Frequently asked questions

Match the voltage first: the pack must have the same system voltage as your vehicle’s controller — 48 V, 60 V or 72 V for most scooters, 51 V, 61 V or 64 V for e-rickshaws. Then choose capacity (Ah) for the range you need: more ampere-hours means more kilometres per charge. The mobility calculator works this out from your motor rating and daily distance.

Add up the watts of what you want running during a cut and multiply by the hours you need. The battery must store that much energy, and it must match your inverter’s battery input voltage (12 V or 24 V for most homes). The load calculator does the arithmetic and recommends a battery from the range.

It is the most thermally stable lithium chemistry, lasts thousands of charge cycles, needs no maintenance and weighs far less for the same energy. Every pack carries a battery management system that balances the cells and protects against over-charge, over-discharge, short circuit and over-temperature.

One rated for your pack’s charge voltage — never a charger built for another voltage or another chemistry. Each EV battery page lists the Trontek chargers that match it, and the cart suggests them when you add a battery.

UPI, credit and debit cards, net banking and wallets, through Razorpay. Paying by UPI takes ₹200 off the order. Card EMI is available at the payment step on your card issuer’s terms. Payment is taken online when you place the order.

Do not pay again straight away. A failed payment that was debited is reversed to the same account automatically, usually within 5–7 working days and often sooner. If your order shows as paid within 30 minutes, nothing more is needed. The payment failure policy explains the full process.

WELCOME1000 for ₹1,000 off a home inverter battery, and WELCOME2000 for ₹2,000 off a 3-wheeler or e-rickshaw battery. Enter the code in your cart. One code per order, once per customer; the UPI discount applies on top.

A product that arrives damaged, faulty or not as ordered is replaced or refunded — report it within 48 hours of delivery with photos. Unused products in their original sealed packaging can be returned within 7 days of delivery. Refunds go back to the original payment method within 5–7 working days of approval. The refund policy has the details.

Yes, free of charge until it is dispatched — call customer care with your order number. Once dispatched, refuse the delivery or follow the return process instead. A cancelled prepaid order is refunded in full to the original payment method.

Yes. Enter your GSTIN at checkout and the invoice is issued against it. Every order receives a GST invoice regardless.

Use the Track order page with your order number and the phone number on the order, or open the order from your account.

Standard delivery is free on orders above ₹4,999. Below that a flat delivery charge applies and is shown in the cart before you pay. Batteries ship in protective crates at no extra charge.

Only where the product page says so. EV packs are fitted by your vehicle dealer or mechanic; home batteries connect to a lithium-ready inverter. If you are unsure, call customer care before ordering.

It is stated on every product page, in the manufacturer’s own words — for example 3 years or 1200 cycles on the LiEV e-rickshaw packs, and 5 years or 4000 cycles on the Powercube home batteries, whichever comes first.

Register a complaint with your order number and the battery’s serial number, or call a warranty number on the support page. You get a reference number and the claim is handled with Trontek.

None. Keep it dry and away from direct heat, charge it with the matching charger, and do not open the casing — opening it voids the warranty.
