Beyond the balancing connector, most batteries have a primary connection used to connect the battery to your aircraft and to the charger.
Astro Blinky Balancer Full Article InRead the full article in the September 2015 issue of Model Aviation.LiPo batteries rose to popularity with their ability to provide longer flight times with less weight as compared to the NiMh and Ni-Cd batteries they have largely replaced.The saying with great power comes great responsibility would be a fitting description when describing LiPo batteries, but understanding the basics of this battery technology and having a working understanding of your charger will go a long way. Although some RTF aircraft come with basic chargers, we are going to focus on stand-alone chargers that offer more flexibility, and functionality. When it comes time to purchase your first charger, or possibly a replacement charger, there are many things to consider such as input power, output power (in watts), capability to charge single or multiple battery packs at the same time, number of cells supported, balancing, and computer connectivity (for tracking and updates). Selecting a charger with an LCD screen is also a good idea so that you can easy and accurately change charging parameters and monitor the charge cycle and the voltage of individual cells. Chargers receive power from alternating current (AC), direct current (DC), or have the option to use either one. An AC charger has a built-in power supply allowing it to be plugged into a wall socket, making it handy to charge batteries anywhere there is an available outlet. DC power comes by either plugging the charger into a power supply or by connecting it to a battery. This is convenient for charging at the field or at events when electrical outlets are unavailable. Watts are calculated by multiplying the voltage and the amps. A fully charged 2,200 mAh 3S LiPo battery would have a voltage of 12.6. Charging at 1C, it would draw roughly 28 watts of power (12.6 volts x 2.2 amps 27.72 watts). As you might expect, charging at a higher C rating will increase the required wattage needed from the charger. Multiport chargers allow two or more batteries to be connected to the charger and simultaneously charged. The only drawback is that the separate ports on the charger split the available wattage, so a four-port charger might only support 50 watts per channel versus 200 watts that might be supported on a single charger. This DC charger can be purchased with a matching power supply. Balance charging LiPo batteries is essential to getting the most from your batteries by ensuring that the voltage of each individual cell in a pack is equal. Balancing helps prevent single cells from being overcharged or discharged, which can damage the cell and has the potential to cause a fire. The balancing process will typically discharge the higher-voltage cells to match the lower-voltage cells during the charging process. Balancing can also be done with stand-alone products such as the Astro Flight Blinky LiPo Battery Balancer. LiPo batteries composed of two cells or more could utilize one of four balancing connectors: XH, EH, HPPQ, and TP. Some chargers include one or more balancing boards and some have all four on one board. If your charger doesnt have the balancing connector to match your batteries, you can probably purchase one. E-flite and ElectriFly are examples of brands that use this plug.
