Batteries are charged in parallel and discharged in series

To prevent the second battery from running backwards or even being deep-discharged, make sure you balance the batteries before connecting them in series and running them to the load. A poor man''s semi-decent attempt to balance them would be to just put both batteries in parallel for a long time to transfer some charge from the full battery to the …
