For something as large and heavy as a LST (high current) you are going to want very good cells (Nue or FlightPower) or another brand battery of similar spec. Anything else will struggle to dish out enough power and will suffer doing it. Better have too good of a battery sleep while you run your truck than a battery thats not good enough die trying (and take half your truck with it).
