This is a battery capacity meter for BigBattery Raptor 2 systems. It displays charge level and voltage, and it uses a shielded connector to resist electrical noise. It works with 36V and 72V Raptor 2 batteries only.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Product Overview
A capacity meter is a small but important part of any Raptor 2 setup. It gives you a direct read on charge state and voltage, so you're not guessing at how much run time you have left. This matters most in the field — on a golf cart, an off-grid cart, or any mobile Raptor 2 application where you need a quick, reliable glance at battery status before you head out.
Device Characteristics
- Type: Battery capacity/voltage meter accessory
- Compatible Voltage Range: 36V and 72V systems
- Connector: Shielded connector
- Compatibility: Works with all Raptor 2 battery models
Wiring & Configuration Limits
This meter is designed to read directly from 36V or 72V Raptor 2 battery packs. It is not a standalone battery monitor for other battery chemistries or brands, and it is not rated or documented for series/parallel battery bank configurations outside the Raptor 2 platform. Do not attempt to wire this meter into a non-Raptor 2 battery system — connector compatibility and voltage display accuracy are not verified outside this product line.
Pro-Installer Tip
Loose or corroded shielded-connector pins are the most common cause of erratic voltage readings on capacity meters like this one. A meter that jumps around under load isn't just an annoyance — it hides a true state-of-charge picture, which can lead you to over-discharge the pack without realizing it. Before final installation, seat the shielded connector fully and check for a firm click, then verify the reading against a known-good digital multimeter at rest. On any Raptor 2 pack, treat readings below 20% remaining capacity as your working reserve limit, not your target — consistent deep discharges below that point shorten pack life even on lithium systems built for high cycle counts.
Key Benefits
- Direct charge-level display for quick field checks
- Voltage display for more precise state-of-charge assessment
