TN84 Lithium Leisure Battery LiFePO4 

LiFePO4 (lithium-iron-phosphate) batteries exhibit remarkable power density and longevity, positioning them as an excellent choice for weight and lifespan-conscious off-grid applications. Our thorough research and testing confirm that TN Power batteries offer unparalleled value in terms of performance, solidifying their status as our preferred battery option for a wide range of uses. The TN Power lithium leisure batteries boast an impressive cycle life of 3500 cycles at 80% Depth of Discharge (DOD).

TN Power lithium leisure batteries excel in off-grid scenarios where deep discharging is essential, and the considerations of weight and size hold utmost importance.

Weighing 10.2kg, the TN Power 84Ah lithium battery features M8 threaded connection posts for convenient setup.

The 12.8V TN Power lithium batteries are constructed from four cells interconnected in series.

Please take note: You can parallelly connect up to 2 TN Power batteries, resulting in a combined battery bank capacity of 168Ah.

Lifespan of TN Power lithium leisure batteries:

  • 80% DOD – 3500 cycles
  • 70% DOD – 4000 cycles
  • 50% DOD – 5500 cycles

This signifies that a lithium leisure battery configured to provide 3 full days of power based on your daily consumption, when used daily (i.e., in full-time applications), will endure for approximately 15-20 years. In comparison, an AGM leisure battery with similar specifications and usage will last around 3-4 years.

Lithium leisure batteries cater to a variety of use cases, excelling in situations where deep discharge of over 90% capacity is necessary. This attribute ensures the vast majority of the battery's capacity is accessible. With over 50% lighter weight and smaller dimensions compared to lead-acid counterparts, lithium batteries are perfectly suited for weight and space-conscious off-grid applications like campervans and boats.

Lithium leisure batteries are particularly suitable for those with consistent full-time usage, such as living on a narrowboat or being full-time van lifers, benefiting from their prolonged lifespan that eliminates the need for frequent replacement, a common concern with lead-acid batteries.
