Batteries in Series and Parallel Revisited
2 November 2016 | AdrianR
This is a popular historical Blog post created on one of our external Blogs. Revisited and transferred to the store Blog for information and Good Working Practice reasons. The post highlights important features that try to address bad practices, some of which became apparent within the mobile home and boating communities as requirements for additional electrical equipment increased. The introduction of The Boat Safety Scheme (BSS) Certificate again highlighted a common misunderstanding of battery connectivity, one of those topics we will touch on here.
One of the frequent questions to our help desk at Arc Components Limited is about batteries linked in Series and Parallel and the effect of voltage and amperage output. To help, we created a simple guide to show the cause and effect of batteries joined together to form battery banks.
A popular misconception, especially in the houseboat community, is the subject of joining batteries together in Parallel and using the size of the existing cable as an adequate size and format. They were often used as a pattern for sourcing additional cables to create a "Battery bank". The truth of joining batteries together in Parallel is that the batteries' Ampere Hour (Ah) is increased. Therefore, a new set of heavier-duty cables are usually required to avoid the wires potentially burning out.
Associated products for creating Battery Banks can be found in the "Automotive Terminals", "Automotive Cable", and the "Battery Shop Products" sections.

A technician could 'pull the guide up' for technicalities such as variables in cable length etc. We created the guide as a simple presentation to show the by-product of fitting additional batteries without preparation or consultation from a qualified tradesperson.
