$465.00 (1fuse, Orion cable, case inspection)
$500 (1fuse, Orion cable, Thermistors)
$624.00 (1 fuse, Orion cable,Thermistors and Current Sensor)

Internal Fuse: A15QS400-4 Minimum, A15QS400-QS450, A30QS400-QS450 or A50QS300 are reasonable.
Integral Orion 36S cell tap cable installed. Length can be specified. Can be shielded with (split) flex conduit after shipping. (not shown)
CNC Serialization (inspection date and serial number) in final location.
Coolant slot 25% surface area was milled and has a protective chute on bottom that can be moved in emergency with a marginal amount of force.
Custom threaded busbar devices installed on fuse (underneath electrical tape) for optimal ring terminal surface area usage.
600v EPDM welding cable on outside for extra damage protection on power leads.
Power lead grommet hole increased in size so larger cables can be used on case.
Includes 1x paper copy of battery documentation.

Internal Fuse Mod 2
$275.00 (1 fuse, DB37 cable)(lid only)
$390.00 (1fuse, DB37 cable, case inspection)
$425.00 (1fuse, DB37 cable, Thermistors)
$549.00 (1 fuse, DB37 cable, Thermistors and Orion Current Sensor)

This is an alternative way to fix Junior Lonestar Packs so they are compliant with the recent rule changes.
Fuse is completely internal. A30QS400-4 fuse is default for Junior EV application.
This one shows the original DB37 female connector connected to a male DB37 terminated to a Orion BMS Cell Tap Cable.
CNC Serialization (inspection date and serial number) in final location.
Coolant slot 25% surface area was milled and has a protective chute on bottom that can be moved in emergency with a marginal amount of force.
All packs that run through our shop now are installed with 6-8 unterminated (shown in image) or Molex terminated thermistor cables so battery pack can be thermally monitored now.
This mod does not include price of Orion 36S>>>DB37 cell tap termination labor or Orion cable.
Current sensor meant to work with Orion BMS system.
