Notes:

Has small cells that fit into their own monitored 'block', which in turn is built into modules and batteries. All cells are therefore more or less the same dimensions but have different capacities and abilities. They give the maximum discharge rate in watts per kilogram - I've worked backward from this to the amp rating. Sonata cell specs give no discharge parameters.

(See cell information for this manufacturer.)
