This is a digital capacity meter built for 36V, 13-series LFP battery packs — it reads pack voltage and displays remaining charge so you know your state of charge at a glance without pulling out a multimeter.
A capacity meter is a small part with an outsized job: it's the number you glance at before you trust a pack to carry a load. Matching the meter's cell-count and chemistry calibration to your actual pack is what makes that number mean anything. 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.
Critical Fitment & Requirements
- Configured for 36V nominal battery systems.
- Built for 13S (13 series-connected cell) pack architecture.
- Calibrated for LFP (Lithium Iron Phosphate) discharge curves.
- NOT compatible with 48V 16S packs or other non-36V voltage systems.
- NOT accurate for non-LFP chemistries (NMC, lead-acid, or similar).
- NOT compatible with packs having a cell count other than 13S.
Key Benefits
- Purpose-built calibration for LFP voltage-to-capacity curves, not a generic universal meter.
- Digital display for quick state-of-charge reads without a separate meter.
- Matched cell-count configuration reduces reading drift versus mismatched meters.
- Compact form factor suited for direct pack integration.

FAQ
Is this meter rated for 48V systems?
No. This meter is configured specifically for 36V 13S LFP packs. It is NOT rated for 48V 16S systems or other voltage configurations.
Will this work with non-LFP battery chemistries?
No. This capacity meter is calibrated to LFP voltage curves. It is not accurate for NMC, lead-acid, or other lithium chemistries with different discharge curves.
Does this meter fit any 13-cell battery pack?
It is designed for 36V 13S LFP packs specifically. Cell count and chemistry both need to match for the displayed capacity to be accurate.
What SKU do I order for this meter?
The part number is MTR010, priced at $20.00. There is a single configuration available for this meter.
