If I take one battery away from each set then I still have 24vdc at the output cables of the second battery. 5) As Bruce indicated, be very careful about using two separate to charge a 24 volt series setup. Keep in mind that the POS and NEG on charger #1 will be connected to POS and NEG on BAT #1.

You can wire 3 of these batteries in series to obtain 12 volts. Two 6 volt batteries in series will work to power the light. The length of time you can run the light depends entirely on the capacity rating of the 6v batteries. Yes, what you suggested can also work to accomplish the same output. If you have two batteries in series, then technically there is only one ‘open’ positive and negative post in each bank.
The leads to inverter are attached to opposite corners of the bank. Wire the series first, then wire the series sets in parallel. I have used this battery charger for about two years so far and it is the best one I have ever bought. I am able to use it in any weather condition outside, and then take it back inside and it still works great. Charging capability is unbeatable, going from a small lawn mower to a monster truck battery. Simply remove your existing lead-acid batteries, insert Allied commercial battery, attach cables, secure holding brackets and the install is complete.
Replacing one battery will technically work, but like you said it will cause the rest of the batteries to forsake whatever natural lifespan they would have had. Someday you should replace all the batteries at the same time. Please use our load/battery capacity calculator in the tools section of our Knowledge Base to find the answer you are looking for. What capacity batteries required for longest life, and how should I arrange them. Two 12v 40 AH in parallel bank and one 12v 75AH battery in series with it.

I recommend you measure the voltage from each battery, and see where the difference is. If one battery is heavily sulfated and discharges quickly, it will also bring down the other batteries in an attempt to equalize charge across the entire bank. Yes, if the different banks are connected to a common bus bar, and they are discharged more than other banks, there will be back flow. Can you suggest me how to isolate the two battery banks during charging. We recommend having an even and balanced battery bank. Therefore, you should only use 4 of the batteries, or buy 2 more for 8 in total.
I would would recommend contacting our Tech Department for suggestions. The smaller capacity battery can become overcharged, and could fail bringing down the whole pack. It is never recommend to mix and match different battery chemistry, types, and size. Parallel but not a difference in output after achieving 12v,400amp. I thought I’ll get more back up hours what could be the problem. I removed the leads to charge each batt separately with my 12V charger.
What is a 24V Battery?
Avoid mixing and matching battery sizes wherever possible. When wiring batteries in series, try to use identical batteries which are the same age and condition. Buying a ‘spare’ battery to replace one that might die is probably not worthwhile.
If not, then I would suggest tracking down the parasite draw. It really wouldn’t be recommend, as you would start to unbalance the battery pack, which could later result in a battery getting overcharged. If this happens too often the battery could fail and bring down the whole pack. Realistically, the voltage you select is dependent on your application. As far as hooking them up I would suggest reading the article on how to configure them. If you need more assistance I would suggest contacting your local battery dealer for a more in-depth explanation.
Charging 12V batteries in series-parallel using a 24V charger
Also my solar panel is capable of charging both and has 1 Anderson plug. Will it evenly charge if plugged into one box or like the outward power do I need to put positive to one battery and negative to the other. Different wiring configurations give us different voltages or amp hour capacities.This article deals with issues surrounding wiring in parallel (i.e. increasing amp hour capacity). For more information on wiring in series see Connecting batteries in series, or our article on building battery banks.
Hi There, I have bought a 30 year old boat that has two banks of three 12v 75Ah batteries, two are connected in series and one in parallel. However I seem to have an extra problem, when left with the main breaker switch off the two connected in series slowly loose their charge. Is this due to the bad setup or is it likely to be a drain somewhere? I would have thought that if any of them were to drain it would be the one in parallel.
As David alludes to above, too few, or too many amps is problematic. Here are general rules of thumb for different battery chemistries, where «C» is capacity in Amphours , measured over a 20 hour period. That means the TOTAL number of Amphours you get draining the battery slowly over a 20 hour time period. Attach the wire from the positive terminal of your power system to one of the positive terminals in the first set of batteries.
The voltage of batteries drops as they are discharged. Most battery operated devices are designed to recognize this drop in voltage and stop operating. So, a 6 volt device may stop working when the battery supply drops to 5 volts. This fail safe is designed to stop excessive discharge of the battery which would shorten its life.
After wiring the Minn Kota 24v trolling motor , remember to keep the positive terminals covered with protective shields or proper electrical tape to avoid shorts and possible fire danger. This could be done in Series, but the MyHornySingles support AH amperage ratings for each battery would need to be the same to prevent irregularities. 18 volts should increase speed without putting too much strain on the motor or gears, but can’t guarantee it wearing out quicker.
