Hi, I have a 36V trolling motor and plan to run 3 x 12V Lithium batteries in series and use a 3 outlet 12/30 ac to dc charger when I get home to charge.
Is there an easy way to connect and disconnect between series and hooking up the 12 v charger to each of the 3 batteries please?
I used to have a 36V system on my boat, but switched to 12V. Previously, I had an Orion 12-48V isolated DC-DC converter that sent 48V to a 100/20 MPPT configured for 36V. This setup worked really well. You can also use the new Bluetti Charger 1, a universal MPPT power supply for 12V-24V input to output up to 56V and plug that into the 100/20 MPPT.
If you want to charge it with a 3x12V configuration, you could use a series connection with single Anderson-style connectors. You might only need a 75A rating: https://www.jaycar.com.au/75a-anderson-powerpole-connector-set/p/PT4407?srsltid=AfmBOopEoVbA00nFSwKzPeOnvoYgCqmlZewzIAlLUJINlWsvzUvxhmdY
Install a 50A Anderson plug on each battery ± to connect the charger. This allows you to break the series connection and then plug in 3x50A charging leads from the charger.
Hi, I also am setting up the same system. Am wondering if I can use 3x 12v blue smart chargers connected to each battery individually. Unsure if I can do this without actually separating the batteries from the series connection
