Strengths and limitations
Strengths
- 100 A continuous, 200 A surge for 30 seconds (Battle Born).
- 3,000 to 5,000 deep discharge cycles (Battle Born).
- Fits Group 27 and Group 31 battery spaces; 12.76 x 6.86 x 8.95 in (Battle Born).
- IP65; cells UL Recognized to UL 1642, pack ETL listed to UL 62133-2 and UL 2054, UN38.3 (Battle Born).
Limitations
- Neither the product page nor the data sheet states the warranty or the capacity in watt-hours.
- Set your charger and controller to Battle Born's lithium voltages: 14.2 to 14.6 V absorption, 13.4 to 13.8 V float.
What it does not do
- Feed a big inverter alone: it is limited to 100 A continuous (200 A for 30 seconds), and a 3,000 VA inverter at 12 V needs far more. Plan batteries in parallel.
- Charge faster than 50 A (Battle Born data sheet).
- Settle cold charging clearly: the install guide gives a 25 F charge floor with a low-temperature cutoff, while the data sheet lists 25 F under "heated model only". Until Battle Born clarifies, treat freezing (32 F) as the floor for the standard model. That is our caution, not a maker figure.

Before you buy
- Fuse every battery cable close to the battery; large 12 V inverters pull very high current.
