Agree on theTP4056 boards, excellent value for money, I buy the TP4056/DW01
charge/battery protection boards in packs of ten these days as they're
really handy for throwing together a quick Li-Ion battery pack for portable
gear.

An example:

-Charger-Module-1A-18650

I've also found a variant which doesn't have the DW01 battery protection IC
but does have the TP4056 and a boost converter which can provide outputs up
to a claimed 12V/2A (I'm pretty sure it won't give 2A at 12V but it still
looks very useful)
