Mobile battery modules for high power applications

A mobile battery module comprising:

• a case having a chamber therein, wherein an engagement element is disposed on an inner surface of the case;
• a removable first block that engages the engagement element and which includes a first pair of opposing sidewalls, wherein a first end cap extends from one of the first pair of opposing sidewalls and a second end cap extends from the other of the first pair of opposing sidewalls towards the first end cap such that the first and second end caps are arranged to cooperatively hold a first battery there between;
• a removable second block that engages the engagement element and which includes a second pair of opposing sidewalls, wherein a third end cap extends from one of the second pair of opposing sidewalls and a fourth end cap extends from the other of the second pair of opposing sidewalls towards the third end cap such that the third and fourth end caps are arranged to cooperatively hold a second battery there between;
• wherein the first battery extends along an axis that intersects first and second battery ends of the first battery and has a battery sidewall extending continuously between the first and second battery ends, wherein a battery terminal is disposed on at least one of the first or second battery ends and at least one pressure relief vent is disposed on the battery sidewall to selectively vent pressure from the first battery, and
• wherein at least one of the first or second end caps extends from its sidewall by a distance sufficient to extend beyond the at least one pressure relief vent.
