TAD300 UAV Balancing Charger product render

SCROLL

Three smart channels. Charge three packs at once — up to 300W per port, auto-start on connect.

Per-cell equalization. Every cell is monitored and balanced, so aging cells never hide inside an average.

Built for the field. Rugged body, active cooling, and storage mode to park packs safely between missions.

Live channel monitoring

Fleet status,
at a glance.

Each port reports its own state — voltage, current, delivered capacity and elapsed time — on a screen your ground crew can read without a manual.

Up to 300W per channel — 15A / 26V (900W total on DC)
8 chemistries: LiPo · LiHV · LiFe · Li-ion · LTO · NiMH · NiCd · AGM
Auto-start on connect · AC/DC dual input (DC 7–32V)
60W USB-C PD 3.0 port for field laptops & phones

Per-cell equalization

Equalize every cell.
Fly longer.

The TAD300 carries a 1.6A balancer on every channel — double the usual 0.8A — balancing each cell individually, not just the pack, so aging cells stop hiding inside an average. Watch six cells converge:

TAD300 MCU — ARM Cortex-M4 32-bit core processor

1–240Interrupts, plus NMI
12-cycleInterrupt latency

Battery maintenance

Discharge & store.
Safely.

A built-in 0.1–3.0A discharge circuit keeps every pack healthy between sorties — bleed down to storage voltage, re-balance cells, and park batteries so they're mission-ready when you are.

Discharge 0.1–3.0AProgrammable per channel

Storage modeHold packs at safe voltage

Auto cutoffStops at target voltage

Longer lifeLess capacity loss in storage
