Maybe he could tweak them to suit your needs?
