Braibar – Hybrid Power Engine and 2v Cells

Narrow boat batteries fitted to the Braibar canal boat. Engine & 2V cells
With Braibar we worked with them to help with the technical areas of battery power required and space for the battery. The power required for these Narrow Boat Batteries was hidden away under the storage area and fitted with an automatic topping and gas venting system for convenience and safety. The 48v battery utilises 24 off 2v cells with a capacity of 875 A/h. This battery enables the operator to cruise on Electric power and when cruising with engine power the electric motor recharges the battery. The battery also has the facility to be charged overnight by shore power.

The Chelonian – Narrow Boat Batteries - Hybrid Power – Engine & 2v Cells

The chelonian using narrow boat Batteries
The Chelonian was installed with a hybrid system and we installed a 48v 2v cell 450A/h battery under the steps. The battery was installed complete with auto topping and a gas venting system to comply with health and safety. The work we have carried out with Hybrid Narrow Boats have proved to be very successful and beyond the expectations of the owners. If you would like more information regarding your Narrow Boat and the options available to you for electric power please contact us and our technicians will be glad to talk to you.

The Peruvian Skies – Engine Powered & GEL Mono Bloc Powered Domestic Electrics

A canal boat fitted with narrow boat batteries
With the Peruvian Skies Narrow Boat the owner had us replace the 12v blocks with 2v traction cells to maintain his 24v domestic electrical system. The 2v cells installed with automatic topping up and gas venting system are 540 A/h. This has given the owner the solution to his domestic power prematurely exhausting allowing more time to enjoy the Narrow Boat.

Using 2 Volt Deep Cycle Cells for Narrow Boat Batteries

2-Volt-Deep-Cycle-CellsWith the vast range of 2v cells in height, width Ecobat can accommodate the supply of 2v cells in the capacity of your need for your Narrow Boat application. The 2v deep cycle cell has a distinct advantage over what is termed as a Leisure Battery. The Leisure Battery has a Discharge value of no more than 50% and the life expectancy of 2 – 4 years with exception. Whereas the 2v deep cycle cell is designed to be discharged to 80% and have a life expectancy of 2 – 3 times of that of leisure. Example: - 100A/H Leisure battery has 50 useable amps and as opposed to 100A/H 2v deep cycle that has 80 useable amps. The 2v deep cycle for electric propulsion gives far wider range of capacities than can be gained using leisure batteries FROM 84–1860 Ah.

6V to 12V Monoblocs as Narrow Boat Batteries

Where space does not allow for 2V cells, Mono Blocs can be your solution and at Ecobat we will be able to advise for your requirements. 6V – 12V cyclic Mono Bloc’s flooded are predominantly used for cyclic use domestic electrics and electric propulsion for the smaller craft. 6V – 12V cyclic GEL is used where restrictions within enclosed areas where the build-up of gas would be a hazard. These Mono Blocs are available with capacities FROM 35-370 Ah

50Hz and High Frequency Chargers

Shores based chargers or on-board chargers are available, from 50Hz to Low Energy Consumption High Frequency taking energy saving to new levels, and with a range to suit all applications.
