FAQ:  Can I charge multiple 12V batteries in series at the same time with one charger?  (i.e. 2 batteries for 24V, 3 batteries for 36V, etc…)

Answer:  Yes, it is possible to charge a battery pack consisting of multiple 12V batteries in series at the same time using one charger. However following needs to be observed:

1) The initial charge – you need to charge all the 12V batteries individually to full voltage level BEFORE you start using them together as a pack.

2) We strongly recommend to use some kind of management to make sure all the batteries are working within the proper operating voltage levels.  For example the Akumon may be used to monitor the status of the batteries.

Additionally we remind the need to observe the general instructions concerning the use of the 12V batteries.
