I am working on an underwater RC vehicle. I want to have a large battery capacity so the vehicle runs for a long time. Unfortunately, I don’t have the space available for a large 5000mAh battery so I am resorting to using x4 individual 14.8 volt, 4s, 1400mAh batteries.
I know how to connect the batteries in parallel and use them, however I don’t know how to charge this large battery altogether. What I am trying to say is that I want to keep this large battery (made of 4 smaller batteries) together and be able to connect but also charge it in this configuration for ease of use. Other than the XT60 with power and ground, I know these batteries have cell equalizer connectors.
I would appreciate any guidance on how to charge this large 16s battery or ideas.
