#Battery status in parallel connection how to

You can make small to large battery banks with the help of those connections even I have built a 48V and 550Ah for my heavy-duty golf cart with the help of series-parallel connections.īelow is the step by step guides to making long-lasting battery connections How To Connect Batteries In Seriesīefore starting the step-by-step guide we are going to confirm a few things, the series connection will only increase the voltages, not capacity (amp. Make sure to wear old cloths to avoid any damage, otherwise acid will destroy your new cloths.īatteries can be connected in series, parallel, or series-parallel depending on your demands.Take off metallic chains or rings, metal can be easily attacked by electricity make sure to remove your bracelet, rings or even chains.Safety Measures Should Be Taken Before Connecting The Batteries Best Practices To Connect The Batteries In Series, Parallel Or Series – Parallel.How To Connect Batteries In Series-Parallel.Safety Measures Should Be Taken Before Connecting The Batteries.See Victron's book Wiring Unlimited for clarification on the 4 (and only 4) acceptable ways to parallel-connect batteries from your brief description it sounds like the batteries you just replaced were likely improperly connected, thus the premature failure of one. So long as the two batteries are properly parallel-connected, this is the best and only reliable and accurate way to do what you're trying to do: both the BMV and the MPPT require a single reference voltage to function properly, so trying to treat the batteries as separate even though they're not will net you nothing but trouble, inaccurate charging, and inaccurate capacity readings. The same goes for your proposed charging method: you should not attempt to connect a single solar controller to two separate batteries, but rather parallel-connect those batteries to form a single bank and then charge that bank as one.

This is definitely not the correct way to connect your system you should (properly) parallel-connect these two batteries to form one bank, which you will then be able to accurately monitor. It may be an overkill but am I going about this the right way? While I could monitor the bank with only 1 x BVM712, I want the ability to monitor each battery independently I would expect I need to set each 712 up as 240AH and will each one report correct SOC, Current Draw/Charge for each battery rather than as a battery bank? In the picture attached/below is how I believe I should wire up 2 x BVM712 and a MPPT100/20 so I can monitor each battery independently. I've since decided to replaced both batteries to be safe and now looking to add battery monitoring and solar charging as none currently exists in the boat. One of the batteries recently started to become very hot and was constantly drawing 16amps from the charger, upon removing and testing, it still reported plenty of CCA, Voltage and current draw were still good but the casing was showing signs of deforming from heat stress.

I have 2 x 12V 240AH AGM batteries wired in parallel that are used to start my starboard engine and also double up as the house batteries on my boat.
