How to Choose the Right Product

What accessories do I need for my power system?

For a complete dual battery system, you typically need a DC-DC battery charger (such as the REDARC BCDC series), a battery management system (BMS), wiring harness, fuses, and cable terminals. For advanced monitoring, the REDARC Manager30 with RedVision display provides full system visibility including battery state, solar input, and AC charging status.

Which accessories are commonly used with batteries and inverters?

Common accessories include Anderson plugs, ANL fuse holders, battery isolators, shunt resistors for current monitoring, and DC wiring kits. REDARC BCDC chargers are frequently paired with ANTPAK LiFePO4 batteries (100Ah–400Ah) and solar panels for a complete off-grid power solution.

Are these accessories suitable for automotive and off-grid use?

Yes. REDARC BCDC chargers (25A–100A) are specifically engineered for in-vehicle dual battery charging, supporting 12V and 24V systems. They are compatible with 4WD, caravan, marine, and off-grid applications, and include MPPT solar input for simultaneous charging from alternator and solar panels.

How do I choose the right BCDC charger for my setup?

Select based on your battery capacity and charging speed requirement:

  • BCDC1225 (25A) suitable for batteries up to 120Ah, ideal for smaller setups or space-limited installations.
  • BCDC1240 Core (40A) recommended for 120Ah–200Ah lithium batteries with faster charging cycles.
  • BCDC Alpha50 (50A) for 200Ah+ batteries or dual battery banks requiring higher charge current.
  • BCDC Alpha100 (100A) designed for large lithium systems (300Ah–400Ah) and heavy-duty 4WD builds.
Do I need professional installation for these accessories?

REDARC BCDC chargers and Manager30 systems involve high-current 12V/24V wiring and must be installed by a qualified auto electrician to ensure safe operation and maintain warranty validity. Incorrect wiring can damage the unit and void the manufacturer's warranty. Camperise stocks complete wiring kits to simplify the installation process.
