I have been buying RC cars, trucks, planes, helicopters, and boats for about 20 years. For a charger that measures the pack as a whole, all you would see is the 12 mΩ - the rest would be done for you - behind the scenes, as it were. As LiPo battery is used, a build of up Li2O forms on the inside terminals of the battery (we'll go more in depth on this later in the Discharging section). After many, many uses, the battery will simply wear out and be unable to hold on to any energy you put in during charging - most of it will be lost as heat.
So our battery would experience a tiny drop in voltage when a 1A load is applied. And if your charger doesn't give you the per cell measurements, you'll have to divide your total count by the number of cells in your battery to get an approximate per cell rating. However, there is a correlation between the C-Rating of a battery and the internal resistance of that battery. Basically, the charger will keep the current, or charge rate, constant until the battery reaches its peak voltage (4.2v per cell in a battery pack).
On the other hand, NiMH and NiCd batteries charge best using a pulse charging method. Charging a LiPo battery in this way can have damaging effects, so it's important to have a LiPo-compatible charger. Balancing is a term we use to describe the act of equalizing the voltage of each cell in a battery pack. Just as the C Rating of a battery determines what the safe continuous discharge of the battery is, there is a C Rating for charging as well.
While there are stand-alone balancers on the market, I recommend purchasing a charger with built-in balancing capabilities, using a balance board like the one pictured to the right. And with the price of chargers with built-in balancers coming down to very reasonable levels, I can't think of a reason you would not want to simplify your charging set up. We'll talk more about chargers in the next section. While we would routinely charge a 3000mAh NiMH battery at four or five amps, a LiPo battery of the same capacity should be charged at no more than three amps. It can even charge the newest LiFe batteries that some use for receiver packs in airplanes and cars.
I prefer a CO2 (Carbon Dioxide) extinguisher - it helps to remove oxygen from the burn site, and will also cool down the battery and surrounding items. While you don't have to always be in the same room, you shouldn't leave the house, or go mow the lawn, or anything else that will prevent you from taking action should the battery catch fire. If you need to charge multiple batteries at the same time, the Dynamite Prophet Sport Quad 50W charger is probably the best bet. Each port on the Dynamite quad charger is 50W, and they also have that 100W version.
