Description

Blue Sea 9003e 350Amp Battery Switch

We recommend the use of several of these switches, as a stop gap measure, on parallel connected 12 and 24 Volt battery banks (Not rated for 48Volt banks), to enable the strings to be easily separated for equalization.

As always the design should be a single series string, but there are good economic arguments for keeping the already purchased batteries until they are used up. With routine equalization of the strings separately, much of the hard sulfation from the parallel bank design can be reversed.
