🇮🇳 Made in IndiaE-Bike Battery Load Tester in India – BCT-6 60A
60A Load · 12V VRLA Lead Acid · Pan-India Delivery
The BCT-6 is a 60A e-bike battery load tester for 12V VRLA lead-acid e-bike and electric scooter batteries (12–30Ah). Press the load button for 10 seconds and read the built-in digital voltmeter while the 60A load is still applied — under that load 10.0V and above is good, 9.6–9.9V acceptable, 9.0–9.5V weak, and below 9.0V means it has failed the test. ₹2,415 all-inclusive with COD, UPI, and free pan-India delivery in 3–7 working days from Samco Battery, Delhi (est. 2000).

How to Load Test an E-Bike Battery in 3 Steps
Clamp
Red lead to positive (+), black to negative (−) on your 12V VRLA battery.
Press & Hold
Hold the load button for ~10 seconds. Watch the digital voltmeter for a live reading.
Read & Decide
10.0V and above — good. 9.6–9.9V — acceptable. 9.0–9.5V — weak, recharge fully and retest. Below 9.0V — recharge fully, retest, and replace if it repeats.
12V E-Bike Battery Load Test Voltage Chart
| Reading at 10s under 60A load | Battery status | What to do |
|---|---|---|
| 10.0 V and above | Good | Battery is healthy — keep riding. |
| 9.6 – 9.9 V | Acceptable | Usable. Recharge fully and monitor monthly. |
| 9.0 – 9.5 V | Weak | Recharge fully, then retest. Plan a replacement. |
| Below 9.0 V | Failed | Failed the test. Recharge fully and retest; replace if it repeats. |
These are SAMCO's practical interpretation thresholds for a fully charged 12V VRLA battery tested with the BCT-6 for approximately 10 seconds, not an industry standard. Battery manufacturer specifications should take priority where available.
The same thresholds apply to every SAMCO 12V load tester. Full reference for 12V and 24V packs: Battery Load Test Readings Chart.

Who Uses the BCT-6 E-Bike Battery Tester
E-Bike & E-Cycle Owners
Check a 12V VRLA e-bike battery pack at home before a long ride, and find the one weak block dragging down range.
Electric Scooter & Scooty Riders
Diagnose sudden range drop on an electric scooter battery instead of replacing all four blocks blindly.
Two-Wheeler Service Centres
A 10-second load test per battery keeps workshop diagnostics fast during high-volume service days.
Battery Dealers & Retailers
Prove battery health at the counter and settle warranty claims with a load reading, not an argument.
Used E-Bike Buyers
Test every 12V block before paying for a second-hand e-bike — a battery set is the costliest part to replace.
Delivery & Rental Fleets
Screen an entire e-bike fleet monthly and retire failing lead-acid batteries before they strand a rider.
Frequently Asked Questions
How do I check my eBike battery health?
Clamp BCT-6 to your 12V VRLA battery, press the load button for 10 seconds, and read the voltmeter. 10.0V and above — good. 9.6–9.9V — acceptable. 9.0–9.5V — weak, recharge and retest. Below 9.0V — recharge fully, retest, and replace if it repeats.
Why does my eBike show full charge but die fast?
Your battery has surface charge — it reads full at rest but sags as soon as current is drawn. A 60A load test makes that sag visible, so you neither replace a battery that is still serviceable nor keep one that is not.
Can I test a 48V or 60V eBike battery pack with the BCT-6?
The BCT-6 is designed for one 12V VRLA battery at a time. A 48V pack is four 12V batteries in series and a 60V pack is five. Do not connect the tester across the complete pack. Testing individual 12V batteries should only be done after the series connections have been safely isolated, following the battery or vehicle manufacturer's procedure.
Will it work for my electric scooter?
Yes. Any 12V VRLA lead-acid battery between 12Ah and 30Ah is compatible — covering most Indian eBikes and electric scooters. Not for lithium-ion or LiFePO₄.
Can I use the BCT-6 on a lithium-ion or LiFePO₄ eBike battery?
No. The BCT-6 is designed only for 12V VRLA lead-acid batteries. Do not connect it to lithium-ion or LiFePO₄ batteries; their protection systems and electrical characteristics are different.
What voltage means my 12V eBike battery must be replaced?
Anything below 9.0V under a 60A load means the battery has failed the test — recharge fully, retest, and replace if it repeats. Between 9.0V and 9.5V the battery is weak — recharge it fully and retest before deciding.
How is a load tester different from a multimeter for eBike batteries?
A multimeter reads resting voltage only, so a dying battery can still show 12.6V. A load tester draws real current and shows what the battery does under strain. See the full comparison in our load tester vs multimeter guide.
Is COD available? What about UPI?
Yes. Both Cash on Delivery and UPI are accepted across India. Price ₹2,415 all-inclusive. Free delivery in 3–7 working days.
What is the warranty and return policy?
Manufacturer warranty with a 7-day return window. Full terms at samcobattery.in/warranty-return-policy/.
Is it suitable for workshops and service centres?
Yes. Heavy-duty clamps and a 10-second test cycle make BCT-6 ideal for high-volume diagnostics at two-wheeler service centres. Dealer and bulk pricing available on WhatsApp.
