Looking for a Tattu or Herewin Alternative in India? An Indian-Made Comparison

Published: June 2026 · By: Leolus Energy Engineering Team · Read time: 8 min

Key Takeaway: Imported LiPo packs like Tattu and Herewin are the default for many Indian drone operators — but the import lead times, forex-linked pricing, and lack of local support are real costs. An Indian semi-solid state battery removes those frictions while improving on energy density and thermal safety.

Why Indian Operators Look for an Alternative

Tattu (Grepow) and Herewin are well-known LiPo brands, and they earned that reputation. But for a commercial fleet operating in India, importing batteries carries friction that has nothing to do with the cell itself: shipping windows measured in weeks, customs clearance, GST and import duty, currency swings that move your unit cost between orders, and the practical reality that technical support sits in another country and timezone. When a battery question stalls a deployment, "we'll hear back in a few days" is expensive.

That's why more Indian drone manufacturers and DaaS operators are evaluating a domestic alternative — not just to save on import overhead, but to get a battery built and supported locally.

Imported LiPo vs Indian Semi-Solid State — Side by Side

This is a general technology comparison, not a claim about any specific imported product variant. Always validate against your platform's exact discharge and weight requirements.

Where a Semi-Solid State Battery Genuinely Helps

  • Agriculture spraying: Daily high-temperature operations in the field benefit from lower thermal risk and stable cycle life. See our agriculture drone battery guide.
  • Surveillance & mapping: Higher energy density means longer endurance for the same weight budget.
  • Heavy-lift & delivery: 12S configurations deliver the voltage headroom heavy platforms need. Compare in our 6S vs 12S guide.

Is Switching Worth It?

For a one-off hobby build, an imported pack is fine. But if you run a fleet, build drones as an OEM, or depend on predictable supply and cost, an Indian-made battery changes the economics: you remove import lead time and forex risk, you get local engineering support, and — if you claim PLI benefits — domestic sourcing counts toward your value-addition. The right move is to validate a Nexfly pack against your current imported battery on your actual platform, then compare total landed cost and lead time, not just sticker price.

Frequently Asked Questions

Yes. Leolus Energy's Nexfly Series is an India-made alternative to imported Tattu LiPo packs. It uses semi-solid state technology for higher energy density and lower thermal risk, is dispatched from Bangalore in days rather than weeks, and is priced factory-direct in rupees with local engineering support. Validate a Nexfly pack against your platform's discharge and weight requirements before switching a full fleet.

For commercial UAV use, semi-solid state offers higher energy density (up to ~350 Wh/kg) and a more thermally stable electrolyte than conventional LiPo, which matters in India's high-temperature operating conditions. LiPo still has a place for ultra-high-burst hobby applications, but for endurance, safety, and cycle life on commercial platforms, semi-solid state is the stronger choice.

It depends on volume, but the savings are usually in total landed cost rather than just sticker price. Imported packs carry shipping, customs duty, GST, and forex variation; a domestic pack is priced in rupees with no import overhead and far shorter lead times. For fleets and OEMs, the reduced downtime from faster supply and local support often matters as much as the unit price.

In most cases, yes. Leolus Energy designs custom Nexfly packs in 4S, 6S, and 12S configurations from 11,000mAh to 40,000mAh, and can tune voltage, capacity, connector, and BMS to match your platform.
