A product that was designed at a company I worked for until a year ago used chunky lithium ion batteries weighing several kg. These were custom made by SAFT, and each cell had protection (thermal, charge balancing, voltage, all led to the outside world). In addition they were enclosed in diecast hermetically sealed enclosures with expansion room (they swell as they charge), with Fischer hermetically sealed connectors. Two such in the product. These were removed from the product for charging using a custom and highly developed charger.
The whole battery, enclosures, monitoring and charging system cost several k.
