Like many other electro-mechanical devices, RC boats require a battery to operate. However, the boats can only go as far as the battery charge allows.\n\n\n\nHow long should an RC boat battery last? RC boat batteries can last for one to three hours, depending on the type and amount of juice in the cells. Each battery type will last a different period of time and the way you use the boat will also cause the time to vary. If you use the boat at full throttle constantly the battery won't last as long as it would if you were going a slower speed. \n\n\n\nAn RC boat battery powers everything in the boat. Even nitro-powered RC boats require a battery to operate. There are different types of RC boat batteries, each with specific charging requirements.\n\n\n\nTypes of RC Boat Batteries and How Long They Last\n\n\n\nKnow the types of batteries used in RC boats and how long they last. This can facilitate an informed decision when purchasing an RC boat.\n\n\n\nNiMH and LiPo Batteries\n\n\n\nTwo main types of batteries are used to power electric RC boats:\n\n\n\nNickel metal hydride \tLithium polymer\n\n\n\nNiMH and LiPo are the essential elements that react to store electricity inside the cells. The chemicals contained in the two types of batteries have distinct pros and cons.\n\n\n\nMany ready to run RC boat models come with NiMH batteries. This type of battery is:\n\n\n\nAffordable \tDoes not require special care \t\n\n\n\nOn the downside, NiMH batteries are heavier than LiPo batteries of similar voltage and capacity. In addition, NiMH battery voltage decreases as the pack discharges.\n\n\n\nOnce you start operating the RC boat, its voltage decreases with the discharge of the pack. This means the boat will begin to go slower with each minute of use.\n\n\n\nLiPo batteries are often sold as accessories in many cases. However, some ready to run RC boats feature LiPo batteries.\n\n\n\nUnlike NiMH batteries, LiPo batteries are lighter, which makes RC boats with such cells feel more powerful. The feeling of power or punch is also heightened by the fact that LiPo batteries can maintain voltage for longer than NiMH batteries.\n\n\n\nLiPo batteries can hold a steady voltage for a prolonged period and then lose power quickly at the end of the charge. On the downside, LiPo batteries are more expensive than NiMH batteries.\n\n\n\nLiPo batteries also require special care to make them last for longer and enhance user safety. This type of battery often comes in two or three cell configuration.\n\n\n\nCapacity and Voltage\n\n\n\nThe main factors to consider when comparing batteries:\n\n\n\nCapacity \tVoltage\n\n\n\nCapacity\n\n\n\nCapacity determines the length of time your battery will run with each charge. On the other hand, voltage determines the speed and power the battery will deliver.\n\n\n\nBatteries usually feature a number on their labels. The big numbers on the label, 1000, 2000, 3000, indicate the capacity in milliamp hours or mAh. Batteries with higher numbers take longer to recharge, and the longer the RC boat will run per charge.\n\n\n\nIt is essential to understand what mAh means. A 5000 mAh battery can hold the 5-amp load for an hour.\n\n\n\nOne milliamp is a thousandth of an amp (1\/1000 of an amp). Therefore, the number of amps in a battery can be obtained by dividing the mAh rating of a cell by 1000.\n\n\n\nVoltage\n\n\n\nBattery voltage is only suitable up to a certain extent. The power system of your RC boat is designed to handle a certain amount of voltage.\n\n\n\nExceeding the voltage may lead to:\n\n\n\nThe shutdown of the entire system \tFrying of your RC boat electronics\n\n\n\nThe voltage of a pack of batteries is determined by the number of cells it has. One NiMH cell can deliver up to 1.2 volts.\n\n\n\nNiMH batteries are usually packed in six or seven cells. LiPo batteries have fewer cells in each pack because of their higher voltage.\n\n\n\nThe \u201cS\u201d Designation\n\n\n\nBoth NiMH and LiPo batteries are referred to by the number of cells in their packs. In addition, LiPo packs may have the \u201cS\u201d designation including 2S, 3S or 4S.\n\n\n\nThe \u201cS\u201d stands for series, which means the cells in the pack are connected parallel to each other or in a series. However, some LiPo batteries are connected in both parallel and series.