Installing a secondary battery in a location separate from the original bank creates significant electrical and maintenance challenges. Jeff Cote of Pacific Yacht Systems advises against splitting battery banks because high-output chargers with temperature sensors cannot accurately monitor thermal runaway across two distinct physical locations.2:05 If batteries are separated, they often discharge and charge unevenly, leading to premature failure of individual units.4:17 Because battery banks must be replaced as a set to ensure longevity, uneven wear significantly increases long-term replacement costs.4:06 When space constraints prevent housing all batteries together, a battery source selector switch—such as an off-one-two-both configuration—allows for manual isolation or parallel connection.3:30 However, this setup requires careful management to avoid damaging the alternator by switching to off while charging.1:44 The most reliable solution remains finding a single, consolidated location for the entire battery bank to ensure uniform performance and simplified maintenance.3:09
