Hi guys,
would like to pick your brains if that is ok.
A neighbour has asked me if I could kindly get this old rc working, he had no charger so I tried to put some life into the battery. And after putting it onto charge using terminal clamps, the battery started making a quiet popping sound.
I have found the replacement batteries online, however I’m not sure if I’m charging the battery in a safe manner.
Any help would be appreciated.
