LiFePO₄ packs that replace tubular lead-acid without the water top-ups, the fumes or the shed life. 90% usable capacity, smart BMS protection and a five-year warranty.
LiFePO₄ packs for home and office inverters in 12V, 24V and 48V, at 105Ah and 210Ah. Ninety percent of the rated capacity is usable, the smart BMS protects every cell, and there is nothing to top up or maintain — so the same battery is still doing its job years after a tubular set would have been replaced. Five-year warranty across the range.

Need a different voltage, capacity, footprint or terminal layout? We build inverter packs to specification for dealers, integrators and commercial installations — standard models are a starting point, not a limit.
Talk to our team →A backup battery earns its keep in the few hours a month the power is out. Six things we build in so it works then, year after year, with nothing asked of you in between.
VoltBee inverter batteries are available in 12V, 24V and 48V, in 105Ah and 210Ah, giving 1.34 kWh up to 10.08 kWh per pack. All models use LiFePO₄ chemistry.
It depends on your inverter’s voltage, the appliances you want to run and how long you need them to run for. Match the pack voltage to the inverter first, then choose capacity from your daily backup requirement. Send us your inverter model and load list and we will size it for you.
In most cases yes, provided the inverter supports lithium charging voltages or can be set to them. The pack voltage, charging profile and cable terminals need to be matched correctly — check with us or your dealer before switching.
LiFePO₄ packs deliver far more charge cycles than tubular lead-acid, which is why VoltBee inverter batteries carry a five-year warranty. Actual life depends on how deeply and how often the pack is cycled.
No. There is no distilled water to top up, no acid to check and no terminal corrosion to clean. The pack can be installed indoors without the ventilation a lead-acid battery needs.
Ninety percent of the rated capacity is usable, so a 24V 105Ah pack gives roughly 2.4 kWh of delivered energy. Dividing that by your running load in watts gives an approximate backup time, before inverter losses.
Yes. LiFePO₄ is the most thermally stable of the common lithium chemistries, and every pack has a smart BMS protecting against overcharge, over-discharge, over-current, short circuit and temperature limits.
Charging follows the CC/CV method at a recommended current of up to 0.25C, with a maximum of 50 A. A pack charged at the recommended rate takes roughly four hours from empty, depending on the charger and the inverter.
The price depends on voltage, capacity and order quantity. Contact VoltBee with your inverter details and backup requirement for the right configuration and current pricing.
Tell us your inverter and what you need to keep running, and we’ll size the right pack and point you to your nearest dealer.
