Product Details
RELiON RB35 12V 35Ah LiFePO4 Deep Cycle Battery
RELiON RB35 12V 35Ah LiFePO4 Deep Cycle Battery (Model: RB35) – High-Performance Power Solution for Marine, RV, Solar, Industrial, and Recreational Applications
The RELiON RB35 12V 35Ah LiFePO4 Deep Cycle Battery (Part No: RB35) is a lightweight powerhouse delivering 35Ah of reliable LiFePO4 power at 12.8V (448Wh), offering twice the usable capacity of lead-acid batteries at half the weight (just 9.9 lbs), with over 3,500 cycles at 80% DoD. Featuring an integrated BMS for safety and efficiency, IP66 waterproof enclosure for harsh environments, and M8 terminals for easy integration, it supports 35A continuous discharge (70A peak for 7.5s), making it ideal for high-amp electronics, outdoor recreational use, fishing electronics, robotics, solar lighting, remote power, or as a direct replacement for UB12350 SLA batteries in maintenance-free applications.
Key Features:
- High-Capacity Design: 35Ah at 12.8V (448Wh) for reliable performance in 12V systems, perfect for lighter industrial and recreational loads.
- Integrated BMS: Protects against overcharge, over-discharge, short-circuit, and thermal issues; ensures cell balancing for optimal longevity.
- High Discharge Capability: 35A continuous / 70A peak (7.5s) for powering devices up to 448W or high-draw electronics.
- Extended Cycle Life: 3,500+ cycles at 80% DoD, with <3% monthly self-discharge for reliable standby power.
- Versatile Compatibility: Drop-in replacement for UB12350 SLA batteries; supports series/parallel configurations (up to 3S); compatible with most 12V chargers.
