HA12 is an energy transfer battery equalizer with voltage display on mobile phone,
which can be used for 2-12V  batteries in series or in parallel to keep battery bank voltage balance.

When battery banks are in charging/discharging/free status, batteries voltage will
have difference, which may cause one of batteries fail prematurely.
