Hover to zoom. Take your battery holder and plug the ground or black wire to any ground on the Arduino. This is not a charging circuit. Since I am designing a battery for the Arduino, I will need to use two 18650 batteries in series. For a different trip point or battery sources, resistors and zeners can be changed. But I am Old and may forget and leave them connected. I just would like to install 2x18650s in parallel so 3.7V @5000x2 mAh approx. I guess for my purposes, the 1N4148 would be just as good. With the 5000mA batteries, it just means that it will run a long time before needing recharging. I have lost a few batteries but kind of doubt that it was from discharging them too far. Geeks may have noticed that Ive connected both comparators together with a pullup resistor. This will provide a nominal 7.4 Vdc and up to 8.5 Vdc when fully charged. Now if you're planning on selling these instruments you might be better off using the protected batteries. Good -- 9V battery clip with 5.5mm/2.1mm plug : ID 80 : $2.95 : Adafruit Industries, Unique & fun DIY electronics and kits. Total cost is less than $0.80. I don't think this design can be adapted to your needs. The 18650s are supposed to have 10 times less self discharge rate. (See Picture), http://www.ebay.com/itm/Battery-Charger-18650-Rechargeable-Li-Ion-3-6-3-7-/280638594652?pt=LH_DefaultDomain_0&hash=item41575d1e5c#ht_2522wt_952.

Lilypad Battery Holder:Each holds a single coin battery (CR2032 or similar) is integrated On / Off Switch,easy for turning off to save batteries. 10 years ago Snap a battery to the connector. The red wire should go to "5V" and the black wire should go to "Gnd". Well, Im pretty familiar with the Arduinos and most will work down to about 4 Vdc. I could just keep an eye on them and charge them often. There is an additional complication- the 18650s are made with or without protection PCBs which add something like a couple mm to the length. Okay, so Im a Geek and Im not really satisfied with the 6 AA battery setup. WARNING: Some of these modules are for charging batteries with the USB and some are for supplying 5V out of the USB connector. This will provide a nominal 7.4 Vdc and up to 8.5 Vdc when fully charged. As far as I can tell those DIY power banks include both the DC boost and the 18650 recharge circuit in them!! So I decided to design a comparator that would shut off voltage to the Arduino if one battery drops to about 3 Vdc or both batteries drop below 6V. ******************************************************************************************. However the resistor values will have to be adjusted. I just need to be able to recharge my built-in batteries via USB, I don't want the end user taking out and switching batteries all the time, instead just charge via laptop usb or usb phone charger. If either of these happens it will disconnect power going to the Arduino. This actually works as the outputs are called open collector. It is ideal for all types of DIY projects, Raspberry Pi, Automobile, Camera and outdoor Camping DIY installations. This will provide a nominal 7.4 Vdc and up to 8.5 Vdc when fully charged. 1 4xAA Battery Pack Holder Case Box to DC Barrel.
