RB200

12V 200Ah
Deep Cycle Lithium Battery
Group 8D

This powerful lithium iron phosphate battery is ready to replace your heavy lead-acid battery bank in your sailboat, RV or solar energy system. The RB200 gives you the flexibility to replace several small, heavier lead-acid batteries in a single high-capacity unit.

Features

Lightweight

RELiON lithium batteries provide more power than lead-acid batteries and are typically half the weight. Boosting both performance and agility on the water.

Temperature Tolerant

Lithium batteries can handle a wide variety of conditions and are even 2.5x more efficient at low temperatures than lead-acid while being able to safely operate up to 149°F (65°C).

Fast Charging

RELiON lithium batteries charge much faster than traditional lead-acid batteries, and they’re packed with more usable energy and up to 10 times longer life so you’re always ready to go!

Long Life

RELiON lithium batteries provide up to 10 times longer life than lead-acid batteries, and they still provide 80% of the rated capacity after 3,500 cycles.

Maintenance Free

RELiON lithium batteries are maintenance-free – no watering, no corrosion. Low self-discharge means the batteries don’t lose capacity when they’re idle, assuring that you have the energy you need, every time you need it.

Constant Power

Full power available throughout discharge. Voltage does not drop like lead-acid.

Partial State of Charge Tolerant

Partial state of charge, known as PSOC, which is a killer of lead-acid batteries, does not affect performance or battery life of a lithium battery. Sometimes batteries don’t get fully charged, or they regularly operate in a partial state of charge. Either way, you can count on RELiON lithium batteries living a long and productive life.

More Usable Capacity

Lead-acid batteries are typically sized up to two times your energy needs to account for extended periods without sun and less usable energy with higher rates of discharge. Plus, you are typically cautioned to limit your use to 50% of the rated capacity, as using more can significantly reduce performance. Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge. And, you can use it all and still get substantially longer cycle life.
