A battery comprising:

• a plurality of battery modules arranged in a row, each battery module comprising a plurality of cells and a housing enclosing the plurality of cells;
• and
• a supply coolant conduit and a drain coolant conduit, each adjoining and extending along at least part of the row of battery modules, the supply coolant conduit being configured to supply coolant to multiple ones of the battery modules and the drain coolant conduit being configured to drain coolant from multiple ones of the battery modules,
• wherein the supply coolant conduit comprises:
• a plurality of supply coolant conduit portions, each supply coolant conduit portion adjoining a respective one of the battery modules;
• and
• couplers, each coupler connecting pairs of adjacent supply coolant conduit portions;
• and
• wherein the drain coolant conduit comprises:
• a plurality of drain coolant conduit portions, each drain coolant conduit portion adjoining a respective one of the battery modules;
• and
• couplers, each coupler connecting pairs of adjacent drain coolant conduit portions;
• wherein, for each battery module in the plurality of battery modules, a supply coolant conduit portion adjoins a face of the battery module and a drain coolant conduit portion adjoins the face of the battery module, the supply coolant conduit portion being configured to supply coolant to the battery module and the drain coolant conduit portion being configured to drain coolant from the battery module;
• and
• the plurality of cells in each battery module are configured to be directly contacted by coolant supplied to the battery module.
