Charging 12 volt batteries wired in parallel requires a 12 volt battery charger. For example if charging one battery normally takes three hours and you have five batteries linked in parallel the charging time will be five times three hours or 15 hours.

Charging multiple batteries in parallel. Is parallel charging risky. Parallel charging is also very convenient as it saves you from having to constantly unplug one battery to connect another one to the charger. Two 12 volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12 volt battery. When you connect multiple batteries in parallel connect the of the first battery to the of the second battery. For secondary rechargeable batteries the stronger battery would charge the weaker one draining itself and wasting energy. You can charge multiple batteries in parallel with just one single charger.
Following this example where there are two 12v 200ah batteries connected in parallel we will therefore have a voltage of 12v volts and a total capacity of 400ah ampere hour. The parallel connection of two identical batteries allows to get twice the capacity of the individual batteries keeping the same rated voltage. Multiply the time anticipated to charge one battery by the total number of batteries. What does this mean to you. When you connect the batteries in parallel you are keeping the total voltage the same. In a nutshell parallel charging allows for multiple same cell count batteries to be connected in parallel to create a single larger logical battery that can then be charged.
If you connect rechargeable batteries in parallel and one is discharged while the others are charged the charged batteries will attempt to charge the discharged battery. Parallel charging is a fast and cost effective way to charge a lot of lipo batteries at the same time. Connect the positive output of the charger to the positive terminal of the first battery and connect that positive terminal to the positive terminal of the second battery. An example method of charging batteries in parallel is to use one branch of the parallel circuit to charge each battery with a single charger. Parallel charging lets you charge multiple lipo batteries at the same time on the same charger. Batteries may be wired in parallel or in series.
Say you have 3 3s 2200 packs that you run in your 450 sized heli. Parallel charging is hugely useful if you have a high wattage charger and lots of small batteries. Two 12 volt batteries wired in parallel continue to produce 12 volts but the capacity doubles. For example if you connect two 12 volt batteries in parallel the voltage of the combination is 12 volts.
