PylonTech FIDUS 51.2v 100Ah Lithium Battery:

The Pylontech FIDUS is the current-generation 51.2V low-voltage residential battery module in Pylontech’s line-up, built around LiFePO₄ (Lithium Iron Phosphate) cells for chemical and thermal stability. A single module stores 5.12kWh, with 4.86kWh usable at the standard 95% depth of discharge — and the official datasheet rates the platform up to 97% DoD in favourable conditions. What sets the FIDUS apart from a basic single-box battery is how far it scales: Pylontech specs the same module for systems from 5kWh up to 600kWh by combining anywhere from 1 to 120 modules, so the identical hardware covers a single-room backup circuit and a small commercial installation alike.

Electrically, the FIDUS is built for a continuous 1C discharge rate with a 2C peak for 15 seconds — meaning a single 5.12kWh module can comfortably push out short bursts well above its nominal rating to start motors, compressors, or other inrush-heavy loads. Communication runs over RS485 and CAN, and Pylontech lists compatibility with more than 50 hybrid inverter brands, so the module drops into most solar setups already common in Pakistan without special adapters.

Build quality is aimed squarely at harsh, humid or coastal conditions: the enclosure carries an IP65 rating and a C5-M anti-corrosion classification (the same category used for structures exposed to salty, industrial or high-humidity air), and Pylontech offers a Nordic version with cell-level heating that extends the safe charging window down to -20°C for installations in extreme cold. Mounting is flexible — wall, ground, or rack — and the module is backed by a 10-year design warranty at 25°C with a rated cycle life beyond 6,000 cycles.
