   en.wikipedia.org/wiki/List_of_battery_sizes

   A common size for cells inside cordless tool battery packs. This size is also used in radio-controlled scale vehicle battery packs and some Soviet multimeters. 1 ⁄ 2-, 4 ⁄ 5 - and 5 ⁄ 4-sub-C sizes (differing in length) are also available. Soviet 332 type can be replaced with R10 (#4, 927, BF, U8) or 1.5 V elements from 3 V 2xLR10 packs ...

   A 36-volt nickel metal hydride (NiMH) battery pack, located under the load floor, powers the BAS and also stores electricity from regenerative braking. The regenerative brake charging and electric motor assist functions are shown to the driver via an analog gauge on the dashboard, and real-time fuel-economy feedback is accomplished via an "eco ...

5. Charge controller - Wikipedia

   en.wikipedia.org/wiki/Charge_controller

   By way of example, a 150 volt PV array connected to an MPPT charge controller can be used to charge a 24 or 48 volt battery. Higher array voltage means lower array current, so the savings in wiring costs can more than pay for the controller. [citation needed] Charge controllers may also monitor battery temperature to prevent overheating.

7. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.
