After your 4 12v batteries are all topped off take them out of parallel and wire them in series. A parallel configuration is not meant to.
Serial And Parallel Battery Configurations And Information
Charging batteries in series vs parallel. Use google fu not an endorsement and the search term battery charger ic then find one that fits your needs. Two 12 volt batteries wired in series produce 24 volts but the capacity remains the same as one for a 12 volt battery. Connecting batteries in series adds the voltage of the two batteries but it keeps the same amperage rating also known as amp hours. Two 12 volt batteries wired in parallel continue to produce 12 volts but the capacity doubles. Laptop batteries commonly have four 36v li ion cells in series to achieve a nominal voltage 144v and two in parallel to boost the capacity from 2400mah to 4800mah. Charging 12 volt batteries wired in parallel requires a 12 volt battery charger.
Hence when charging these batteries it is important to utilize a charger that satisfies the 12 volt capacity that is necessary for both the 6 volt batteries connected in series. For example two 6 volt batteries connected in series will deliver 12 volts of output but will carry the same amp hour capacity. Such a configuration is called 4s2p meaning four cells in series and two in parallel. Iota power products technical library. Custom charging configurations can consist of multiple chargers arranged in either series or parallel configurations or a combination of both to increase output voltage or capacity. This means you have a fully charged 48v battery pack with each battery at the same state of charge.
Endgroup sparky256 may 7 16 at 2002. Insight batteries can only be connected in parallel and allows for up to 10 batteries in parallel. Lets start with the series method as we compare series vs parallel. Its important to understand the difference between parallel and series configurations and the effects they have on your battery banks performance. Hp series batteries can be connected in parallel only. Maintenance over time it is good to check your individual batteries with a voltmeter.
Begingroup there are special charging ics on the market that select one battery at a time to monitor and charge even if in series with many batteries. In contrast batteries connected in a parallel configuration are able to increase the amp hour capacity of your batteries at the same voltage. Although theoretically it should be equal the truth is that due to manufacturing differences or low quality connections the charging and discharging current that will flow throughout. How to wire batteries in series. However a parallel connection also means that the charging current that is used to charge all the bank will be divided between every string of batteries. For example these two 6 volt batteries joined in series now produce 12 volts but they still have a total capacity of 10 amps.
Series configurations may be used to increase output voltage of the chargers to match the voltage of the battery and when space constraints require a custom charging design.
