Anderson SB175 Power Connector (shown in picture) or finger safe Radlock/Surlok Connectors

Includes internal fuse for short circuit or over-discharge. Fuse curve coming soon.

TE Connectivity CPC 37 Pin Panel Mount Connector ("Circular Plastic Connector", "Amphenol Connector", "Racing Connector").

Anderson power connector can be modified with an addon smaller SB50 parallel connection so it is easier to plug in chargers with SB50 output connector upon request.

BMS output end termination (after CPC connector) can be to an Orion BMS2 cable, a 37 Pin CPC Female, 6x JST-XH, 6x Polyquest balance taps, Ampseal or any other reasonable BMS connectors.

6 thermistor cables standard on 100v and 8 on 150v. 80 thermistors max is available with purchase of Orion Thermistor Expansion module.

As of December 2023, all new battery packs will have in built 25% surface area coolant ports on the lid 6-8 thermistor cables minimum, panel mount BMS output that can connect a BMS cable with a Orion BMS connector, a CPC Female connector, 6x6S JST/Polyquest taps, 40-pin Ampseal or any other reasonable balance connectors specified by customer. We no longer manufacture battery packs with the DB37 connectors or any permanent dangling cables. We only use panel mount connector hardware as of 2023 December. Halfscale EV Dragsters also have a metal case option. All the necessary CPC 37-Pin balancing cables are available.
