I'm interested as well. Mine shuts down after about five seconds. Currently working with Rockpals but it's an ebay purchase from a defunct seller and it's 18 months old. We'll see what they do, just emailed them. Otherwise, I'd love to know how to replace the BMS as that seems to be the problem...
Got it done and it works perfectly, thanks for the tips. Only problem is that I arced something while charging and now it won't charge on AC. Any input there would be equally great.
Brilliant and thanks. I'll let you know how it comes out. Really appreciate the information. Having a dead piece of expensive equipment is not exactly ideal.
