    Default Ryobi BCL14181H One+ lithium battery charger help

    Blew up the Ryobi BCL14181H One+ lithium battery charger on the weekend. Found quite a few bits damaged: IC1 (SG6848 switchmode controller) shorted, R2 470 ohm open circuit, R3 220 ohm open circuit, a pair of Schottky MBR5200 diodes short circuit, Q2 MOSFET 9565BGH blown, Q1 04N60 MOSFET short circuit. One bit I can't work out is the resistance of R4 (near IC1) - is it 150 ohms (SMD marking "151") - can someone confirm that please?

    A SMD resistor marked 151 is 150R

    My problem is the resistor is burnt & open circuit, and I can't positively identify the numbers on it. From other grainy, out of focus pics on the net it appears it might be "151" but looking for confirmation from someone with one of these devices - sorry should have explained that in my original posting.

    Not that it applies here, but these Chargers have a high failure rate, and just outside of the warranty period. Keen to see how you go.

    Tell me about it. This'll be my fourth. First three inside warranty, this one outside. Caved and bought a new one, one of the compact versions, and added heatsinks to the MOSFET devices to hopefully mitigate their stress and ultimate destruction. I'll still have a go at repairing the old charger though, would be handy to have a spare.

    Hmmm maybe that is why mine was only $35 brand new from Bunnings - marked as superceded.
