Brand new, never installed.
This is the VPH 850 and is complete with SAE posts and also with a remote reset switch.
The VF lithium batteries are complete with internal BMS that provides fault protection and isolation.
For more details see the VF website.
They dont seem to have the VPH850 listed right now but its the same as VPH750 but with better specs.
My cost was well over $1,000
Asking for $800 +shipping
