Need more battery capacity without losing valuable storage space?
A standard lithium battery can take up a lot of valuable room, especially in a 4WD, ute canopy or caravan. This is where a slimline battery makes a real difference.
The TPower 12V 135Ah Slimline LiFePO4 Battery gives you serious capacity in a narrow 110mm design, making it much easier to work into tight installations without sacrificing as much storage space.
12.8V 135Ah LiFePO4
1728Wh rated energy
100A continuous discharge
300A peak discharge for up to 5 seconds
395 × 110 × 293mm
13.8kg
For inverter setups, a 1000W inverter is a sensible match for this battery. The 100A continuous discharge rating gives approximately 1280W DC output at nominal voltage, leaving some allowance for inverter losses and operating margin.
The 300A peak output is for short startup surges only and is not a continuous output rating.
