Not sure if I cycled the batteerys exactly right, did a slow charge twice, discharged twice THEN.....hehehehe put the new Tenergy 7 cell 4500"s onto there smart chargers (got 2) on 1.8 amps. It took 1 hour 55 min. Now the important stuff... The boat is a totally sick rocket... How can I decribe it.. sick, totally insain, animal, unbelievable, I am absolutly SHOCKED. These batterys a seriously very good, excellnt. I ran that boat for at least 6 miniutes, brought it in to check everything. The batterys were luke warm, the speed control not even warm, the motor was more then warm but not hot. Same packs back in... at least 6 or 7 more miniutes of the exact punch I had when the run first started. The boat slowed all at once, the cells are definatly matched pretty good. The pack were warm, not in the least bit hot. The motor was to hot for me, I need to upgrade the cooling. I will say I like the stock prop. Almost wish I didnt order any others. I need adjustable trim tabs. Here is the deal I got....... they deserve the mention.
