Victron 20A 24V DC to 12V DC Isolated Battery-to-Battery Charger for Lead Acid or Lithium Batteries with Bluetooth
Victron 20A 24V DC to 12V DC battery-to-battery charger for lead acid or lithium batteries with Bluetooth and galvanic isolation
- Charges 12V batteries from 24V source using alternator, solar or DC input – suits dual voltage systems in vehicles and sites.
- Bluetooth app for monitoring, settings and adaptive charging to extend battery life.
- Galvanic isolation prevents current leakage in marine or mixed ground setups.
The Victron Orion-Tr Smart 24/12-20 isolated DC-DC charger provides 240W to charge 12V lead-acid or lithium batteries from a 24V source. Intelligent multi-stage charging includes bulk, absorption and float stages with engine detection for vehicles. Galvanic isolation up to 200V DC separates input, output and case.
Key Features
- Remote on/off and parallel capable for system expansion.
- Short circuit proof, high temperature protected with IP43 rating.
- Low standby draw under 1mA; suits smart alternators.
- LED indicators for charge stage and Bluetooth status.
Applications
Ideal for HGVs with 24V systems charging 12V auxiliaries, boats, off-grid sites and industrial dual-battery setups. Suggest installation via trusted partners for non-plug-and-play use; our UK experts can guide.
