12V Lithium Battery Prices
The 12V lithium battery is the most common entry point for Indian homeowners upgrading from lead-acid. At a nominal voltage of 12.8V, a single LiFePO4 cell block replaces a traditional 12V lead-acid battery while delivering significantly more usable energy.
12.8V 100Ah — The Standard Home Backup Unit
A 12.8V 100Ah LiFePO4 battery stores 1.28 kWh of energy and supports 80% depth of discharge (DoD), giving you roughly 1.02 kWh of usable power per cycle [Explained]. This is enough to run 4 ceiling fans and 10 LED lights for approximately 4–5 hours [Explained].
Price landscape:
- Exide Livo 12.8V 100Ah: ₹18,000–₹26,000 depending on retailer, Bluetooth-enabled BMS for app monitoring, 5-year warranty [3rd-Party Retailer]. The Exide Livo is one of the most affordable branded options, though cycle life data varies by retailer listing.
- Luminous Helios 12.8V 100Ah: ₹39,999, 3000 cycles, 5-year warranty [Manufacturer Spec]. Luminous commands a premium for its established service network across India.

A 12.8V 200Ah unit stores 2.56 kWh, roughly double the 100Ah variant. These are used in larger homes or setups requiring overnight backup for essential loads. Pricing typically ranges from ₹45,000 to ₹70,000 depending on brand and BMS features [3rd-Party Retailer].
Use Cases for 12V Lithium
12V lithium batteries are ideal for small to medium homes with a single solar inverter rated up to 1500VA. They are plug-and-play replacements for 12V lead-acid batteries — no wiring changes required. For homes with 2kW+ solar panels and higher inverter capacity, moving to a 24V or 48V system is more efficient [Explained].
24V Lithium Battery Prices
A 24V (nominal 25.6V) lithium battery is built by connecting two 12.8V LiFePO4 blocks in series. This configuration doubles the voltage, which means the inverter draws half the current for the same power output — reducing wire thickness requirements and transmission losses [Explained].
25.6V 100Ah — The Mid-Range Choice
At 25.6V and 100Ah, you get 2.56 kWh of stored energy with approximately 2.05 kWh usable at 80% DoD. This suits homes running a 2kW–3kW inverter with moderate loads.
- Loom Solar CAML 25.6V 100Ah: ₹64,375, wall-mount form factor, 3-year warranty [3rd-Party Retailer]. Loom Solar’s pricing is transparent and published on their website, which is unusual in a market where most brands require dealer quotes.
Most other brands — Luminous, Exide, Livguard — offer 24V lithium options in the ₹55,000–₹75,000 range, though exact pricing requires contacting authorized dealers [3rd-Party Retailer].
When 24V Makes Sense
A 24V system is the sweet spot for Indian homes with 2kW–3kW solar arrays and inverter capacity between 1500VA and 3000VA. It balances cost and efficiency — cheaper than a 48V setup but more efficient than 12V for medium loads [Explained].
48V / 51.2V Lithium Battery Prices
The 48V segment (nominal 51.2V for LiFePO4, using 16 cells in series) is where serious solar storage lives. A 51.2V 100Ah battery stores 5.12 kWh — enough to power a typical Indian home’s essential loads (fans, lights, refrigerator, TV) for 8–12 hours [Explained].
51.2V 100Ah — The Home Solar Standard
This is the most popular configuration for residential off-grid and hybrid solar systems in India. Prices vary significantly by brand, cycle life, and communication protocol:

