100% Safety & Reliable
Our RLB 12V, 300Ah Lithium Deep Cycle Lithium Iron Phosphate (LiFePO4) battery is ready to replace the heavy-duty lead-acid battery pack in your sailboat, RV, or solar system. The true 300 Amp Hour LiFePO4 battery is only 60 pounds and provides 100% of its rated capacity. Gives you the flexibility to replace multiple smaller, heavier lead-acid batteries in a single high-capacity unit. LiFePO4 batteries are lighter in weight, take up less space, and last longer. Although the upfront cost is higher than Gel, AGM, or Lead-Acid, the total cost of ownership decreases over time because they are maintenance-free and last up to 10 times longer. The RLB 300Ah lithium batteries provide highly reliable performance for RVs, campers, sailboats, and battery-operated solar systems in any climate or condition.

Q. Will the IPS-M3600LFP work in my RV?
A: YES! The RB300 is a reliable and effective alternative to lead-acid batteries in an RV, travel trailer, or camper. The weight and size of the lead-acid battery pack are sometimes not feasible in smaller RVs. Also, lithium batteries require no maintenance, no ventilation, and can be mounted in any location. Typical lead-acid RV batteries only allow you to use about 50% of their rated capacity, while lithium batteries are ideal for taking on-the-go wilderness camping on the road. The RB300 has a highly sustainable voltage level that provides 99% of the available capacity, allowing you to have more free time at home.
Q. Can the IPS-M3600LFP be connected in series or parallel?
A: Yes. The RB300 can be connected in series or parallel. Difference between parallel and series: parallel connection involves connecting 2 or more batteries to increase the capacity of the battery pack. In this case, the positive extremes of all the cells are connected and the negative extremes are connected until the desired capacity is reached. A series connection involves connecting 2 or more batteries to increase the voltage of the battery system. The positive terminal of one battery is connected to the negative terminal of the other battery until the desired voltage is obtained. For example, if 2 x 12V batteries are connected in series, the battery system will be 24V.
