Lithium Battery Price in India 2026: 12V, 24V and 48V Price List
A 100Ah LiFePO4 lithium battery in India costs roughly ₹27,000 for a 12.8V unit, ₹54,000 for a 25.6V unit, and ₹1,08,000 for a 51.2V unit as of July 2026 — because price scales with the total energy stored, not with the amp-hour number on the label. This guide gives the complete published price list for Nexus Solar Energy lithium batteries, explains what actually decides a lithium battery's price, and shows how to pick the right voltage for your inverter.
Every price on this page is the published MRP, inclusive of tax. Nexus publishes prices openly on each product page — there is no "call for price".

Why Does a 100Ah Battery Cost Twice as Much at Double the Voltage?
Because "100Ah" alone does not describe how much energy a battery holds. Energy is voltage multiplied by amp-hours:
| Battery | Calculation | Energy stored |
|---|---|---|
| 100Ah at 12.8V | 12.8 × 100 | ~1.28 kWh |
| 100Ah at 25.6V | 25.6 × 100 | ~2.56 kWh |
| 100Ah at 51.2V | 51.2 × 100 | ~5.12 kWh |
A 51.2V 100Ah battery stores four times the energy of a 12.8V 100Ah battery, so it costs roughly four times as much. When comparing prices across brands, compare price per kWh, not price per amp-hour — that is the only comparison that means anything.
What Actually Decides a Lithium Battery's Price?
Two components inside the box account for nearly the entire cost difference between a cheap battery and an expensive one:
1. The cells. Cell cycle rating is the single biggest cost driver. A 3,500-cycle cell and a 6,500-cycle cell look identical from outside the case, and the price difference between them is substantial. This is why a suspiciously cheap "6,500 cycle" battery deserves scrutiny — the number should be verifiable, not just printed.
2. The BMS. A basic hardware BMS with fixed settings costs a fraction of a smart BMS with active cell balancing, temperature sensing, RS485/CAN communication and an LCD cycle-count display. Both are legitimate products for different needs — but they are not the same product at the same price.
Everything else — the casing, terminals, wiring — is a small share of the cost. If two batteries of the same voltage and capacity differ sharply in price, the difference is almost always in the cells, the BMS, or both.
12.8V Lithium Battery Price and Uses
A 12.8V 100Ah LiFePO4 battery stores about 1.28 kWh and is the entry point into lithium storage in India, priced from ₹27,187.
Best suited to: small inverters up to about 1kW, single-room backup, solar street lighting, and DC applications. Also the standard choice for replacing a single 12V lead-acid battery.
What to check: whether the BMS cut-off voltages match your existing inverter. A 12V inverter that discharges to 10.5V and charges to 14.5V needs a battery whose specification matches, or a configurable smart-BMS battery.
Nexus 12.8V options: a Premium-series unit at ₹27,187 (5,000 cycles, 5-year warranty*) and the DEVSOL unit at ₹31,624 (15-year warranty*).
25.6V (24V) Lithium Battery Price and Uses
A 25.6V 100Ah LiFePO4 battery stores about 2.56 kWh, priced from ₹54,374.
Best suited to: 24V inverters in the 1.5kW–3.5kW range — the most common home inverter class in India. This is the voltage most Indian households with a hybrid inverter will need.
What to check: the BMS current rating against your inverter's peak load. A 100A BMS supports 100A of continuous draw; exceeding it puts the battery into protection and shuts the inverter down. That is the protection working, not a fault — but it means the battery bank must be sized to the inverter, not below it.
Nexus 25.6V options: an ECO-series unit (3,500 cycles) and a Premium-series unit (5,000 cycles), both at ₹54,374.
51.2V (48V) Lithium Battery Price and Uses
A 51.2V 100Ah LiFePO4 battery stores about 5.12 kWh, priced from ₹1,08,749.
Best suited to: 48V hybrid inverters from 5kW upward — larger homes, shops, clinics and small commercial installations. At these power levels 48V is the engineering standard, because the same power at half the current means thinner cables and lower losses.
What to check: whether the battery communicates with your hybrid inverter over RS485 or CAN. At this system size, inverter-battery communication is what delivers full rated backup and full rated life.
Nexus 51.2V options: a display model at ₹1,08,749 (5,000 cycles) and the Pro model at ₹1,35,700 (6,500 cycles), both with live cycle-count LCD display.
