Dreamcast:Advanced Controller Board Mod
This mod board is installed on top of the original controller board which adds the following:
- Replacing original battery with Li-ion 18650 battery, with professional charging and protection circuitry. - Replaces all old components like capacitor, resistor, and fuse which is now re-settable fuse.
This battery board will solve the problem of CMOS time keeping issue once and for all. The used battery should give more than enough charge.
Our test showed charging the battery for an hour will charge its voltage up by about 70-100 mV which our tests showed this amount could be enough for more than 6 months!
As above figure is showing, the battery follows the typical discharge rate and it passed 6 months and didn’t even go below 4v. This means extremely long battery life especially knowing the battery tested was an old Chinese knockoff so using a good original brand will show even better performance.
