Lithionics Marine Batteries provide power for RVs, trolling motors, Lithionics Marine Batteriesmarine accessories and virtually any engine-starting needs. The Lithium Marine Battery corrosion-resistant high quality brass terminals provide reliable starting power in all weather conditions. Its rugged, military-grade construction features robust, yet shockingly offers superior vibration resistance.

The Lithionics battery systems that we offer are uniquely configured for Marine, RV and off-grid applications through the utilization of an external dual battery monitoring system (BMS). This industry unique BMS provides for two positive terminals on the battery and a single negative terminal. One positive is used to support loads off the battery while the second is used to support charging sources to the battery. This makes the batteries significantly different than other competitive devices by allowing excessive charging sources to be disconnected without losing power to the critical loads off the battery when safety levels are exceeded.

Additionally the BMS current handling is very high allowing for loads to be handled that are typically found in our customers applications.Lower cost two terminal batteries are unlikely to meet the application needs.

Safety is paramount with Lithionics. All of their battery cells utilize the STOBA technology providing maximum safety, protection and increased cycle life. We encourage you to learn more about STOBA and its value to you as a consumer by watching this 3 min video. It's time worth spending.

How does storing energy in a lithium battery help you:

  • Faster Charging (1-2 hrs)
  • 75% Less weight
  • Reduced Generator Use
  • Longer off-season storage time-ideal for boats
  • 98% round-trip charge efficiency (compared to 36% for lead-acid batteries)
  • Replaces up to SIX Lead-Acid Batteries with ONE Li3 Battery!
  • Retains 75% Power-Energy Levels Up to Two Years
  • Always Doubles the Amount of Energy MINIMUM
  • Save Hundreds of Pounds
  • Longer Overall Life (5x)


  1. All Charging sources require a lithium profile matching the battery specifications or damage may occur.
  2. Connecting lithium batteries to other battery chemistries (such as AGM) requires a battery to battery charger only with the appropriate battery profiles used.
