Two power units = unity power or Flexibility. In tandem 90 amperes charge rate
Separate:
a) Redundant safety factor. One fails the 2nd can take over
b) Individual voltage controls. Different batteries different temperatures.
c) Schottky rectifier isolates the units. No isolator no parallel operation*
d) Timer on one charger. Allows it to be absorbsion charger with time limit
e) When timer shuts off unit # 1, unit # 2 continues as a float charger no timer
So in essence if there is 6 cells of batteries, the Borg will charge them. Flooded, calcium, gelled, AGM. 12 hour timer can allow for a very big bank. Voltage set-point span 11.7 - 15.44
A voltage adjustment for each charger allows it to bulk charge or float anywhere I set it.
Set the voltage way way back. Start THREE HUNDRED WATT generator. Increase voltage just until generator starts to lug down. Must be increased every half hour. Or not.
Charge batteries 110F? No problem. -35F still no problem.
Important thing is when up to 12 hour timer runs down, 2nd charger set at float takes over automatically. Set it and forget it.
Weak Mexican power? Compensate. Turn voltage down to start off with then tweak up every so often.
*These power supply chargers can not work in tandem. One will shut down. The 500 ampere rated schottky is so huge it absolutely minimizes heat, and has a forward voltage drop of .17 at low or no load.

Timer charging is not critical when it comes to over charging. Who cares if the Borg absorbsion charger runs at 14.7 volts for one or five hours "too long"? The battery doesn't care. I don't care.
The BORG primary use is as a BATTERY CHARGER. Not a converter, inverter or perverter. It is incredibly flexible. And my 12 year old granddaughter works it just fine. She has started cars, charged the family fishing boat battery, then connected it to the Lifeline. Without an error or hesitation.
And Rashneesh the programmer, of Calcutta and the Lucky Dragon integrated circuit company had nothing to do with any of it...
