Is it possible to make a multi bay charger from individul charger units

We are a volunteer fire brigade and have a single brand hand held radio used across the state. Currently that means we have 13 individual chargers for the batteries we use, the company that makes the radios offer a six bay charger but at $616 which puts it out of our price range.

Using the individual chargers is it possible to create our own multi bay charger? And how do we calculate the transformer needed? Is it a simple task of rewiring and fabricating a new case or would their be additional electronics required.

Actually, post a picture of the nameplate of the chargers. That info would be more helpful.

Welcome to the forums from down under.

Radio companies may be a little different in your neck of the woods. Here, with the Motorola line of radios, the single chargers are stand alone slow chargers while the 6 gang rack charger is a fast charge system. Converting the singles to a rapid charge system is fairly complicated as battery parameters are monitored in a rack charger while they are not in a single charger.

Ultimately the single chargers are better for the batteries as the rack chargers tend to charge the batteries to a high heat level which shortens their life.

Usually the AC adapter is designed to slow charge the unit in 8-10 hours. Changing that supply can be bad for the batteries as most of the single chargers have no internal regulator for charging.
