I recently had an issue with one of my Ikelite rechargers for my DS161 strobe battery packs.
The charger would work intermittently. Sometimes start and stop within minutes or say the battery pack is charged when it isnt. One time both the battery pack and the charger became hot to touch.
I could see this becoming a problem for someone who has only one charger (lucky I have two) and especially when on a trip.
I contacted my local Ikelite dealer (digital diver, Cairns) and they informed me that it is most likely the end plug of the charger which goes into the battery itself. It cost only a few dollars each and is simple to remove.
This solved the problem of my charger and thought that anyone with an Ikelite charger for the Ds125/160/161 battery packs that this would be an essential spare part.
