This is a little off topic but there are times when you can get away
with cells connected in parallel under heavy load - your Newt will not
come close to providing the required load for this to be even a remotelyi
good idea.

Charging in series is fine, with one proviso -they must all be matched
cells. Generally this means brand new, identical cells permanently
wired before even the first charge. Difficulties arise when series
charging different cells, or identical cells that have had different
amounts of use.
