OptiMate Lithium 8s Battery Chargers

An OptiMate Lithium 8s is a professional, 10-step battery charger and maintainer specifically designed for 25.6 V or 26.4 V LiFePO4 (lithium iron phosphate) batteries, often found in light aircraft, medical equipment, or RVs. It features an "Ampmatic" function that automatically adjusts charging current based on the battery's size and condition, a "TUNE" mode for stable power during diagnostics, and the ability to recover deeply discharged batteries. This automatic and safe charging program prevents overcharging and is suitable for long-term battery maintenance. Key features: * Target batteries: Designed for 8-cell LiFePO4 batteries with a nominal voltage of 25.6 V or 26.4 V. * Ampmatic technology: Automatically adjusts the charging current to match the battery's size and condition, providing more current for larger batteries and less for smaller ones. * Advanced 10-step program: Includes steps for charging, testing, and long-term maintenance, with safety features to prevent overcharging. * Low-volt recovery: Can save batteries that have been discharged as low as 0.5 V. * TUNE mode: Provides a stable (27.2 V) power source to support the battery during ECU programming, re-flashing, or software updates. * BMS wake up: A mode to safely reactivate a battery from sleep mode when its Battery Management System (BMS) is protecting it. * Maintenance mode: 24/7 smart maintenance prevents battery discharge from parasitic draws and keeps the battery at full charge. * Durability: The charger has a fully sealed, weatherproof case and is safe for long-term use.
