Key Features

4 Times Longer Lifespan
Offering a lifespan of 2000 cycles (roughly 5-year lifespan at daily use) at 80% DOD, Renogy 12V 170Ah LiFePO4 battery could last 4X longer than conventional lead-acid batteries.

Powerful Output
Renogy 12V 170Ah LiFePO4 battery provides a maximum of 2176 Wh power output, which is 2 to 3 times more powerful comparing to most lead-acid batteries in the same size. More power, less battery-draining anxiety.

High Discharging Performance
The battery provides a maximum of 125Ah continuous discharge current to power most home appliances. The superior lithium-iron-phosphate technology ensures stable battery capacity and performance even under extreme temperatures from -4℉ (-20℃) to 140℉ (60℃).

Safe and Reliable
The built-in Battery Management System (BMS) provides over-charge/discharge, over-current, high temperatures, and short-circuiting protection. The fully-sealed housing prevents acid leakage and corrosion and ensures simple maintenance.

50% Lighter
Twice the power of lead-acid batteries at half the weight. This LiFePO4 battery is smaller, lighter, and at the same time delivers more power. The reduced weight makes it easy to carry and install.

Warranty Information

Material and workmanship warranty 5-year
1.Can these batteries be hooked up in parallel and in series ?
You can connect these Renogy 12V 170Ah Lithium batteries in parallel to expand power supply capacity, BUT you can NOT wire them in series. When wiring in parallel, we recommend using identical batteries, same type (Lithium-Iron Phosphate), same capacity (Ah), same voltage (V), same brand (Renogy).
2. Can this battery be combined with a 12V lead acid battery bank ?
We highly recommend NOT stringing lithium batteries to any lead acid batteries. When combining batteries, it's recommended to connect batteries with the same type (Lithium-Iron Phosphate), same capacity (Ah), same voltage (V) from the same brand (Renogy).
3. Does this battery come with terminal bolts? What's the size of the bolt ?
Yes, the battery comes with a pair of M12x1.75x16mm bolts. But please be aware that the battery's M12 terminals are thicker and will not work with any of our battery cable offerings, they require 1/2"" ring terminals for proper connectivity.
4. Are these batteries optimal for a marine environment? On a live aboard sailboat with solar and wind?
These sealed lithium-iron phosphate batteries are perfect for the marine environment. You can use them on your boat or kayak. Additionally, they can be run on various off-grid, emergency, and energy storage systems, including RVs, vans, cabins, solar/wind energy systems, UPS battery backups, telecommunication systems, medical equipment, and more.
5. What's the operating temperature of this 170Ah battery? Can I charge it below freezing ?
The operating temperature for discharging is -4℉~140℉ / -20℃~60℃. The operating temperature range for charging is 32℉~113℉ / 0℃~45℃. For optimal performance, we recommend using this battery at 73.4 ± 9℉ / 23 ± 5℃.
6. Can I use any 12V battery charger to charge this battery or does it have to be a specialized lithium charger ?
You need to use a battery charger compatible with Lithium-Iron Phosphate deep cycle batteries to charge this battery, or it will be damaged. Renogy's 12V DC-DC and AC-DC battery chargers all support charging Lithium batteries, you can visit our website for more information.

170ah Lithium Battery

George Bishop on Nov 9th 2022

This is my second battery. I have been using the same model for over a year switching it between my boat and camper. This battery has changed our cruising and camping life by holding more energy than 3 of my old lead acid batteries at a fraction of the weight. Also, with it's ability to take maximum alternator output, it reduces my charge time significantly. So happy with it that I bought a second one!

Batteries 170AH

Michel Galarneau on Jan 24th 2022

Just recently ordered 5 Batteries 170AH and installed them in Paralell as a pre-test for my RV when Winter goes away. So far so good, I tested with a Renogy 2000W inverter and a Renogy Monitor. After 8 hours running with a 1500W heat gun it still runs great! I see many ads of Batteries that are supposed to be cheaper or better and so far I am pleased to buy from Renogy. It's the best bang for the buck so far... Only complaint is the size of the post which needs a 1/2" connector!

Great deal

Dave on Sep 30th 2021

Got two of these when they were on sale, excellent deal. Arrived alive with a good charge, only drawback is the mega bolts on this, it would be nice if they through in a few appropriate lugs. No low voltage sensor, so ensure your storage conditions keep them happy or you have an appropriate temp sensor setup with your charge controller.
