Battery Cells · LFP 3.2 V · 100 / 314 / 588 Ah

From one 314 Ah cell
to a 10 MW block.

Prismatic LiFePO4 cells, integrated into TOBOR-engineered packs, racks and containers. Fourteen 314 Ah cells make a 44.8 V pack; 252 make an 806.4 V rack; twenty racks fill a 5.06 MWh CTX container. Commercial MTX systems from 30 kW run on the 100 Ah cell.

How 314 Ah cells
become megawatt-hours.

The 250 kW–10 MW range is built on one LFP cell, 3.2 V · 314 Ah, wired in series into TOBOR-engineered packs and racks. Each CTX rack carries its own 125 kW PCS module and is managed by the in-house TOBOR BMS.

Three LFP cell platforms

The right cell for each power band.

Commercial cabinets need modest, runtime-sized energy; utility containers need the most energy per rack. We match the cell to the job.

Chemistry choice

Why LFP, not NMC.

Phones and EVs use NMC because energy density matters more than cycle life. A stationary battery cycling daily in Indian summer needs cycle life and thermal stability first.

Safe in 45°C summers

LFP chemistry is far more thermally stable than NMC. In May heat, that margin — plus liquid cooling in CTX containers — keeps the system clear of thermal runaway.

Built for daily cycling

~6,000 cycles on the 100 Ah platform and ~8,000 on 314 Ah, versus NMC's typical 2,000–3,000. Lower cost per delivered kWh for arbitrage and peak shaving.

No cobalt, no nickel

Iron and phosphate chemistry. No cobalt supply-chain exposure, and a simpler end-of-life story for stationary storage.

Where the cells go

Cells, counted per system.

From a 30 kW commercial cabinet to a 10 MW utility block — here's what's inside.

100 Ah · runtime-sized

MTX · 30–60 kW

Commercial cabinets for MSMEs, clinics and hotels. Battery energy is sized to the backup duration you need.
314 Ah · 1P → 8P strings

PTX · 250 kW–2 MW

819.2 V strings: 257 kWh at 250 kW up to 2.06 MWh at 2 MW for factories, campuses and HT consumers.
5,040 × 314 Ah

CTX-5000 · 2.5 MW

20 racks of 252 cells in one 20 ft liquid-cooled container — 5.06 MWh with a 125 kW PCS per rack.
20,160 × 314 Ah

CTX-B20 · 10 MW

Four containers, 80 racks, 20.26 MWh behind a 33 kV RMU — for utilities, DISCOMs and IPPs.

Questions and answers

Which battery cells does TOBOR use?
All TOBOR systems use prismatic LiFePO4 (LFP) cells integrated into TOBOR-engineered packs. Commercial MTX systems (30–250 kW) use 3.2 V 100 Ah cells (~6,000 cycles). PTX systems from 250 kW to 2 MW and CTX containers use 3.2 V 314 Ah cells (~8,000 cycles). The long-duration CTX-6600 container uses 588 Ah cells.
How are 314 Ah cells built up into a container?
Fourteen 314 Ah cells in series form a 44.8 V pack (14S1P). Eighteen packs make a 252S1P rack at 806.4 V and 253.2 kWh, each with its own 125 kW PCS module. Twenty racks — 5,040 cells — fill a CTX-5000 container at 5.06 MWh / 2.5 MW, and four containers form the 10 MW / 20.26 MWh CTX-B20 block.
Why LiFePO4 instead of NMC?
TOBOR uses LFP for stationary storage. Compare the specified cycle life, operating-temperature limits and protection provisions for each system. Chemistry alone does not determine safety or lifetime; installation, thermal management, depth of discharge and duty cycle all matter.
Does TOBOR manufacture its own cells?
No. TOBOR sources LFP cells and integrates them into TOBOR-engineered packs, racks and containers, managed by the in-house TOBOR BMS and EMS. Cell selection, pack and rack design and system integration are TOBOR's.
Can I buy cells, packs or racks separately?
Contact TOBOR battery sales with your requirement. We quote packs, racks and spares for TOBOR systems and integrators on request; complete systems are sized from your power, duration and site conditions.
