Thank you very much for the specs and the link. I’ve ordered one.
Did you really replaced the battery with a new? Then, why don’t you can answer where to buy a new? Or do you just dismounted it, to show how it can work?
I found so many 3.7 V 350 mAH LiPo batteries with a bit different dimensions. I wan’t to buy the right, before try to change it.
Can you please specify the dimensions of the battery? Or, if possible, a direct link to order one (eBay, Amazon, some shop witch delivery to germany)?
