Here were some lipos that were getting a good work out, four 5amp 5s batteries, two wired in series to run two motors on 10s. Runs for about three min and pulls 400+ amps total. Both 10s batteries got completely soaked and the fe rx battery too. Silicone gel and baggies for a few days and still in use from two years ago. Yes they are quality batteries and well taken care of. Well they get worked hard, and on the way out as of lately but served a very good span.
