3×70 A charge splitter – code: 14.922.53 – Osculati

Osculati 3×70 A charge splitter (code 14.922.53)

The charge splitter Osculati is a component designed for managing charging in systems with multiple batteries on board. This model 3×70 A allows to to charge multiple batteries simultaneously starting from a single charging source (for example, an alternator), giving preference to the battery with the lowest charge. This way, a more orderly and functional charge distribution is achieved, useful when you want to keep services separate (engine battery, services, any dedicated loads) without giving up the convenience of centralized charging.

A key aspect of the splitter is the electrical separation between the batteries: each battery remains isolated from the others, thus preventing the energy from the more charged battery from flowing into the less charged one. This operating logic helps maintain a more stable system setup and reduces interference between battery banks with different charge levels.

Features and construction details

Charge distribution on multiple batteries

The splitter is designed to manage 3 batteries and a charging source (1 alternator). The maximum current supplied for each battery is 70 A. This configuration is typical of systems where a clear separation between battery lines is desired, while ensuring simultaneous and automatic charging.

Electrical separation between banks

The separation function is central: the device electrically isolates each battery to prevent unwanted energy transfers between accumulators with different charge states. In practice, each battery is managed as a dedicated branch, with the goal of preventing one battery from “discharging” into another.

Aluminum housing with fins

The splitter is made with aluminum housing and features a wide finning designed for to effectively dissipate heat. In nautical and electrical systems, thermal management is an important element: a finned structure promotes the dissipation of heat generated during operation, contributing to a neater installation suitable for technical compartments.

Typical applications in nautical and plant engineering

This charge splitter is recommended when the system includes multiple batteries with different functions and a more rational charging management is desired. It is a common solution on boats and technical vehicles where circuit separation is a practical requirement to organize loads and simplify maintenance.

Examples of use

• Systems with engine battery and service batteries: simultaneous charging while keeping the banks separate.
• Systems with multiple service lines: management of batteries dedicated to different loads, avoiding energy exchanges between banks.
• Refits and maintenance: updating the charging system when adding batteries or reorganizing circuits.

Operational advantages

Simultaneous charging with priority logic

The splitter allows charging multiple batteries at the same time and, according to the product specifications, prioritizes the most discharged battery. This approach is useful to keep the overall state of charge more balanced, especially when onboard loads are uneven and some batteries are stressed more than others.

Neater system and more “independent” batteries”

The electrical separation among the banks helps prevent one battery from affecting another. In a well-organized system, this results in clearer management: each battery remains associated with its own circuit, reducing situations where a battery with a higher charge unintentionally powers another more discharged battery.

Structure designed for dissipation

The aluminum housing with finned is an important construction detail for installation in technical environments. Effective heat dissipation is a practical element in engine compartments or electrical panels, where ventilation may be limited and component arrangement must remain compact and accessible.

Usage and installation notes

The charge splitter is a component of the electrical system: for correct installation, it is advisable to operate with onboard system criteria, respecting good wiring practices and proper identification of battery circuits. In case of doubts about the diagram, cable sections, or protections, it is appropriate to refer to the system documentation and the manufacturer's instructions.

Practical indications (general)

• Positioning: install in an accessible point for inspection and maintenance, taking into account the thermal dissipation of the finned housing.
• Connection order: keep clear the correspondence between each output and the dedicated battery, labeling cables if necessary.
• Separation of banks: use the isolation function to keep circuits distinct (engine/services/dedicated loads) according to the system logic.
