Hi Im new to this but I just got this boat for christmas the Atlantio 059 with two motors, and a 7.2 v 1800 MAH, and I want to upgrade the battery so it last longer than 15 to 20 min, Now I went and got same volt battery pack but 3800 MAH will this setup work or would it burn my motors, also Im installing a twin engine water cooling system before I try this new battery. Any idea what should i upgrade with the battery to make this little boat last longer and run a little faster. Thank you all.
