2. Trolling motor - Wikipedia

   en.wikipedia.org/wiki/Trolling_motor

   Diagram of a hand-controlled trolling motor Diagram of a foot-controlled trolling motor. Modern electric trolling motors are designed around a 12-volt, 24-volt or 36-volt brushed DC electric motor, to take advantage of the availability of 12-volt deep cycle batteries designed specifically for marine use. The motor itself is sealed inside a ...

3. 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.

4. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage , amperes, current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

5. Electric boat - Wikipedia

   en.wikipedia.org/wiki/Electric_boat

   Norway's first battery–electric ferry is MV Ampere, [22] [23] [24] with capacity for 120 cars and 12 trucks. As of November 2016 [update] , it has operated for 106,000 km. Its battery holds 1 MWh of energy, but the 9-minute charge time is sometimes not enough, and more battery capacity is to be installed.

7. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.

8. Electric vehicle battery - Wikipedia

   en.wikipedia.org/wiki/Electric_vehicle_battery

   When used properly, nickel–metal hydride batteries can have exceptionally long lives, as has been demonstrated in their use in hybrid cars and in the surviving first-generation NiMH Toyota RAV4 EVs that still operate well after 100,000 miles (160,000 km) and over a decade of service. Downsides include finicky charge cycles and poor ...

9. Nickel–metal hydride battery - Wikipedia

   en.wikipedia.org/wiki/Nickel–metal_hydride_battery

   A nickel–metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.
