Optimate 20W Solar Duo Pulse Charger, Tester & Maintainer Travel Kit

The OptiMate 20W Solar Duo Pulse Charger, Tester & Maintainer Travel Kit helps you charge, test, and maintain 12V lead-acid and lithium LFP batteries using solar power. You use its smart controller, pulse charging system, and six-step programme to manage battery recovery, maintenance, and overnight monitoring when solar input is not available.Discover the key features of this kit:20W Polycrystalline Solar Panel: This weatherproof polycrystalline panel produces up to 20W at 12V with a 1.67A maximum average charge current delivered through a 200cm SAE-equipped output cable, allowing sunlight to be converted into usable power through high-intensity cells and an aluminium frame with integrated mounting brackets so your battery receives steady daytime charging for regular upkeep.TM522-D2 Smart Charger-Controller: This controller manages a six-stage programme featuring test, save, charge, optimise, maintain, and monitor functions, using 15 22V input, 3 5A pulse current, and a low-volt start capability at 4V to recover deeply discharged batteries while preventing overcharge through full electronic protection, giving you clear progress updates through a 5-LED display and supporting safe long-term maintenance.Pulse Charge Conversion Technology: This feature converts low or inconsistent solar energy into a high-efficiency pulse charge by regulating incoming voltage and delivering short current bursts that improve charging performance, helping you maintain usable battery levels in weaker sunlight so the battery reaches a workable state sooner.Automatic Day/Night Switching: The controller switches from charge and maintenance mode during daylight to a monitoring mode every three seconds at night, using internal sensing to detect when solar power is present or absent so you receive continuous information on battery condition without needing to adjust settings.IP54 Weatherproof Rating: The panel and controller housings meet IP54 resistance levels for dust and water spray, using sealed casings and protected connectors to support outdoor installation in changing weather so your charging setup remains reliable throughout the year.Included Connection and Mounting Options: The weatherproof O-1 battery lead, O-4 clamp lead, four suction mounts for window placement, and nylon travel case offer flexible installation and storage by allowing fixed mounting on roofs or walls, temporary mounting on smooth surfaces, or quick connection when travelling so you can place the panel where sunlight is strongest.Multi-Chemistry Battery Support: Compatibility with STD, AGM, GEL, and lithium LFP batteries from 5 80Ah allows the controller logic and charge stages to adapt output to each battery type, helping you maintain correct charging behaviour so each battery receives appropriate care for everyday reliability.Safety and Electronic Protection System: The built-in spark suppression, automatic shut-down for short circuits or disconnection, and full overcharge protection use internal safeguards to control current flow and protect vehicle electronics so you can leave the system connected without needing to supervise operation.This kit helps you keep your vehicle ready to start by supporting regular charging and reliable monitoring when a mains supply is unavailable. The combination of pulse conversion, low-volt recovery, long-term maintenance, and weatherproof construction makes it a practical addition to your vehicle setup when you want dependable battery care in storage areas, outdoor parking spots, or during travel. It is a smart choice to keep in your gear if you want a portable solar charger that maintains battery condition while fitting neatly into a compact storage space.
