Redodo 12V 20Ah LiFePO4 Cranking Battery – 800CCA in a Compact Package
Brand: Redodo
The Redodo 12V 20Ah is a top-tier dedicated cranking battery for bass boats that need lightweight, reliable starting power in a compact, rugged package.
If you’re running a bass boat with a small to mid-sized outboard and want to shed serious weight, the Redodo 12V 20Ah is a game-changer. This lithium iron phosphate battery packs an impressive 800 CCA from a group U1 footprint, weighing just a fraction of a comparable lead-acid battery. The 40C discharge rate means it can dump massive current for those cold morning starts, and the luxury car-grade prismatic cells resist vibration far better than soft-pack alternatives—critical when you’re bouncing across chop.
Beyond starting power, the IP67 rating makes it completely dustproof and waterproof, so you can mount it in damp bilge compartments without worry. The proprietary sheet metal frame design prevents swelling, which is a common issue with lower-quality lithium batteries. While the 20Ah capacity limits its ability to run accessories for long periods, it’s an ideal dedicated cranking battery that pairs perfectly with a separate deep-cycle house battery.

Buyer’s Guide: What to Consider
Choosing the right cranking battery for your bass boat involves more than just picking the highest CCA number. Here are seven key factors to consider before making your purchase.
- Cold Cranking Amps (CCA): CCA measures a battery's ability to start an engine in cold temperatures. For bass boats, look for at least 750-800 CCA for small to midsize outboards, and 1000+ CCA for larger motors. Higher CCA ensures reliable starts even on chilly mornings.
- Battery Type: LiFePO4 vs. AGM vs. Flooded: Lithium iron phosphate (LiFePO4) batteries are lightweight, have long cycle lives, and offer high CCA, but cost more upfront. AGM batteries are sealed, vibration-resistant, and more affordable, but heavier. Flooded batteries are cheapest but require maintenance and are less durable.
- Dual-Purpose vs. Dedicated Cranking: A dual-purpose battery combines cranking power with deep-cycle capacity, letting you start the engine and run accessories from one unit. A dedicated cranking battery is lighter and cheaper but requires a separate house battery for trolling motors and electronics.
- Capacity (Ah) and Reserve Capacity: Amp-hour (Ah) rating tells you how much energy the battery can store. For cranking-only, 20-50Ah is enough. For dual-purpose, 100Ah or more lets you run accessories for hours. Reserve capacity (minutes) indicates how long the battery can run essential loads if the alternator fails.
- Weight and Size: Lithium batteries are typically 50-70% lighter than AGM or flooded batteries of similar capacity. This reduces your boat's overall weight, improving fuel economy and acceleration. Make sure the battery fits your designated tray or compartment (Group 24, 31, U1, etc.).
- Durability and Waterproofing: Marine environments are tough on batteries. Look for IP ratings (e.g., IP67 for dust and water resistance), vibration resistance, and corrosion-resistant terminals. A robust BMS (Battery Management System) protects against overcharging, over-discharging, and short circuits.
- Emergency Reserve and Safety Features: Some lithium batteries include an emergency reserve that automatically preserves about 15% of capacity to ensure you can restart the engine. This feature can prevent stranding. Also check for low-temperature protection if you fish in cold climates.
Conclusion
Choosing the best cranking battery for your bass boat comes down to your specific needs and budget. If you prioritize weight savings and high starting power, lithium options like the Redodo 12V 20Ah or Litime 100Ah Group24 offer excellent performance in compact packages. For those who want a single battery to handle both cranking and deep-cycle duties, the Litime 165Ah or Interstate 31M-AGM-A are solid choices. And if you fish in freezing conditions, the heated Norsk Lithium 180AH is a smart investment.
No matter which battery you choose, always ensure it meets your outboard’s CCA requirements and fits your battery tray. Pairing a dedicated cranking battery with a separate deep-cycle house battery is often the most reliable setup for serious bass anglers. We hope this guide helps you power your next fishing trip with confidence—tight lines!
