Marine Battery Technologies
- Lithium (LiFePO4): Lightweight, supports 3000+ charge cycles, flat discharge voltage curve, and built-in Bluetooth monitoring.
- AGM (Absorbed Glass Mat): Spill-proof, maintenance-free, high vibration resistance, and excellent dual-purpose starting/deep-cycle power.
- Smart Chargers: Multi-bank onboard chargers optimized for lithium and lead-acid battery chemistries.
Frequently Asked Questions
Q: What are the main benefits of Lithium LiFePO4 batteries over traditional AGM batteries?
A: Lithium batteries are roughly 50% lighter, can be discharged up to 100% without damage (compared to 50% for AGM), maintain full power output until completely discharged, and last 5-10 times longer (up to 10 years of regular use).
Q: Can I charge a lithium marine battery with my existing lead-acid charger?
A: Only if your charger has a dedicated Lithium charging profile. Lithium batteries require a specific constant-current/constant-voltage profile and do not like the desulfation or float stages used for lead-acid cells.
Q: What is a dual-purpose marine battery?
A: A dual-purpose battery is designed to provide both the high cold-cranking amps (CCA) needed to start an outboard motor, and the deep-cycle capacity needed to run trolling motors, house lights, and electronics.
