Why Choose Redway Lithium Batteries for Your RV?

Redway lithium iron phosphate (LiFePO4) batteries are the ideal power solution for your RV adventures. Here’s why:

1. More usable battery capacity: Redway lithium batteries allow you to use 100% of their capacity, regardless of the rate of discharge. This means you can run all your electronics and still have ample reserves, even when boondocking.
2. Zero maintenance: Unlike lead-acid batteries, Redway lithium batteries require no watering or other maintenance.
3. Constant power: Redway lithium batteries deliver consistent power without voltage sag, ensuring reliable performance for all your RV needs.
4. Drop-in replacement: Redway offers standard-sized BCI cases for their lithium batteries, making them easy to replace in your RV.
5. Longer life: Redway lithium batteries have up to 10 times longer life than lead-acid batteries, and they still provide 80% of their rated capacity after 2,000 cycles.
6. Partial State of Charge Tolerant: Partial charging does not affect the performance or lifespan of Redway lithium batteries, which is a leading cause of failure in lead-acid batteries.
7. Safety and reliability: Redway batteries are designed and engineered by a team with over 200 years of combined experience. The manufacturing facilities are ISO 9001:2015 certified, ensuring quality products that perform.
8. Environmental sustainability: Redway is committed to environmental sustainability and donates 1% of annual revenue to environmental nonprofits through 1% for the Planet.

Selecting the Right Battery Size for Your RV:

Redway offers 12V, 24V, 36V and 48V lithium batteries in various BCI standard sizes. The following are some popular RV batteries and their power capacities.

To determine the right battery size for your RV, you need to calculate your energy needs based on the power requirements of your appliances and devices. Redway’s Lithium Battery Selector Tool can assist you in finding the optimal battery for your specific application and usage.

Inverters for RVs:

Not every RV needs an inverter, and not every inverter needs to be specific to lithium batteries. In general, only AC-powered appliances and devices require an inverter. If you switch from lead-acid to lithium batteries, you won’t necessarily need a new inverter for your batteries. Redway lithium batteries are compatible with most inverters, ensuring a smooth transition.

Solar Panels and Charge Controllers:

If you’re considering adding solar power to your RV, you’ll need a charge controller to regulate the flow of energy between the solar array and the battery. There are two common types of charge controllers: pulse width modulation (PWM) and maximum power point tracking (MPPT). A PWM controller acts as an on/off switch, connecting and disconnecting the solar array from the battery. An MPPT controller monitors the voltage on both the solar array and the battery, maximizing the efficiency of the charging process. Before purchasing a charge controller, evaluate your power generation capabilities, anticipated power usage, and the environmental conditions in which you’ll need the power. This information will help you select the right charge controller for your RV solar setup.

Charging Lithium RV Batteries:

When charging LiFePO4 batteries, ensure you use a charger specifically designed for them. Avoid using chargers meant for other lithium-ion chemistries, as they may have higher voltage settings that can damage LiFePO4 batteries. If your LiFePO4 batteries are not fully discharged, they do not need to be charged after each use. These batteries are not affected by a partial state of charge (PSOC). You can charge them after each use or when they have been discharged up to 80% depth of discharge (DOD), leaving 20% state of charge (SOC). It’s recommended to store your lithium batteries at a 50% SOC to minimize irreversible capacity loss. If you are using a voltage-based fuel gauge designed for lead-acid batteries, replace it with one that measures current rather than voltage for accurate monitoring.
