Romisen RC-T5 burned out driver

[qlong]

Hello, after 5 months of reliable use, the driver of my Romisen RC-T5 short thanks to my buddy inserting the batteries in backwards.

After searching on DX and KD for a couple hours, I realized I haven't a clue of what I'm looking for. lol

Is there a replacement driver for this light or another which will run the light brighter?

Thanks :huh:
Lon

I'm seeing a lot of 1000ma boards maxing out at 4.2v, was the old one even 1000ma?
