The shift from lead-acid to lithium is no longer just a trend; it is a technical necessity for efficient energy management. Traditional lead-acid batteries suffer from significant voltage sag and can only be discharged to 50% without damaging their internal structure.
In contrast, Jarrett’s Lead-to-Lithium batteries provide:
100% Usable Capacity: We do not take away any capacity like lead-acid does. You get to use 100% of the rated capacity of our lithium batteries.
Longer Lasting: Expect up to 6,000 cycles from our JREK deep cycle battery series which represents up to 15 years of usage under normal operating conditions as opposed to the normal 300 – 500 cycle life of deep cycle lead acid batteries.
Fast Charging: Use of Lithium chemistry allows for high current charging, minimizing down time and allowing for maximum use of available solar power.
Safety is a core value of the Jarrett team. Our Lead-to-Lithium conversions are equipped with high-end Battery Management Systems (BMS) that are the ‘brain’ of the converted battery pack.
Comprehensive Protection: The BMS automatically protects the battery from over-charge, over-discharge, over-current and short-circuit.
Temperature Monitoring – Discharge – Operating Temperature Range for monitoring battery discharge temperature. The operating temperature range for this feature is from -20°C to 60°C.
Smart Communication: Integrated RS485/CAN and optional Bluetooth/Wi-Fi modules allow users to monitor battery health in real-time via smartphone or PC.
Jarrett recognizes that the need for energy is constantly evolving. Our lead-acid replacement batteries are designed to scale up massively.
Our battery systems are scalable to any size and can run up to 15 units in parallel. This means that you can start with a single 5kWh unit and as your energy storage needs increase, add more units up to a massive 230kWh energy bank.
Inverter Compatibility: All of our systems come pre-programmed to communicate with all of the major global inverter brands. It makes for a simple ‘plug-and-play’ installation for any installer.
Simplified Installation: The product comes with standard terminals. It has a compact design (e.g. 545460200mm) so it can fit in existing battery racks or be wall mounted.
