For a number of years I've been trying
to come up with a low cost plug for the BA-5590/U family of batteries
and now have a working prototype.
This is larger than the planned size because it's has a lot of jumper
options to allow making about any type of cable you can think of, for
- 12 Volt output (shown)
- 24 Volt output
- 24 Volt Charging
- 12 Volt Charging
- 4 wire output (two wires for each battery side)
- Dual voltage split output. Three wires, +12, gnd, -12
The next version will have a dedicated PCB for "12 Volt Output" and another for "24 Volt Output".
