Panasonic VW-VBT380 Rechargeable Lithium-Ion Battery Pack

The VW-VBT380 is the large-capacity pack in Panasonic's VBT battery family, rated by Panasonic at 3560mAh and 12.8Wh with a 3.6V output. It is the pack to carry when a shoot runs past what the supplied battery covers, on the consumer V and W series camcorders that take VBT packs.

It uses the same mount and charger as the smaller VBT packs, so a kit can mix capacities without adding a second charger. Panasonic sells it as a replacement and spare pack rather than a kit item.
