Start an OEM projectAum Parsana is the founder of Halovolt Systems and leads its technology and product work. Aum writes Halovolt's buying guides on lithium battery prices, sizing and battery life, and its case studies on the cargo e-rickshaw, solar storage and forklift projects. Halovolt designs and builds LFP and NMC lithium battery packs in Rajkot, Gujarat.
Writes about lithium battery pack design, LFP and NMC battery packs, battery management systems, power electronics, telecom lithium batteries and EV batteries.
The battery pack design process step by step, for anyone commissioning a pack in India: the brief, cell choice, a worked series and parallel calculation, BMS, cooling, enclosure, testing and certification.
What AIS-156 covers, what Phase 1 and Phase 2 of Amendment 3 require of a battery pack, who tests it, and which documents a buyer should ask to see. Written from the amendment's own text.
BESS stands for battery energy storage system. This guide explains the parts, how to size one from load and hours, and what dated Indian cost figures do and don't tell a business.
Tubular and lithium solar battery prices read from makers' own sites on 4 November 2026, in rupees per rated and usable kWh, with GST, backup hours and what PM Surya Ghar covers.
What LFP (LiFePO4) and NMC batteries are, how they compare on energy density, cycle life, thermal runaway, cost per kWh and cold charging, and which suits home, solar, telecom, EV and forklift use.
A side-by-side look at lithium and tubular inverter batteries using makers' own datasheets: energy, weight, cycle life, warranty, cost per kWh and fitting lithium to your inverter.
Dated prices for 48V and 51.2V e-rickshaw lithium batteries in India, worked out per kWh, with lead-acid set prices, GST, PM E-DRIVE support and a buying checklist.
Scooter makers in India don't publish replacement battery prices. This guide shows what public numbers reveal, from Hero Vida's battery rental gap to online 48V and 60V listings.
India has little commissioned lithium-ion cell capacity, so most battery makers build packs from bought-in cells. See who makes cells or packs, where, how much capacity and each plant's status.
A lithium battery's life is counted in charge cycles. How many years those cycles last depends on depth of discharge, heat and charge level. LFP and NMC compared.
What 48V and 51.2V 100Ah lithium batteries cost on makers' own sites on 1 November 2026, with rupees per kWh, GST and the specs that change the price.
Prices for 12V and 24V lithium inverter batteries from makers' own sites on 1 November 2026, with price per kWh, GST, tubular prices and cost per kWh delivered.
A step-by-step way to size an inverter and battery for a shop or small office, with sourced appliance watts, three worked examples, and when a UPS or a mains socket is the better choice.
A step-by-step way to pick the inverter and battery that suit your home: load in watts, VA rating, 12V or 24V, battery size, and tubular or lithium, with 1BHK to 3BHK examples.
LFP vs VRLA for telecom towers in India: what TEC 67030 requires, whether a 48V pack needs 15 or 16 cells, and how to size a lithium battery bank for a site.
EV mobility
Challenge: Lithium packs that fit the battery space of new cargo e-rickshaws used for parcel delivery.
Solution: Custom-size 60.8V 132Ah LFP packs based on the Gati Cargo 132, with a 5-vehicle pilot before the fleet.
Solar & C&I storage
Challenge: A new anodizing plant with no backup power, on a grid with frequent outages.
Solution: Two Vidyut 240 LFP cabinets (96 kWh) with 150 kWp of solar, chosen over a diesel genset.
Material handling
Challenge: Battery swaps between shifts and a spare lead-acid battery for each of 40 three-shift forklifts.
Solution: 80V 400Ah LFP packs in a modified tray, on chargers that talk to the BMS, charged once a day.
