What it does

Three things every battery owner needs to know.

Whether you're running an e-rickshaw fleet or riding a single e-bike, Battery Connect covers the same three questions: is it safe, is it healthy, and how far will it actually go.

01

Lock it down with one tap.

Secure My Battery sets a Bluetooth password directly on your BMS. Once it's on, only your phone can read or change its settings — even if someone else gets physically close enough to try connecting. Your password is never shown to anyone else; it's simply remembered by your account so you're never locked out of your own battery.

Secure Your Battery
02

A full health check in under 10 seconds.

Run a Quick Check any time — Battery Connect reads cell balance, temperature, and every active protection flag on your BMS, then gives you a clear Pass, Warning, or Fail with the specific reason behind it. Every check is saved, so you've got a running history to catch problems before they become failures.

Test Your Battery
03

Real range, not the number on the box.

Watch live charge, voltage, current, and cycle count as you ride. The Range Estimator learns your actual energy use per kilometre from real trips, so the range it shows you reflects how you actually drive and load your vehicle — not a lab figure from the spec sheet.

Know Your Battery
How it works

No wiring. No separate tester. Just your phone.

1

Switch on Bluetooth

Battery Connect scans for any Smart BMS in range — no pairing codes or extra hardware required.

2

Tap to connect

Pick your battery from the list. It's saved for next time, so reconnecting later takes one tap.

3

See everything, instantly

Charge, voltage, temperature, cell balance, and protection status — live, the moment you connect.

More in the app

It doesn't stop at one health check.

Battery Connect keeps working for your battery even after you close the app.

🔗

Link My Device

Link a battery once and Battery Connect keeps reconnecting to it in the background — no need to open the app or tap connect every time.

🚨

Instant alerts

Full charge, low battery, high temperature, or a new fault — you get a push notification the moment it happens, even with the app closed.

🔋

Two BMS protocols, one app

Works with both JBD and Daly Smart BMS boards — the two protection boards found in most e-rickshaw, e-bike, and scooter packs today.

📱

Manage every battery you own

Save as many batteries as you like and switch between them in one tap — Battery Connect auto-connects to whichever linked battery is nearby.

🔐

Phone-verified account

Sign up with an OTP-verified phone number. Your battery passwords stay safely tied to your account, so you're never locked out.

📣

Direct updates from us

New features, tips, or offers — sent straight to your phone, with a saved history you can revisit any time in the app.
