Keep the inverter. Change the battery.
Going lithium usually means replacing the whole system. X One doesn't: it is a universal LiFePO4 battery that works with any existing lead-acid or lithium-based inverter, so the expensive half of your setup stays exactly where it is.
-
Your inverter stays. No new unit, no rewiring, no electrician rebuilding the wall.
-
Free installation. We take the old battery out and put this one in.
-
No acid, no fumes, no vented battery box in a room you live in.

Built-in safety
A smart BMS guards every cell against overheating and overcharging, around the clock.

Inside X OneA-grade LiFePO4 cells
Premium cells, and a brain to look after them.
Lithium iron phosphate is the chemistry that holds its capacity instead of fading. The BMS is what keeps it that way — watching every cell, all the time.
- Chemistry
- A-grade LiFePO4 prismatic cells
- Cycle life
- 4,000 cycles at 80% depth of discharge
- Efficiency
- 94%, against 60–80% for lead-acid
- Capacity held
- 70% at the end of five years. Lead-acid is under 50% at three
- Protection
- Advanced BMS — overheating, overcharge, cell balancing
- Size & weight
- 60% smaller and about 28 kg, against 50–60 kg
Match the rating to the battery you have now.
If you are replacing a single 12V lead-acid battery on a home inverter, the 100Ah 12.8V is the one. Not sure? We will confirm it on a callback.
A 100Ah lithium delivers roughly what a 150Ah lead-acid does, so the rating you need is usually smaller than the one you are replacing. No-cost EMI from ₹1,834 a month.
The same job, done two very different ways.
Backing up your home, by a battery that needs looking after and one that does not.
| Parameter | Lead-acidWhat you have now | Lithium X OneUniversal LiFePO4 battery |
|---|---|---|
| Life | 3–5 years | 3× the life, up to 10 years |
| Charging time | 9–12 hours, overnight | 3× faster — about 3 hours |
| Efficiency | 60–80% | 94% |
| Maintenance | Requires water top-ups | Zero — sealed unit |
| Rating needed | 150Ah for 400W over ~3 hrs | 100Ah does the same work |
| Size | Bulky | 60% smaller |
| Weight | 50–60 kg | About 28 kg |
| Safety | Leakage, acid spills, overcharging | Advanced BMS, sealed |
| In the home | Minor gas emissions | No leakage, no fumes |
| Backup at higher loads | Falls away as the load rises | Holds under higher loads |
| At 5 years | Under 50% of capacity by year 3 | Still holding 70% |
Pay more once, or pay again every three years?
The lithium premium is real. So is the fact that you buy a lead-acid battery again, and again, inside the life of one X One.

The best battery is the one you forget you own.
No jug of distilled water on the shelf. No smell in the room it sits in. No note in your phone about checking the levels before the monsoon. It just holds the evening up, year after year, and asks for nothing.

Common questions.
Will Lithium X One work with my current inverter?
Yes — that is the point of it. X One is a universal battery designed to work with any existing lead-acid or lithium-based home inverter. You keep the inverter and the wiring; only the battery changes.
If you would like it confirmed against your exact model before you order, tell us which inverter you run on a callback and we will check it.
Which rating should I pick?
Match it to the battery you are replacing. The 100Ah 12.8V suits most homes running a single 12V inverter, and the 150Ah 12.8V is for longer backup in a bigger home. A 24V setup wants the 100Ah 25.6V.
Worth knowing: a 100Ah lithium does roughly the work of a 150Ah lead-acid, so the rating you need is usually smaller than the one you have.
Is lithium worth the higher price?
It costs more once. A lead-acid battery is typically replaced three or four times inside the life of one X One, so the premium comes back in replacements you do not buy — before counting the maintenance you stop doing and the charging time you stop waiting through.
No-cost EMI starts at ₹1,834 a month if you would rather spread it.
Does it really need no maintenance?
No water, no topping up, no checking levels. It is a sealed unit with a BMS watching the cells, so there is nothing on your side to do. There is also no acid and no gas emission, which is why it is safe to keep in a room you actually use.
How fast does it charge?
About three hours to full — roughly three times faster than the 9 to 12 hours a lead-acid battery takes. In practice that means it is ready again before the next cut rather than the next morning.
