Lipo4, Lithium, Iron, Phosphate battery systems. The most advanced, efficient and reliable energy storage system ever made. Virtually no maintenance or fire hazard and designed for thousands of discharge cycles.

7th generation of API Lipo4 energy storage systems include, all cells house in a heavy duty steel container. BMS, main circuit breakers for charge and discharge plus on/off switch house in a separate, isolated steel compartment with wiring access holes to accommodate metallic flexible conduit. Systems have one compartment for battery cells another isolated compartment for access wiring. We now have 2 separate CAN communication ports to control AC charging, on/off and current. We also have 7 separate 12 vdc triggers to control generator on/off, solar, wind hydro on/off or any other type of load or charging potential. Our remote monitoring system allows for easy verification of all cells, system status, voltage, temperature, charging, discharging and programming. Please call or email for more specs and information or stop by our stores any time to inspect these truly revolutionary energy storage systems.

7th generation Lipo4 communication wires. 2 CAN circuits to control two separate AC chargers (charge rate and on/off voltage). Plus 7 12 vdc adjustable triggers to control gen on/off, battery charging on/off, solar, hydro, wind on/off or any other type of load and charging source that can be controlled by a 12 vdc relay coil. We always use solid state relays for solar charging controlling. Most systems PV systems are wired to 600 vdc to these relays, then to a 600 vdc MPPT controller. The controller is only used for the MPPT circuit, the solid state relay turns the PV power on/off based on BMS settings.

API Flex Energy System

13 kWh Energy storage: Lipo4 battery system 252 AH, 16 cells, 51.2 vdc nominal (24 vdc systems are 2 cells in parallel and 8 in series, 25.6 vdc nominal), incased in heavy duty fire resistant, steel container. Internal BMS power supply. Easily accessible system on/off switch. All necessary safety equipment, complete monitoring and metering. Conforms with UL 1642 &UL 2054

AC Inverter Power:
Magnum 4400 watt, 48 vdc, 120/240 vac or 120 vac only, expandable up to 17.6 kW. Our API FLEX system is versatile and can accommodate any nominal 48 vdc inverter system, Schneider, Outback, Magnum, Exeltech, Samlex, etc.

AC charging system:
systems are the only Lipo4 systems with their own, separate charging system (solid state, 50 amp and 100 amp continuous, 240 vac input, CAN protocol. Charging rate can be adjusted via the BMS remote) specifically designed for Lipo4 charging. This allows simultaneous, system charging and discharging. You can run off this system 100% of the time. Resulting in a much "smoother", more reliable and versatile power system, because we do not switch between different power sources. External Power sources can be grid, generator or any other AC power supply.

500 VDC Lipo4 Battery Based Systems:

These systems have been totally designed around the battery bank. 400-500 vdc (this voltage allows us to optimize battery/inverter/charging performance and in many instances fully recharge the battery bank in minutes not hours or days). 5 kW Pure sine wave inverter, AC charging circuit is specifically designed for these batteries. PV, MPPT charge controllers are also designed for Lithium Ion battery banks. These systems can be scaled to 1 MW. Spec sheet can be found here.
