Our school is planning to buy a few dozen mBot.
The only version with good availability here (Switzerland/Germany) seems to be SKU P1050015 (https://b2b.makeblock.com/products/explorer-kits.html), usually called “mBot-S”. This version does not include a battery holder for a LiPo battery.
Does the official battery (https://b2b.makeblock.com/products/mbot-li-polymer-battery.html) include the battery shell?
Is the battery shell sold separately (and if so, what’s the SKU)?
