Todd chargers in 24 VDC systems [RE-wrenches]

[Richard Perez, Home Power magazine]

<x-flowed>Hello Wrenches

Anyone got any suggestions regarding hooking up two 12 Volt, 70 Amp 
Todd chargers to a 24 Volt battery (20 @ L-16s).

We (Joe and I) wired the outputs of the Todds in series and then to 
the battery connection in the power center. Heavy wire and short 
runs. We set each Todd for half of the voltage we wanted to regulate 
the battery at. We switched on the Todds (powered by Honda ES6500 
generator) and current output was way lower than we expected.

By juggling the voltage limit controls on the Todds we were 
eventually able to get current output of the Todds up to around 30 
Amps at 29 VDC. The stronger Todd we set up around 15 VDC and the 
weaker about 14 VDC.

Bottom line is we are getting about 60% of the wattage our of the 
series connected Todds as we got when they were wired in parallel 
into a 12 Volt battery.

Has anyone else run into this? Any fixes?

Richard
