Enjoy Home Comforts on the Road When You Leave the Power Stress Behind

@La Cruiser

It's also much more vibration-resistant and water, dust, and flame - resistant. What a tank! Should make light work of powering the fridge, lights, water pump, and Starlink on our adventures!

@3DayRV

This battery is significantly smaller than the Core series batteries. Uh, it weighs in about 52 lbs. So that is a big time plus. It's not terribly heavy. I do like the metal case that it comes with, and it does have little mounting lugs on the side so you can screw it down to a floor, cabinet, whatever, so it doesn't take off.

@There's A Trick for That

They've programmed the BMS correctly so that this will give you a whole bunch of power, as it's designed to do way more than a standard 100Ah battery. But as soon as you exceed what it's designed to do, it is very quick to protect itself, which is a very good safety thing to see implemented.

@VoltAmpereLux

At the highest power setting of the hairdryer, it draws 2400 watts. That corresponds to 190A (Pro S1 120). I was able to do that for about one to two minutes before the battery went into overload protection and essentially shut off the output. So I have a bit of power reserve. 2000 watts continuous power is possible...If I'm briefly running a kettle or whatever, I have some power reserves available.

FAQ

Does the solid state battery contain 100% solid electrolytes?

No. Currently, there are no 100% solid-state batteries available on the market. Our semi-solid battery cells reduce liquid electrolyte by approximately 70% compared to conventional lithium-ion batteries. This helps to provide a safer, more stable, and higher-performing power source for your full-time off-grid living.

What is the maximum output of this lithium battery?

Renogy Pro S1 12V 120Ah Battery can discharge at 150A (1.25C), considering 120Ah capacity. This means one single battery is able to output 1920W continuously and 2112W peak power for 60s. It can work with a 1800W inverter to power esential appliances through your tough adventures.

Do I need to use a BT module to monitor the status on my phone with Renogy smart app?

No. The battery has built-in Bluetooth, so you can track status in real time through the Renogy app. It also includes CAN ports for simple communication between devices.

How to recharge my solid state batteries?

You can charge them with solar, a DC-DC charger, or an AC-DC charger. We recommend using a controller or charger designed for LiFePO4 batteries.

What is the life expectancy of this battery?

About 6000 cycles at 80% depth of discharge, depending on temperature and storage conditions.

Please explain the multi-stage discharge overcurrent protection (165A/1min → 240A/30s → 360A/200ms). Why not use a single hard cutoff?

Thisgraded responsebalances protection with usability:
● 165A/1min: Allows for sustained overloads (e.g., inverter surge) without nuisance trips.
● 240A/30s: Permits brief motor starts (e.g., RV AC compressors).
● 360A/200ms: Hard cutoff for dead shorts (1000A/110µs).

Is this battery waterproof?

Yes, the battery is IP67-rated, which means it can be submerged in water up to 1 meter / 39.37 inch deep for up to 30 minutes.