\n\n\n\nA "P designates the parallel cell connection." Therefore, cells with both parallel and series connections are designated by both "S" and "P."\n\n\n\nA \u201c2S2P\u201d LiPo has two pairs of cells, one pair wired parallel, and the other wired in a series. However, many LiPo batteries are wired in a series.\n\n\n\nRC Battery Charging Tips\n\n\n\nBe sure to use a NiMH charger if you have NiMH batteries and a LiPo charger if you have LiPo batteries. If your RC boat has both types of cells, make sure you use the appropriate charger.\n\n\n\nConsider the amperage of the charger. The higher the amperage of the charger, the faster it will charge.\n\n\n\nAlthough higher amperage chargers provide faster charging, that may not be the best thing for your RC boat battery. Giving your cells more juice than they can handle could fry them up. \n\n\n\nIt is essential to charge your batteries at lower amperage to extend your batteries' life. Charge LiPo packs at the same rate as their capacity.\n\n\n\nAlways charge your batteries at a rate of 1C, which means capacity multiplied by one. LiPo batteries can handle charging at higher rates, but doing so will reduce their life expectancy.\n\n\n\nNiMH batteries can tolerate charging at a higher amperage, but its always good practice to charge the batteries at a rate of 1C to maximize battery life. However, an occasional charge at a higher amperage to save time will not hurt the cells so much.\n\n\n\nBattery Charging Safety\n\n\n\nRC batteries require safe and careful handling. Otherwise, they can be quite dangerous to your health, especially when they explode or start to leak.\n\n\n\nRule #1\n\n\n\nAvoid leaving your RC boat batteries unattended while charging. Although most batteries would charge without experiencing any problems, they may overheat during charging or develop other issues on rare occasions.\n\n\n\nRule #2\n\n\n\nBe sure to use the right type of charger for your RC boat batteries. LiPo batteries are not designed for charging with NiMH chargers.\n\n\n\nUsing a NiMH charger on your LiPo battery could cause it to catch fire. Use a LiPo charger to charge LiPo batteries or put the multi-mode charger on LiPo charge mode.\n\n\n\nRule #3\n\n\n\nUse the right connectors or appropriate adapter. Avoid rigging connections with exposed wires and clips to prevent a short circuit, which may damage the battery and cause it to catch fire.\n\n\n\nTo enhance safety when charging your RC boat battery, consider using a flame-retardant charging bag.\n\n\n\nLipo Balancing\n\n\n\nWhen shopping for a LiPo charger, choose one that can balance the cells in the pack as it charges. A balanced pack means that cells have a similar voltage.\n\n\n\nLiPo balancing helps to prevent drifting of the voltage of cells in a pack, which usually happens during charging and discharging. LiPo cells can become damaged when over-discharged.\n\n\n\nTo ensure the cells have equal voltage during charging and discharging, be sure to use a LiPo charger that balances the cells in a pack. Make sure the balance plug of the cells is plugged into the charger.\n\n\n\nSome chargers have built-in balance plugs, while others have external balance boards. The balance plug is usually a small white connector on the LiPo pack.\n\n\n\n A LiPo plug is usually wired so that it can provide accurate readings for each cell\u2019s voltage.\n\n\n\nLiPo Battery Maintenance\n\n\n\nProper maintenance maximizes the service life of your LiPo batteries. To get the most out of your LiPo batteries:\n\n\n\nUse chargers with low voltage detection Keep the battery pack clean Make sure you store your batteries when they are at least 50 percent charged\n\n\n\nAvoid Fires\n\n\n\nIf you aren't careful when charging your battery it can become damaged or even explode!

Some people would prefer to run their boat as fast as possible while other people prefer to do maneuvers instead of running at higher speeds. How you use your boat has a huge impact on how long the battery will last. \n\n\n\nIf your battery isn\u2019t lasting as long as you would like you can upgrade to a better battery in most boats. If you choose to go this route, make sure to get a battery that is compatible with your boat\u2019s model so you don\u2019t damage any of the boat\u2019s electronics.
