What Power Supply/battery to Use?

If you are using a mains adapter, then one that delivers 5V and at least 2A will be suitable. A suitable battery would be a 4 cell rechargeable NiCd or NiMH assembly delivering a nominal 4.8V. The mAh capacity needed depends on how this component is used and how long you want it to run before the battery needs recharging. It is the average consumption rather than the default or peak consumption which you need to consider. For example, using it for 5 minutes at a time at 1500 mA totals 125 mAh, and a 2000 mAh battery will supply 16 episodes before needing recharging. On the other hand if it is running continuously at that rate the battery will need recharging after just over 1 hour. Possibly, though, the high consumption is only for a few seconds, and the battery may last much longer.

Low Battery

When the battery is in seriously low condition, Lockly will make continuous beeping sounds in addition to the flashing low battery icon on the touch screen. You should replace batteries immediately to avoid your smart lock from shutting down. Low Battery: Battery Icon on the display keypad will light up to indicate low battery. Solution: Replace batteries immediately to avoid battery failure. Lockly can still operate up to 300 cycles in low battery condition. Dead Battery: When there is no display and no sound; screen is non-functional. Lock does not respond to app. Solution: Replace batteries immediately. Supplied physical backup keys can be used to unlock the door. Alternatively, use a 9V battery as shown below to temporarily activate the lock. Your Lockly will automatically detect battery polarity. So hold your 9V battery lead in place against bottom of the Lockly to temporarily activate the screen to enter your Access Code. Once unlocked, batteries should be replaced immediately.

Fishfinder & lights work off a battery?

It should be fine running the fishfinder and the motor off the same battery as long as it's charged when you head out. just test it out for a half day trip and see how much it drains it. My fishfinder actually has a meter that tells me how much of a charge is left on the battery. I actually run 3 batteries 1 for the motor and electronics and 2 for the trolling motor

Battery and lights flickering

It sounds like your alternator is not charging the battery correctly. With the engine running, check the charge. It should be at 13.5-14.2vdc when running properly. If the voltage is lower than that, and/or the voltage is continually dropping, the alternator is not charging. Take it to a local parts store and have it tested

Short to battery & short to ground

Any wire connecting to a sensor can touch or short with another wire that is battery positive ie 12V so the sensor is fed directly from the battery. What will the sensor do in those conditions? Fail open circuit or fail short circuit? If short circuit then will that cause a fire or damage to other wiring? Failing open circuit does not tend to cause wiring damage.If the sensor wire is shorting to the body or ground, i. e. battery negative then will that damage the sensor or other wiring or the unit supplying the sensor?All these need to be checked and accounted for, and fuses or current limiters need to be fitted as appropriate

Is it bad to recharge a severely depleted battery? Is it possible to overcharge a battery?

Batteries are little chemical engines. They fall apart for many reasons if severely depleted. They burn away and boil and and . if you try to overcharge them.But severely depleted. Does that mean 0 volts? or .1 volt or 1 volt. That's pretty severe. Lithium Ion batteries don't like being 1 volt. When they are . 5 volts, you can try all you want, but even if you bypass the computer charger, and actually get 4.1 volts, or 4.2 or 4.5 or 5. They are not really all there. Might be good for 10 minutes.Saying that, I had Nicads in my drill. I bought it zeons ago. When I charge my pair, and they both work the same way, they charge. actually pretty quickly. And last for about 4 minutes. Then back on the charger. They didn't like being severely depleted by just sitting there and self-discharging. They have not improved past that for the last year of use.Saying that, my son brought home a 12 Volt gel-cell battery that his quality control department had rejected as being too old, like 5 years on the shelf. I gave it the usual treatment, about 60 volts until some current charge showed. Then 16 volts for 8 hours, then discharge, then charge. and it now works not badly. About 1/4 the rated capacity. I must remember to charge it up again.They discharge a bit on their own.SO: Lithiums. very very temperamental.Nicads. horrible memory loss at depletion. Love overcharging if you can keep the temperature inside them down. Great Power. Heavy.Lead Acid. Their normal life is on a small overcharge forever. It's called 'maintenance". And they will take a lot of current after full charge, but will get hot. Boiling will kill it. The old fashioned refillable ones. just fill them up with water when they dry out. Did I mention the hydrogen generation on fast charging? Don't put the battery in a closed box at a high charging rate. Buy a good charger. Please. Matched to your exact battery.
