Product Overview
The Red Pole Energy RP12V90Ah-SL is a 12.8V 90Ah LiFePO4 starter battery for large SUVs, bakkies and vans requiring between 750A and 1000A cold cranking amps (CCA). Designed as a replacement option for compatible 12V lead-acid, AGM and EFB starter batteries, it combines high-discharge lithium cells with an automotive-grade battery management system (BMS).
Key Features
- 1000A maximum CCA for suitable high-demand 12V starting applications.
- Automotive-grade, high-discharge LiFePO4 cylindrical cells selected for transient-current, voltage and temperature tolerance.
- Automotive-grade BMS helps protect against over-charging, over-discharging, short circuits and improper charge voltages.
- IP66-rated enclosure helps protect the battery against dust and water ingress.
- PC/ABS casing with a VO rating is designed for impact resistance and high-temperature conditions.
- Maintenance-free design with supplier-stated self-discharge of less than 3% per month.
Applications
- Large SUVs, bakkies and vans requiring a 12V starter battery with 750A to 1000A CCA.
- Replacement for compatible 650S, 652, 654, 658 and 668 lead-acid battery formats.
- 12V vehicle starting applications where the required CCA, physical dimensions and terminal layout match.
Why Choose This Product?
This lithium starter battery is a practical option for suitable vehicles that need strong cranking performance in a compact, maintenance-free format. Its high-discharge LiFePO4 cells, BMS and IP66-rated enclosure support the demands placed on an automotive starter battery, while the 8.6kg weight may offer a lighter alternative to a comparable conventional starter battery.
Important Notes
- Left pole positive: when the terminals are furthest from you, the positive terminal is on the left.
- Confirm the vehicle's CCA requirement, battery dimensions, terminal orientation and terminal type before ordering.
- Use the Red Pole battery selection tool to confirm a suitable battery for your vehicle.
- Use within the specified 10V to 14.6V operating voltage range. Charging is specified from 0°C to 55°C; discharging is specified from -20°C to 70°C.
- Warranty: 3 years.
