50 mm² battery links

 These 50mm² battery links are great for connecting battery strings together.

Sure beats making up your own. Hole diameter suits 8mm (or 5/16”) bolts, and distance between holes is 200mm. These links will fit most makes of L16 lead acid batteries.

Note: if wiring your own system in NZ, you can do so for voltages up to 120 VDC (ELV) if you have suitable knowledge and experience. For LV systems (>120 VDC) this is prescribed electrical work and it must be done by a licenced electrician.
