To wire the battery system, remove any loose items from both bins and place two 12 V dry cell AGM car batteries in the “Camera system” bin and four 12 V dry cell AGM car batteries in the “DVR system” bin. When placing the batteries, ensure the negative terminal is always facing the same direction. Note: A third battery may be added to the “Camera system” bin if the system is not maintaining an optimal charge during operations. Wire the two 12 V dry cell AGM car batteries in the “Camera system” bin in parallel. Attach the 3/8 in. ring terminals from the positive, 2 ft. wire to each of the two positive battery terminals on the 12 V dry cell AGM car batteries. Repeat this step with the negative 2 ft. wire with 5/16 in. ring terminals and the negative battery terminals.Attach the OSS/OSR wire from the charge controller to a positive battery terminal. Repeat this step with the negative OSS/OSR wire and the negative battery terminal on the opposite battery. Wire the four 12 V dry cell AGM car batteries in the “DVR system” bin in parallel (). Make sure that the four 12 V dry cell AGM car batteries are oriented in a 2x2 fashion. When looking into the bin, the side of the bin where the charge controller is attached is considered the top. As a result, the batteries in this 2x2 pattern will be labeled top left (TL), top right (TR), bottom left (BL) and bottom right (BR).Attach one 3/8 in. ring terminal from the positive 2 ft. wire to the positive battery terminal on battery TR and the other 3/8 in. ring terminal from this same wire to the positive battery terminal on battery BR. Repeat this step with the 5/16 in. ring terminal from the negative 2 ft. wire to the negative battery terminals on the respective batteries.Attach one 3/8 in. ring terminal from the positive 2 ft. wire to the positive battery terminal on battery TL and the other 3/8 in. ring terminal from this same wire to the positive battery terminal on battery BL. Repeat this step with the 5/16 in. ring terminal from the negative 2 ft. wire to the negative battery terminals on the respective batteries.Attach one 3/8 in. ring terminal from the positive 2 ft. wire to the positive battery terminal on battery BL and the other 3/8 in. ring terminal from this same wire to the positive battery terminal on battery BR. Repeat this step with the 5/16 in. ring terminal from the negative 2 ft. wire to the negative battery terminals on the respective batteries.Attach the OSS/OSR wire from the charge controller to a positive battery terminal. Repeat this step with the negative OSS/OSR wire and the negative battery terminal of a different battery.

Mechanical and electrical properties comparison between conventional and QTCC button batteries. (A) Experimental setup used to test the threshold force beyond which QTCC button batteries will conduct in SIF. Compressive force and voltage are measured in real time. (B) Schematic diagram of a QTCC button battery compressed below and above the σ_c and when the circuit is completed, achieving V_max. (C) A dry conventional button battery conducts at V_max with low applied stress, as highlighted by the dashed lines, showing the compressive stress at which the battery first achieves conduction (σ_c). (D) When immersed in SIF, a conventional button battery shows a ∼20% reduction in conduction voltage because of the short-circuit current leaked via the conductive fluid connecting the anode and cathode as an alternate conduction pathway. (E) V_max is reached at ∼58 N/cm² by a QTCC button battery in dry conditions. The V_max is equal to that of a conventional button battery. (F) Immersed in SIF, QTCC button batteries require similar levels of compressive stress to achieve conduction. In addition, the V_max achieved is indistinguishably different from that in the dry state because of the waterproof design of QTCC button batteries.
