Beste,
Ik zou gaan voor de eerste opstelling. Alle batterijen mogen nog identiek
zijn, maar na verloop van tijd kan er altijd eentje sneller van
karakteristiek of inwendige weerstand veranderen dan de andere.
In de tweede schakeling kan die dan de overige 3 negatief gaan beïnvloeden
en eventueel deze 3 sneller doen ontladen. In de eerste schakeling staan er
meerdere in serie, waardoor dit effekt sterk zal verminderen.

Wat voor batterijen zijn het? Batterijen parallel en in serie is
vragen om problemen. Je kunt beter een hele rits in serie zetten (maar
niet teveel!) en dan met een schakelende voeding de spanning naar
beneden brengen of een aantal Li-ion accu's parallel (eventueel 2 a 3
cellen in serie) en dan de spanning met een schakelende voeding omhoog
brengen.
