charging half AA size li-ions

i have these li-ions that are half of an AA size, so i can mod an AA light with a xhp-50 led and maybe a tir or fresnel.
but i’m not able to charge the da things. has anyone ever figured out how ??

Get one of the TP4056 charge boards from Mtnelectronics and ask rich to change the resistor for those cells (~10k) and add wires with magnets.

thank you very much superduck

Tarver, is there anything written on the battery’s wrapper?
