As in the diagram above two 6 volt 45 ah batteries wired in series are capable of providing. By charging 6 volt batteries in series with a 12 volt charger you allow your off grid electrical the true capacity it needs.

Charging 4 12v batteries in series. Then connect the negative end of the battery to the positive end of the next one and continue to do so for the rest of your batteries. You need to overcome the total voltage of the series batteries 12 v 12 v 24 v to drive. To charge two 12 volt batteries in series youd need a 24 volt charger. Some chargers have a light that illuminates once charged. Plug in your charger to the electricity supply. Assuming you have la batteries that means you probably have 4 12v batteries that are connected in series which 48v 4 batts 12v.
After your 4 12v batteries are all topped off take them out of parallel and wire them in series. One basic configuration for charging batteries in series is to connect the positive charger output in red to the positive end of one of the batteries. Use another set of cables to connect the open positive and negative terminals to your application. Others have a meter that shows the charge rate and once its near zero your batteries are charged. Thats the pat answer. In theory a 6 volt 5 ah battery and a 12 volt 5 ah battery connected in series will give a.
If they are some other chemistry eg. Li ion batteries do not follow the advice below. Note that a 12v battery will charge to approx. For the final battery connect the negative end of the battery to the negative output in black of the charger. Two 6 volt batteries in series vs one 12 volt life cycles. Using like sealed vs.
Of the smaller battery through the over discharging and over recharging described and shorten the life of the larger battery through under charging. 147v total and then float around 135v. To connect batteries in a series use jumper wire to connect the negative terminal of the first battery to the positive terminal of the second battery. Let your batteries charge until the charger indicates they are fully charged. Charging only some of the batteries will result in batteries attempting to equal out the power and charging each other. Discharging down do 80 depth of discharge 600 700 on average.
Before doing anything that i suggest below make sure your batteries are 12v lead acid batteries. You could also use four separate 12 volt chargers each one charging one of the four 12 volt batteries making up the 48 volt bank as long as the outputs of the chargers are not connected to each other except at the batteries. Charge more than five batteries by connecting one 12 volt battery charger across each battery in the series as if each battery were the only one being charged. 6 volt agm battery has more life cycles. This means you have a fully charged 48v battery pack with each battery at the same state of charge. A 12v agm battery on average has only 150.
Turn on your charger ensuring it is set to charge at 12 volts. Charge all the batteries at the same time. Maintenance over time it is good to check your individual batteries with a voltmeter.
