R612       *Electrical system must be inspectable. All power regulating devices (per R505), associated wiring, and all fuses must be visible for inspection.

R613       *No high voltage allowed except for LEDs. Any active electrical item that is not an actuator (specified in R501) or power regulation device (specified in R505) is considered a CUSTOM CIRCUIT. CUSTOM CIRCUITS shall not provide regulated output voltages exceeding 5V, except if solely used for powering LEDs, but may pass through unregulated battery voltage.

R604       *Charge batteries at a safe rate. Any battery charger used to charge a ROBOT battery may not be used such that it exceeds a 3-amp average charge current. Follow all manufacturer recommendations when charging batteries.

R618       *Do not modify critical power paths. CUSTOM CIRCUITS shall not directly alter the power or control pathways between:
