Sega Nomad 18650 Lithium Battery Pack
Warning: If your Nomad System has a 5v input mod (LCD 5v mods are safe and not part of this warning) this battery pack may damage your Nomad! This pack is designed as a replacement for the original and supplies 7.2-8.4v this is equivalent to the 6 AA batteries that was intended to power this console. In a 5V system mod you change the power path by installing USB Ports or other 5v input sources that could potentially allow the battery contacts to energize the 5v rail with battery voltages that are potentially damaging to the system. As there is no way for us to account for all types of mods of this type we can not guarantee your console's safety in the event of use of this product and Laser Bear Industries is not responsible for damage that could result.
Custom battery pack for the Sega Nomad which will hold two 18650 Lithium Ion batteries for a maximum of 3500 mAh of juice.
The Lithium Cells are not included with this pack you will need to source them. They need to have a tab and on cell protection is highly recommended.
18650 cells will max out at 3800mAh if you find one that says anything higher than that number it is fake and will not come close to that amount of storage. Expect to pay around $22usd per battery for 3500mAh cells if they are less than $10 they are also likely to be fake.
My recommended cells are Nitecore nl1835hp which can be purchased directly from its manufacturer here.
Outside of the Nitecore cells look for cells meant to be used in flashlights or vaping equipment, these cells typically have a tab and are internally protected. Just remember if it says 8000mAh it is fake and likely only 1000mAh in capacity.
Another tested 3500mAh cell that is a bit more reasonable in price is this one
Once batteries are installed you need to initialize the pack, this is done by supplying power to the power input. This must be done every time batteries are removed, the included charge and protection board has a low voltage cutoff to prevent over discharge of the cells, they require power from the charging side in order to enable the battery voltage to flow into the system.
Depending on the mods done to your Nomad and the capacity of the cells you install into the pack you may see up to 6+ hours of play from a single charge. Charging is done from a normal Nomad PSU, or any Sega Genesis Model 2 PSU. Charging will depend on the capacity of the cells, but should not take more than 5h to complete. There are no indicators on this pack to tell you they are at capacity, but when in use the Nomad will display low battery when it needs to be charged. You may charge the pack while playing on the system, just plug into the pack and continue playing, this will however take longer to charge the cells as the Nomad will be taking some of the power from the charging.
This is offered as a kit which you assemble yourself or preassembled. To build a the kit please follow the directions found in the guide video.
