As a follow on to this thread .: https://forum.allaboutcircuits.com/threads/1-5v-aa-li-ion-rechargeable-battery-discussion.210283/
I am looking at using the LI-Ion 18650's for higher voltage/low density purposes in portable applications.
Any experiences?

Some, what's your issues?

Like all multi-series packs, correct charging and balancing is crucial. Another key issue, particularly for high discharge or fast charge regimes, is temperature management, both in terms of monitoring and physical layout/spacing.

 

All battery packs seem to be a compromise of some sort! First, compact size versus temperature control, then power delivery versus temperature rise/control. And always the challenge of cost versus performance.

 

What sort of current are you looking for?

 

Around 3 amper/hour.
