Yes it has been highlighted here before, just to let fellow members here to know its just around the corner again this year to grab your goodies. 
Personally, i’m thinking of upgrading my battery pack, will have to wait until 11.11 to see if its really cheap & worth it. What do you have in mind that worth buying then share it here.
Some article worth reading like this & this & this, Happy Shopping, Guys 
i’ve seen few dads here build for their kids, why DIY when you can buy it dirt cheap, found this & this 
Though you won’t get it at this price 
Most failures i’ve seen is the battery, just replace that single faulty 18650 & it’ll work again.
It’ll be a great Christmas gift for your sons, daughters, nephews, nieces too or may be even one for yourself 
Still haven’t made up my mind yet, looks like they are indeed few great deals there
This one seems cheap, rest of the deals here
Donno if i wanna try the boosted board battery, rest of the deals here
Don’t buy any of them
The first have been tested and seemed ok if I remember. The rest are probs trash
There are many good feedbacks, you guys are getting me worried, to order or not to order
It might have the capacity but not high discharge
This guy totally recommends it, is it worth to take the risk 
Could be a fake review. Most sites are full of them

Although honestly for like $50 maybe try it for science as a 12s1p and see how it goes. If it’s good but more
