Who should buy this?
Ideal for 1–2 BHK Indian homes, small offices, clinics, and solar-paired backup systems running on a 600VA–1 kVA inverter. If you're replacing a single 150Ah tubular battery, this is the direct upgrade.
Applications
Home backup
4–6 hours of typical home load (lights, fans, TV, Wi-Fi) on a single charge.
Solar storage
Pairs with 500W–1.5 kW rooftop solar inverters to store daytime generation for evening use.
Small commercial UPS
Reliable backup for billing systems, POS terminals, and small office loads.
Telecom edge sites
Compact backup for small cell sites and broadband distribution points.
Why lithium over lead-acid?
A single Athena 12.8V 100Ah pack outlives 4–6 tubular battery replacements over 10 years, weighs 60% less, requires zero maintenance, and is 95% efficient versus ~75% for lead-acid. On a per-kWh-delivered basis it's roughly 40% cheaper over its life.

Safety & BMS Technology
15+ Protection Layers
Over-voltage, under-voltage, over-current, short circuit, thermal runaway prevention.
Cell-Level Balancing
Active balancing keeps every cell uniform — extends real-world pack life.
Thermal Cutoffs
Over-temperature and under-temperature cutoffs to keep cells in their safe operating window.
Frequently Asked Questions
Will this work with my Luminous / Microtek / V-Guard inverter?
Yes — set the inverter to "tubular" or "lithium" mode (14.6V charge cutoff). We provide free setup guidance with every purchase.
How much backup will it give my home?
A typical 1–2 BHK load (~150–200W continuous) runs 4–6 hours. Add an AC and that drops to ~20 minutes.
Can I parallel two units for more capacity?
Yes — up to 4 packs in parallel, doubling capacity to 400Ah / 5.12 kWh.
