BT-E6000 fuse replacement

Just like on the BT-E6010.

First, check that the following are true:

• The battery is in balance and not in deep discharge, nor is it fully charged
• When you plug in the charger, the LEDs on the battery start blinking at least for a few seconds as if it were charging
• However, the charger is not pulling power

To double check that it is indeed the fuse:

• Multimeter in 10A current measurement setting
• Use the probes to bypass the fuse as shown
• Notice that you charge at around 4A / 170W

Remove the screw near the fuse to provide good access. Then use the Dremel at 15k rpm with the pictured end to remove the solder mask from the PCB along the two long sides of the fuse.

It is important to keep the tool level to remove the solder mask evenly BUT not remove the thin copper layer. If you remove too much copper, the whole thing is fucked.

Put the screw back.

Place a small 30A fuse as pictured, and solder it in. Make sure there is plenty of solder under the fuse. It takes a few seconds more than usual to heat up the PCB enough that the solder wets it nicely.

Now test again with the power meter, and if it works, assemble! :)
