The battery is a Li-ion Japcell JC123R 3.7 V 650 mAh. It may not be cutting edge technology, but the battery has turned out to be able to provide power through my helplessly executed circuit to the Lister's motor and actually make the loco move. I consider that a success.
While I was shopping batteries I bought a BC-4123 charger as well. Battery and charger set me back 35 €. Not much for starting a gentle learning curve and should I continue using JC123Rs or other 16340 type batteries, the charger will see plenty of use.
'But if you have installed the battery permanently under your loco, how do you fit it in the charger' the attentive reader may ask. The battery is permanently fixed and it will not fit in the charger. To be able to charge the battery in the loco a socket is installed under the bonnet. A matching socket's two leads were soldered to a pair of crocodile clips. On one of the four stations in the charger I soldered small brass tabs on the contacts. I can now easily attach the crocodile clips to the tabs on the charger and charge the battery via the socket under the bonnet. May sound very old fashioned but it does really work.
