5.7 out of 10

At 12.8 V and 120 Ah it stores 1,536 Wh, so it scores 5 on capacity.

Its 1,536 Wh in 29.5 lb works out to 52.1 Wh per pound, so it scores 6 on efficiency.

Renogy's manual rates the BMS for 150 A continuous, 1.25C on 120 Ah, with 350 A for 30 seconds, so it scores 5 on operating range.

Renogy rates it for 6,000 cycles at 80 percent depth of discharge, retaining 80 percent of capacity, one rung down for the shallower depth, so it scores 8 on lifespan.

It carries an 85 W self-heating pad, built-in Bluetooth, two CAN ports, an IP67 case and 4S4P wiring, every point on the scale, so it scores 10 on features.

No certifier directory (Intertek, UL Product iQ, CSA, SGS, TÜV or the CEC lists) lists this model, so it scores 2 on verification.

Renogy's current warranty document lists it under a 7-year prorated material and workmanship warranty, so it scores 6 on warranty and support.

Every feature point, semi-solid on Renogy's word

The RBT12120LFP-SBH is Renogy's Pro S1 12.8 V 120 Ah lithium iron phosphate battery, built on cells Renogy sells as semi-solid-state.

Verdict

It suits a buyer building a cold-weather van or RV bank of up to 48 V around Renogy's CAN-linked chargers, who accepts that the semi-solid-state cell claim rests on Renogy's own description.

Strengths

  • 150 A continuous and 350 A for 30 seconds
  • Up to 4 in series and 4 in parallel48 V and 24.576 kWh at most
  • Two RJ45 CAN ports plus built-in Bluetooth
  • 85 W heaterabout 2 hours from -4 °F to 32 °F by the manual
  • 6,000 cycles at 80 percent depth of discharge
  • Four fix brackets and screws in the box

Drawbacks

  • Semi-solid-state is Renogy's own descriptionit publishes only "about 70 percent less liquid electrolyte"
  • Heater runs only while charge current stays above 10 A
  • Renogy's warranty document calls the 7 years proratedthe product page says only 7 years
  • CAN cables and termination resistors sold separately
  • A paid tester found 120 A continuous printed on the battery's label against 150 A on Renogy's site

RedditBrand-level5.0 out of 10

Reddit owners split on Renogy's LiFePO4 batteries. An r/vandwellers full-timer reports three 100 Ah smart lithium batteries at 96 percent capacity after 5 years, and an r/overlanding owner is in year four with a 100 Ah running a fridge. Against that, an r/SolarDIY installer had two batteries' BMSs fail and the warranty claim denied despite capacity-test videos (2023), another r/SolarDIY owner's battery would not hold charge past 4 hours (2026), and an r/vandwellers owner says theirs had not held up after 3 years.

GoogleBrand-level5.0 out of 10

DIY Solar Forum owners report Renogy batteries failing early and Renogy replacing most of them. In a 2022 teardown thread a 50 Ah pack stopped accepting charge after about 20 cycles, and a 2025 reply describes two 50 Ah packs falling to about 30 Ah before Renogy replaced both with a 100 Ah Mini. One of four 200 Ah Bluetooth batteries arrived with a 0.4 V cell deviation and was replaced (2023), and a 48 V 50 Ah owner had one of eight packs fail on a bad cell at two years, replaced under warranty after what he called a painful service process (2025).

Every channel found carries a Renogy tie. Mike Builds, in a video marked as paid promotion, measured 123.5 Ah against the 120 Ah rating and found the battery's label printing 120 A maximum continuous discharge against the 150 A on Renogy's site (January 2026). Adventure Tech 2.0, whose episode is brought to you by Renogy and which carries the discount code ADVENTURETECH, installed and tested the 120 Ah unit (January 2026).

Renogy is the brand of RNG International, Inc., of Ontario, California, which Dr. Yi Li founded in 2010.

It sells direct from renogy.com and its Amazon and eBay brand stores, and through Home Depot, Lowe's, Best Buy, Camping World and Walmart's marketplace.

The Renogy Pro S1 12V 120Ah (RBT12120LFP-SBH) is a 12.8 V, 120 Ah lithium iron phosphate battery rated 1,536 Wh, in a 12.8 x 7.44 x 7.4 in IP67 case that weighs 29.5 lb. Renogy describes its cells as semi-solid-state, with about 70 percent less liquid electrolyte than conventional lithium-ion cells, and states that no fully solid-state battery is on the market. Its BMS is rated 120 A continuous charge, 150 A continuous discharge and 350 A for 30 seconds, and Renogy rates it for 6,000 cycles at 80 percent depth of discharge, retaining 80 percent of capacity. An 85 W heater runs below 41 °F (5 °C) while charge current stays above 10 A and, by the manual, takes about 2 hours to warm the pack from -4 °F to 32 °F. Bluetooth is built in, and two RJ45 CAN ports link batteries to each other and to Renogy chargers and monitors; the cables and termination resistors are sold separately. Renogy rates it 4S4P, 16 batteries at most, for 48 V (51.2 V) and 24.576 kWh. The box includes four fix brackets with 16 combined bolts and 8 self-tapping screws, and two lengths of M8 terminal bolt. Renogy sells a 2-pack for $899.00.
