Marine Batteries for Boats and Electronics

Lithium marine batteries power various devices and equipment on boats, including trolling motors, fish finders, GPS systems, and more. Eco Tree’s LiFePO4 deep-cycle battery is designed to be discharged and recharged multiple times without damage to the battery. And LiFePO4 batteries have a longer lifespan than traditional lead-acid batteries.

Benefits of LiFePO4 Marine Batteries

Lithium iron phosphate deep-cycle batteries provide an extended cycle life and ultra-low self-discharge rate. Other benefits include:

  • Long life saves money
  • 10 x faster-charging cycles than lead acid batteries or AGM batteries
  • Reliable, high-performance cells for improved power capacity
  • Less weight, typically half of a lead acid battery, so easier to carry and transport
  • Constant voltage output over long periods
  • Built-in Battery Management System (BMS)
  • Zero maintenance
  • Low carbon footprint: Non-liquid, non-corrosive, non-toxic
  • UN38.3 IP56, 93/66/EEC, UL94-Vo, IMDG safety rating
  • Easy install – drop-in replacement

How long do lithium marine batteries last?

The lifespan of a lithium marine battery depends on several factors, such as frequency of use, how well it is maintained, and the conditions under which it is stored. However, a marine battery should last for several years with proper care.

Do lithium boat batteries require a special charger?

No, you can charge lithium boat batteries with a standard marine battery charger. Or direct engine charging and split charging using a fixed voltage alternator. However, consult your battery’s manufacturer for specific charging instructions, as some lithium batteries require a slower charge rate than others.
