The Trystar ChargePak Portable Battery Testing System (BTS) is a fully integrated solution designed to simplify, accelerate, and document NERC PRC-005 and IEEE 450-compliant substation battery testing. Combining a portable battery charger, load bank, a bank of 125Vdc-50AH batteries and an integrated cabling system, ChargePak eliminates manual setup and battery movement. Its plug-and-play design minimizes human error, while robust VRLA lead-acid construction ensures durability in harsh conditions. Built for reliability, accuracy, and safety, ChargePak streamlines maintenance, reduces downtime, and ensures full regulatory compliance.
