'allows' for 2 batteries. cnpad actually didn't copy paste for once and did an article on this: aPad iRobot gets new board MD01-V6.0 ? cnPad.info ? aPad iRobot MoonseBattery life is better. It performs better. It has better power filtering. Overall more reliable. Shipping firmware still a piece of crapI can bet that Miss Wang on Aliexpress has some, but you have to ask her which listing it is. She's someone who I think is getting her batches directly from the factory. JTShop can get some if you ask for them, and I think he's supplied by the Hiapad related factory as well. Merimobiles has purchased from Moonse in the past, but has claimed that they had bought from Utopia at one point. Who knows from where they are getting their stuff now. TabletstoreUK seems to have the new batch 3s. Key is ASK. I only maintain contact with chip3c, who has ties with hiapad and Utopia Shenzhen. At the end of the day, he only takes care of what's coming out of his own factory. It's a mess out there. If you look for the Apad tablet in Alibaba China wholesale listings, there are probably over 50 listings of wholesale distributors from 500-700RMB. It must be a pretty easy device to clone.
