It is a 4s lifepo actually smaller one ( there is only 2 version at HK) . The most important benefit of this batery is 13.2 volt and all 12 volt stuff support it. I can drive loader non stop 3*4 hours. (after that much work naturally hydrolic pump burning) .
With the same battery I can drive my truck 5*6 hour nonstop or 3-4 hour wedico cat 345 D . As short I have 4 from this batery and I can drive all my machines nonstop from noon to evening
