BTB-1 IS a mysterious project. IT SIMULATES retriggerable, back-to-back monostable circuits. TRIGGER USES an inherent fact of comparator design, the delay ascribed as being asserted when logic becomes briefly contentious, instable. I use it as the trigger. Two stages retrigger each other during momentary instability with small capacitively coupled spikes, barely enough to cause runaway & a trigger which cannot occur with direct DC coupling between stages. NOW, IT has occurred to me that I should look for a way to assert THREE back-to-back stages. IF PODSIBLE, the third would allow for an EXECUTION period, analogous to the 'data valid' duration in digital bus clocking. After SYNC, & DELAY, there could be the EXECUTION period to assert intended results from logical & event confluence. NEXT TRIGGER would synchronize. BTB-1 is demonstrated in very low frequency clocking.

Stored wattage can be estimated using the amp-hour rating.
I decided that knowing 12 volts X 1 amp for 180 minutes is a rating pertinent to calculating stored energy in watts.
Assume a .1 volt drop resulting from testing the battery charged at 12 volts delivering current through 12 ohms for a duration of 180 minutes. Power lost from the battery is 12 x 180/60 = 36 watts.
It is then assumable the battery will perform in like manner through a linear range of the discharge period when in use. Thus for a deep cycle battery charged to 13.5 volts the available power in watts is estimated as:
10 x (13.5 - 11.5) x 36 = 720 watts
