Re: [FTC]: [FTC] Samantha and batteries

If I were wiring up a Tetrix Robot, I'd still use the Samantha Alternate Method. I would put it after the Switch so it's the first item powered before any Controllers or a Power Distro Board. Instead of crimps, I would use Anderson Powerpoles for quick connect swapping. Teams using this setup have been able to drive with 4.018 volts.

I've seen many Samantha's in this configuration. The only issue I've seen related to electrical was where a First Gen Samantha's ESD protection was broken and led to power cycling. If you use the correct guage wire, proper connections and at your discretion and legality per the rules a fuse, then your Samantha should have power, be protected and be ok.

If the grounds get that broken up, then you're involved in a match were everything has gone wrong. I've only seen this happen once where a team burnt out a motor controller and two motors. Extreme ESD played a factor here. In fact, If you have not already, I would say read the document Addressing NXT Lockups. Once you combine all the information in the Wiring, Samantha and Lockup Documents, you should be able go ahead and wire up the robot.
