PowerDiag vs CellLog

PowerDiag は、PowerDiag Bluetooth アダプタ（別売）と組み合わせて、電動工具のバッテリーパックの状態を詳しく読み取る診断アプリです。 セル電圧・温度・容量・残量・充電回数などをその場で確認でき、劣化やセル間の電圧ばらつき（不均衡）を見える化します。中古バッテリーの状態チェックや、現場での簡易診断に最適です。 ■ 主な機能 ・各セルの電圧をグリッド表示、電圧差（不均衡）も自動計算 ・パック電圧／残量（SOC）／温度をまとめて表示 ・型番・容量・充電回数・製造情報を自動認識 ・読み取り履歴を端末内に保存 ・日本語／英語／中文に対応 ■ 対応バッテリー ・マキタ XGT ・HiKoki（マルチボルト 36V など） ※対応バッテリーは順次拡大予定です。 ■ ハードウェアが必要です 本アプリのご利用には PowerDiag アダプタ（別売）が必要です。お持ちでない場合も、設定の「デモモード」からサンプルデータでアプリの動作をお試しいただけます。 ■ プライバシー 本アプリは一切のデータを収集・送信しません。読み取った情報はすべて端末内にのみ保存され、オフラインで動作します。

CellLog is a per-pack logbook for LiPo, LiHV and Li-ion batteries. Track every pack you own — cycles, internal resistance, swelling and storage voltage — and retire packs on data, not guesswork. MADE FOR RC, FPV, DRONE & AIRSOFT Whether you fly quads, planes and helis, drive RC cars or run airsoft AEGs, your packs age with every charge. CellLog keeps one clean record per battery, so you always know which pack is fresh and which is on its way out. BATTERY REGISTRY - Register each pack: chemistry (LiPo / LiHV / Li-ion), cell count, capacity, C-rating, purchase date, baseline IR - See your whole fleet at a glance with health badges: Healthy, Watch, Retire CYCLE COUNTER - Tap "+1 Cycle" after each charge - that is all it takes - A cycle gauge fills toward your retirement limit, one colored block per log - Session logging: back from the field, tick every pack you used and add +1 cycle to all of them in one tap HEALTH CHECKS - Log internal resistance per cell, swelling and storage voltage - IR trend chart shows rising resistance before the pack lets you down - Full log history per pack, with delete for wrong entries RETIRE SIGNAL - Set your own rules: cycle limit and IR rise limit - CellLog flags packs to watch and packs to retire - with the numbers to back it up NFC TAGS - Stick an NFC tag on a battery, link it once, then tap to open that pack instantly - Write tags right from the app YOUR DATA STAYS YOURS - Everything is stored on your device - no account, no cloud, no tracking - Export your full logbook to CSV anytime CellLog is free for up to 3 packs.
