Modify 4mm & 5mm bullet-type gold-plated connectors
Modify have introduced their new bullet-type 4mm and 5mm connectors. They are of a low-profile design to prevent interferences with low top decks and come pre-shaped for easy and reliable soldering. The heavy-duty four contact points design makes for improved power transfer compared to standard connectors and at 14mm length they are compatible with most tube-style battery packs.
