Stop wondering which battery has the lowest IR or whether a pack was put into storage mode. In 2 seconds trackside, scan vinyl QR stickers, track per-cell internal resistance, log maintenance notes, and balance fleet wear so you always race with maximum punch.
From the pit table to the driver stand with zero friction.
Print high-density DIY vinyl QR sticker sheets directly from your browser (or use 4-char visual IDs like K8W2). Stick them onto your 2S, 4S, or 6S packs.
1-tap camera scan in under 2 seconds. Instantly toggle between Charged, Used, or Storage (3.85V) status and auto-log race cycles right at the track.
Record cell IR (mĪ©) from your charger, automated AāF health grades flag voltage sag before qualifiers, and log timestamped maintenance notes per pack.
Say goodbye to storage charge confusion, faded Sharpie numbers, and mid-race voltage sag.
Leaving LiPos fully charged at 4.20V ruins cell chemistry and causes swelling, while over-discharging destroys capacity. When packing up Sunday night, it's easy to forget which packs are safely at storage voltage (3.85V/cell) and which are still fully charged.
1-tap Charged, Used, and Storage status toggles with instant visual confirmation every time you scan.
A single high-IR cell causes severe voltage sag under high amp draw. Your car feels sluggish off corners and drops top speed down the main straight in the crucial final 2 minutes of an A-Main.
Per-cell IR tracking with proactive degradation warnings and letter health grades so you only put low-resistance punch packs on the grid.
4 identical shorty packs look the same on your pit mat. Sharpie numbers rub off from tyre traction additive, motor cleaner spray, brake cleaner, and sweaty fingers.
Durable vinyl QR stickers and clean 4-character visual shortcodes (K8W2) that never wash off or fade.
When a battery takes unusually long to balance charge, runs hot after a run, or survives a hard chassis impact, you forget which pack it was by next weekend's race meet.
Dedicated timestamped maintenance notes diary attached to each pack to log balance times, temps, puffing checks, and resoldered leads.
Crafted trackside to eliminate Sharpie notes, guessing games, and mid-race power cutoffs.
Assign vinyl QR code stickers or 4-char shortcodes (e.g. K8W2) to every battery pack in your fleet for instant identification.
Record cell-by-cell internal resistance (mĪ©) and State of Charge. Detect failing cells before voltage drop hurts your lap times.
Keep a timestamped maintenance diary on every pack. Log cell balance times, temp checks, puffing inspections, and track incident notes.
Instantly toggle packs between Charged, Used, and Storage (3.85V) directly from the pit table or camera scan view.
Automatic Least-Recently-Used rotation recommendations ensure all LiPo packs experience balanced cycle distribution.

Nice work adding your first pack! Here is how to track its lifecycle at the track:
Charged (scan Charged QR or toggle manually) when a pack is charged, and log cell IR values.
Used (scan Used QR after run or toggle manually) to update status.
Storage (scan Storage QR at end of race day or toggle manually) to mark it at storage voltage.
Analyze Health: Tap the battery card below anytime to view its historical health grade (A/B/C) and IR trends!

CYCLES
Add baseline cycles for batteries purchased second-hand. Total cycle count and health grade will recalculate immediately.
Log a cycle after you complete a run or heat on the track. This increments total cycle count and tracks internal resistance (IR).
