I just got mine back from my reseller. I had the same problem after about two weeks, but shortly before it happened, there was a loud pop. When I checked the RBA, it looked like there might have been a short as the negative lead was glowing bright and was IMHO too close to the + post. The original one, SN#56xx had its MAH setting to 9 from the factory, and I changed it to 14.43 as prescribed by Escribe. The replacement, SN#12xxx came set to 14.43 out of the box. No problems, but only had it a few days.
