What actually breaks e-rickshaw batteries in Bihar — waterlogging, heat, voltage fluctuation and long rural routes — and how to choose a lithium-ion pack that survives it.
A short routine, done every day, catches almost everything that turns into an expensive failure — and most of it takes less time than waiting for the first passenger.
Most lithium packs in India die early because of how they are charged, not because of what they are made of. These seven habits cost nothing and change the arithmetic.
Lost range is usually blamed on the battery, and the battery is often innocent. Work through these five layers in order before you spend money on a new pack.
At 45°C ambient, a battery pack in direct sun is working well above its comfortable range. Here is what heat does to a lithium pack, and which precautions are worth the trouble.
A battery pack is a chain of cells in series, and a chain is only as strong as its weakest link. Understanding balancing explains most of the odd behaviour drivers report.
Ah, V, kWh, C-rate, DoD, IP67, BMS. A plain-language guide to the numbers on an Indian battery spec sheet — and which of them actually predict how the pack will behave.
The instalment is the number everyone compares, and it is the wrong one. Here is what to read on a battery loan document, which charges people miss, and what protections you already have.
A lead-acid set looks cheaper on the day you buy it. Here is the simple calculation that tells you what each option actually costs you per kilometre over three years.
