The short answer on litime 100ah vs renogy 100ah: both listings describe a lithium iron phosphate battery for RV, marine and off-grid use, and the choice comes down to cold weather and stated protections, since both state the same capacity. We compared the two listings on weight, size, cycle claims, self-heating, BMS protection and warranty terms. The Renogy states self-heating and a wide temperature range, while the LiTime states expansion to a larger bank and a Group 24 fit.

Litime 100ah vs Renogy 100ah: side by side
| Battery | Solar Score | Capacity | Weight | Cycle claim | Cold features | Warranty |
|---|---|---|---|---|---|---|
| Renogy 12V 100Ah Self-Heating | 9.7/10 | 12V, 100Ah, 1280Wh | 21.38 lb | 5000+ at 80% DOD | Self-heating, -22°F to 131°F | 5 years |
| LiTime 12V 100Ah Group 24 | 9.7/10 | 12.8V, 100Ah, 1280Wh | 21.0 lb | 4000+ at 100% DOD | Not stated | 5 years |
These specs are rated by the maker and quoted from each listing on 5 November 2026.
Weight and size
The two batteries sit close on weight and size. The LiTime is listed at 21.0 pounds in a Group 24 case of 6.61 by 10.24 by 8.27 inches, and the Renogy at 21.38 pounds in a Group 22NF case of 5.43 by 9.02 by 8.0 inches. The Renogy listing calls its case 45% smaller than similar batteries, while the LiTime listing calls its Group 24 size a drop-in fit for RVs replacing AGM. Both state 1280Wh, so the tray fit matters more than the weight gap.
Protection and cold weather
Protection is where the listings part ways. The Renogy states a 100A BMS with 25+ safety features and IP65 casing, plus dual heating pads at 110W that warm the battery 40% faster and a stated range of -22°F to 131°F. The LiTime states a BMS that guards against overcharge, over-discharge and overcurrent, with Grade-A LiFePO4 cells, and states no IP code and no temperature range. If your battery sits outside heated space in winter, the Renogy states the cold-weather features; the LiTime leaves that part unclear.
What the listings leave unclear
LiTime’s title claims up to 15000 cycles while its bullets state 4000+ cycles at 100% DOD with a 10-year life, so compare on the lower figure. The Renogy title claims 5000+ deep cycles and its bullets state over 5000 cycles at 80% DOD, which lines up. The LiTime states no temperature range and no IP code, and the Renogy states no expansion figure. Neither listing states UL certification.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For RV house batteries, safety means a battery management system, cold protection or another protection the listing names; both batteries here state a BMS, and only the Renogy states an IP code. Both state a 5-year warranty. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Renogy 12V 100Ah Self-Heating | 9.7 | 32 | 22 | 21 | 9 | 3 |
| LiTime 12V 100Ah Group 24 | 9.7 | 30 | 21 | 21 | 8 | 3 |
Every total is translated into a figure between 9.2 and 9.8 with a linear formula; ranking by points and ranking by score always agree.
Litime 100ah vs Renogy 100ah: which should you choose?
Choose the Renogy if you camp in cold weather and want stated self-heating, a 100A BMS and IP65 casing in a compact Group 22NF case. Choose the LiTime if you have a Group 24 tray and want a drop-in AGM replacement with room to grow the bank to 20.48kWh later. Both state 1280Wh and a 5-year warranty, so the choice is about fit and cold weather, not capacity.
