These lithium batteries are perhaps one of the most important pieces of equipment we have on board because they, in concert with our solar system,  make our boat energy independent as well as more like a home by powering our electrical system.   

Our RB300 is a 12V, 300Ah lithium deep cycle battery. This Group 8D lithium iron phosphate (LiFePO4) battery is ready to replace your heavy lead-acid battery bank in your sailboat. It’s only 82 lbs for a true 300 Amp Hour lithium battery that provides 100% of its rated capacity. 

LiFePO4 batteries are lighter, take less space and last longer. While the up-front cost is higher than Gel, AGM or Lead-Acid the overall cost of ownership is lower over time because they require no maintenance and they have up to 10x longer life.

CBBF Series Marine Rated Battery Fuse

Suitable for main and auxiliary circuit protection (alternator outputs, starter motor inputs, and accessories) in demanding environments or tight space constraints

150 Amp rating; 58 Vdc

Marine-rated under SAE J1171 for ignition protection; use with CBBF-MBC mounting bar for installation

Balanced Twin Engine Charging

Balances Charging in Twin Engine Applications

Eliminates Alternator Chatter by Unifying Field Current

For Use with Max Charge Regulators Only

Works in Both 12V and 24V Applications

Includes Upgraded Regulator Power Wires and Fusing

Isolates Alternators and Regulators when only One Engine is Running

Can be Used with the Digital Duo Charge to charge a Second Battery

The Battery Protect disconnects the battery from non essential loads before it is completely discharged (which would damage the battery) or before it has insufficient power left to crank the engine

Maximum continuous load current 220 amp and Peak current (during 30 seconds) 600 amp

12/24-Volt auto ranging - The Battery Protect automatically detects system voltage

The Battery Protect can be set to engage / disengage at several different voltages, the seven segment display will indicate which setting has been chosen

To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 16-Volt respectively 32-Volt

Without proper voltage regulation, battery charging can be a slow process, or even worse, an ideal recipe for early battery failure.

​Balmar’s patented Max Charge and ARS-5 Voltage Regulators provide a dynamic method for monitoring battery condition and apply the correct level of alternator control (voltage and current) to ensure that your batteries are charged quickly and safely.

600A PowerBar with four 3/8" terminal studs

Reinforced polycarbonate base with tin plated pure electrical copper for maximum conductivity

4 mounting holes accept 1/4" screws

Max voltage: 300VAC/ 48VDC

Continuous Rating: 545A AC/ 600A DC

Use with Max Charge, ARS-5 and Duo Charge alternator regulators to monitor and react to dangerous over-temperature conditions at your alternator and/or batteries. When installed on Max Charge, ARS-5 and Duo Charge regulators, Battery Temperature Sensors assist in adjusting voltage based on ambient battery temperature. Battery sensor mounts on negative battery post.
