Back in the day of NiMh cells, Reedy had a technology that increased cell voltage. And now it’s returned in a similar form for LiPo cells.
A 7.6 nominal voltage means that with a suitable charger, the battery can be safely charged to 8.7V (4.35V/cell). It is not a secret that more voltage equals more power, so there is no easier way to achieve a performance advantage than a higher charge voltage!
But even when the typical 8.4V (4.2V/cell) charging limit is enforced, the battery still offers a significant advantage thanks to a flatter discharge curve, which results in more voltage deeper into the race.
For those who race where approved batteries are required, 7.4V are available and feature the same discharge curve characteristics as the 7.6V versions.
Note: Versions built to ROAR/EFRA/BRCA/IFMAR specs are available.
