Help with particular resistor identification

Hi, I have an imax b6 (cloned) battery charger and I've blown the resistors by connecting a battery in reverse polarity. One of the resistors is unidentifiable due to the burn but here is a picture of the same device, can someone please tell me what specifications these resistors have from the colour banding? I'm a bit confused by the small one in particular as it looks like it starts with a black band. Thanks in advance ..

There are different versions of IMAX B6 chargers and clones. Hence the emitter resistors for your board might be different.
Typical values for the resistors are 0.05Ω 5% on the left and 0.5Ω 5% on the right (Green Black Silver Gold).

Post a photo of your board.

Thanks Mr chips. This photo I uploaded is the exact same board as mine. On mine I can't read the resistor bands as they are blown. Are those values you mentioned correct for the board in the photo? I'm not very good at reading the color bands. Cheers

Resistor colour codes do not begin with BLACK.
My guess is that the one on the left is 0.05Ω 5%.

Here is another view.
