How to choose the best lithium battery for RV Group 24
Fit and the Group 24 box
The Litime self-heating battery is stated as a universal Group 24 fit, the SUPER EMPOWER measures 6.49 by 10.24 by 8.98 inches with M8 terminals as a drop-in replacement, and the HumsiENK meets BCI Group 24 to 31 at 8.4 by 6.6 by 10.2 inches. Measure your box before ordering; Group 24 is a size, not a brand. For the category, see our LiFePO4 battery guides.
Cold weather features
The Litime self-heating battery heats below 41 degrees F and stops at 50 degrees F to start charging, with regular and energy-efficient modes. The other three rely on low-temperature cutoffs: charging pauses at 32 degrees F on the SUPER EMPOWER and the Litime 2-pack, while the HumsiENK operates from -4 to 158 degrees F and shuts down below -4.
Certifications and cycle life
The HumsiENK states UN38.3, FCC, CE and ROHS with an IP67 rating; the Litime pair states IP65 with AIG product liability insurance. On cycles, the self-heating Litime states 4000+ at 100% DOD, the HumsiENK 5000 at 100% DOD, and the Litime 2-pack 4000+ in the bullets against a max-15000 title, so trust the bullets.
| Battery | Certifications | Cycle life | Cold weather |
|---|---|---|---|
| HumsiENK 100Ah 2-Pack | UN38.3, FCC, CE, ROHS | 5000 at 100% DOD | -4 to 158 F |
| Litime Self-Heating 100Ah | IP65 | 4000+ at 100% DOD | Self-heating |
| Litime 100Ah 2-Pack | IP65 | 4000+ per bullets | Low-temp cutoff |
| SUPER EMPOWER 100Ah 2-Pack | Not stated | Not stated | Low-temp cutoff |
Bluetooth and expansion
Bluetooth monitoring is stated on the Litime self-heating battery and the Litime 2-pack, not on the HumsiENK or SUPER EMPOWER. Expansion: 4P4S to 20.48kWh on the Litime pair and the SUPER EMPOWER, and 4S/4P to 48V 20kWh on the HumsiENK. For staying powered off-grid, see our best lithium battery for off grid solar guide.
Sizing Notes
- Match the box first: Group 24 dimensions run about 10.24 by 6.61 by 8.89 inches here.
- Check cycle life against its DOD: 4000+ and 5000 figures are at 100% DOD where stated.
- Line up cold-weather behavior: self-heating (Litime) against charge cutoffs at 32 degrees F.
- Count batteries in the pack: 2-packs on three listings, a single on the self-heating Litime.