Which Voltage Should You Choose?
| Your inverter | Battery voltage | Typical Nexus MRP from |
|---|---|---|
| Up to 1kW | 12.8V | ₹27,187 |
| 1.5kW – 3.5kW | 25.6V | ₹54,374 |
| 5kW and above | 51.2V | ₹1,08,749 |
The rule that saves the most money: match the battery bank capacity to your inverter capacity, never below it. A 2.5kWh battery on a 4kW inverter will cut off under heavy load — and the buyer will blame the battery.
Expanding later: Nexus lithium batteries support up to 16 units in parallel, so a bank can start at one battery and grow with your load without replacing what you already bought.
Is a Lithium Battery Cheaper Than Lead-Acid Over Time?
On day one, no. Over the system's life, usually yes — and the reason is replacement count.
A lead-acid battery typically needs replacing every 3–5 years. A LiFePO4 battery rated for 3,500 cycles, used once daily, runs for roughly nine to ten years; at 5,000 cycles, closer to thirteen. Over a ten-year period, that is one lithium purchase against two or three lead-acid purchases plus the labour and disposal each time.
The honest caveat: this maths only holds if the cycle rating is real. That is why a battery that can display its own cycle count is worth more than one that cannot — the number stops being a claim and becomes something you can check.
What Nexus Publishes on Every Battery
Nexus Solar Energy manufactures LiFePO4 batteries in Bulandshahr, Uttar Pradesh, supported through a 1150+ dealer network. Published on every product page: capacity, voltage, cycle life, warranty, BMS type and MRP.
To be precise about certification: Nexus holds BIS registration for its solar panels (IS 14286, Licence R-93046086) and hybrid inverters (IS 16221 and IS 16169, Licence R-93035050). It does not hold a BIS licence for lithium batteries and does not claim one.

Frequently Asked Questions
What is the price of a 100Ah lithium battery in India?
As of July 2026, a 100Ah LiFePO4 battery costs approximately ₹27,000 at 12.8V, ₹54,000 at 25.6V, and ₹1,08,000 at 51.2V. Price scales with stored energy — a 51.2V 100Ah battery holds four times the energy of a 12.8V 100Ah battery.
What is the price of a 12V 100Ah lithium battery?
Nexus 12.8V 100Ah LiFePO4 batteries are priced from ₹27,187 (5,000 cycles, 5-year warranty*), with the DEVSOL model at ₹31,624 carrying a 15-year warranty*.
What is the price of a 24V lithium battery for an inverter?
A 25.6V (24V) 100Ah LiFePO4 battery from Nexus is ₹54,374, available in ECO-series (3,500 cycles) and Premium-series (5,000 cycles) versions. This voltage suits inverters in the 1.5kW–3.5kW range.
What is the price of a 48V lithium battery?
A 51.2V (48V) 100Ah LiFePO4 battery from Nexus starts at ₹1,08,749 with an LCD display model, and ₹1,35,700 for the Pro version rated at 6,500 cycles. This voltage suits hybrid inverters of 5kW and above.
Why are lithium batteries so expensive compared to lead-acid?
The cells and the BMS account for most of the cost. Lithium cells rated for thousands of charge cycles cost far more than lead-acid plates, and a smart BMS with active balancing, temperature protection and communication adds further. The trade-off is replacement frequency — one lithium battery typically outlasts two or three lead-acid batteries.
How long does a lithium battery last?
It depends on the cycle rating and daily usage. At one full cycle per day, a 3,500-cycle battery runs roughly nine to ten years, a 5,000-cycle battery about thirteen, and a 6,500-cycle battery around seventeen. Batteries that display a live cycle count let you verify this rather than trust it.
Which lithium battery is best for a home inverter?
Match the voltage to the inverter: 12.8V for inverters up to 1kW, 25.6V for 1.5kW–3.5kW, and 51.2V for 5kW and above. Then check that the battery bank capacity is at least equal to the inverter capacity, and that the BMS type suits your inverter — configurable smart BMS for modern hybrid inverters.
Can I connect two lithium batteries together?
Yes. Nexus lithium batteries support up to 16 units connected in parallel, which lets you start with one battery and expand the bank later as your backup requirement grows, without replacing the original battery.
