Description
The main advantage of the FTS-X series is the increased specific capacity. The FTS-X series’ specific capacity is 15% higher than the average one, which allows to install more batteries in a fixed area. FTS-X batteries are optimal for use in both short and long discharge modes. This series demonstrates a high uniformity of quality indicators, which contributes to the extended duration of operation.
