We have checked internally and if everything works out, we could offer the linked battery again at the end of the month. Unfortunately without guarantee, as the supplier himself is waiting for delivery.

If you are willing to solder the connector to a T-connector (Deans) -no warranty- or make an adapter, there is a LiPo battery 7.4V 800mAh with the same dimensions from Absima, for example. One of these is in stock at Brack, but also from competitors.

But you don't have an alternative by chance?