51.2V 200Ah — For Heavy Loads and Commercial Use
A 51.2V 200Ah battery stores 10.24 kWh — suitable for large homes, small offices, or commercial installations running air conditioning and heavy appliances.
- Loom Solar CAML 51.2V 200Ah: ₹1,90,000, wall-mount, 5-year warranty [3rd-Party Retailer].
- Dyness PowerBrick 51.2V 14.3kWh (280Ah): 8000 cycles, 10-year warranty [Manufacturer Spec]. The Dyness PowerBrick is a premium, high-capacity unit designed for commercial and large residential installations. Its 8000-cycle rating is among the highest available in India.
Why 51.2V, Not 48V?
You will see both “48V” and “51.2V” used in the market. The difference is cell count: 48V typically refers to a 15-cell LFP configuration, while 51.2V uses 16 cells. The 16-cell (51.2V) design provides better voltage stability and is the preferred standard for modern hybrid inverters [Explained]. Always check your inverter’s supported battery voltage before purchasing — do not mix voltage standards.
Lithium Titanate (LTO): High-Cycle Chemistry
Lithium titanate (LTO) replaces the graphite anode in conventional lithium cells with lithium titanate spinel. This chemistry delivers significantly higher cycle life and faster charging compared to LFP, but at a higher cost per kWh. Nexus Solar Energy manufactures LTO cells and packs for applications requiring very high cycle life and fast charge capability [Explained].
Cycle Life: LTO vs LFP
LTO cells typically achieve 15,000–20,000 cycles at 80% depth of discharge, compared to 3,000–6,000 cycles for LFP under similar conditions. This means an LTO battery can last 3–4x longer than an LFP battery before capacity degrades to 80% of its original rating [Measured]. For daily cycling applications like solar self-consumption, this translates to 20–30 years of service life for LTO versus 10–15 years for LFP.
Charge and Discharge Speed
LTO cells can be charged at 5–10C rates (full charge in 6–12 minutes), while LFP cells are typically limited to 0.5–1C rates (1–2 hour charge time). This makes LTO suitable for applications requiring rapid charge recovery, such as backup power systems that need quick replenishment after a discharge event [Explained].
10-Year Cost Per Cycle
Despite LTO’s higher upfront cost (typically 2–3x the price per kWh of LFP), the 10-year cost per cycle can be lower due to the extended cycle life. For a system cycling once daily over 10 years (3,650 cycles), an LFP battery with 4,000-cycle life would need replacement once, while an LTO battery with 15,000-cycle life would last the full decade without replacement [Explained]. The actual breakeven point depends on the specific battery prices, cycle frequency and electricity tariff.
When to Choose LTO
LTO is best suited for off-grid systems, commercial installations with high daily cycling, and applications where fast charging is critical. For typical residential solar storage with 1–2 cycles per day, LFP remains the more cost-effective choice [Explained].
How to Choose the Right Lithium Battery
Selecting the right lithium battery involves five key factors:
1. Voltage Match Your Inverter
Your battery voltage must match your inverter’s rated battery voltage. A 48V inverter requires a 48V (51.2V) battery. A 12V inverter requires a 12V (12.8V) battery. Mixing voltages will damage both the battery and inverter [Explained].
2. Capacity Based on Your Load
Calculate your critical load in watts, multiply by the hours of backup you need, and divide by the battery voltage and usable DoD. For example: 800W load × 5 hours backup = 4,000Wh. At 80% DoD on a 51.2V system: 4,000 ÷ (51.2 × 0.8) ≈ 98Ah — a 100Ah battery is sufficient [Explained].
3. Cycle Life Determines True Cost
A battery that costs less but delivers fewer cycles will cost more per kWh over its lifetime. The Nexus Pro at ₹1,35,700 with 6500 cycles delivers a lower cost per cycle than a cheaper battery with 3000 cycles [Explained]. Always compare ₹/kWh delivered over the battery’s rated cycle life, not just the sticker price.
4. Warranty Length and Service Network
A warranty is only as good as the manufacturer’s ability to honour it. Established brands like Luminous, Exide, and Livguard have extensive service networks across India. Newer brands may offer longer warranty periods but have fewer service centers [Opinion]. Verify that the warranty covers capacity degradation — some warranties only cover manufacturing defects, not gradual capacity loss.
5. BIS Certification
The Bureau of Indian Standards (BIS) has notified lithium-ion cells and batteries under the Compulsory Registration Scheme (CRS). BIS CRS registration under IS 16046 (Part 2):2018 applies to manufacturers and importers — it is the registration holder’s obligation, not the consumer’s, to ensure compliance [Explained — sourced from MeitY Electronics and IT Goods (Requirement of Compulsory Registration) Order, 2021]. For consumers, the practical takeaway is to buy from brands that can show a valid BIS CRS registration number on the product or packaging. This is a reasonable quality signal, though it is not a guarantee of performance or cycle life.
Lithium vs Lead-Acid: Cost Comparison
The upfront price of lithium is higher than lead-acid, but the total cost of ownership over 10 years tells a different story.
| Factor | Lead-Acid (Tubular) | LiFePO4 Lithium |

| Cycle life | 300–800 cycles [Explained] | 3,000–6,500 cycles [Explained] |
| Replacement cycles in 10 years | 4–8 batteries [Explained] | 1 battery [Explained] |
| Maintenance | Periodic topping up, ventilation needed [Explained] | Zero maintenance [Explained] |
| Weight | 30–35 kg per 100Ah [Explained] | 10–12 kg per 100Ah [Explained] |
| Cost per kWh delivered (10-year) | ₹28–₹45/kWh [Explained] | ₹8–₹15/kWh [Explained] |
A lithium battery pays for itself within 3–4 years compared to lead-acid when factoring in replacement costs and usable capacity [Explained]. Over a 10-year period, lithium delivers 60–70% lower cost per kWh of stored energy.
