PowerPak 2.5 X 2 Pro 2500mAh 7.4v Li-Ion Powerbox Battery 2525
New energy for the best of models - with the new PowerPak range! PowerBox Systems presents the next generation of the PowerBox Battery series.
The PowerPak series boasts a whole array of new and innovative features. Various versions of the PowerPak are available: PRO and ECO, and each as an 8.4 V pack for receiver power supplies, and a 12.6 V pack for turbine batteries.
The balancer circuit ensures that individual cells are not overcharged, as even Li-Ion cells are extremely vulnerable to this state. Unbalanced cells can drift apart in condition, leading to loss of capacity, and accurate balancing also effectively eliminates this danger.
Like all PowerBox Battery types, the PRO version features a fully integrated charge circuit and balancer unit. To charge these packs all you need is to connect the integral charge socket to a 110 V / 220 V mains PSU or a 12 V car adapter. Battery voltage, battery current and charge time are constantly monitored by the integral electronics, completely eliminating the possibility of operating errors.
The internal voltage monitor circuit indicates the battery's state of charge using the integral LED, or an external plug-in LED.
The micro-controller built into the PowerPak PRO implements one entirely new feature: the battery is automatically discharged to 3.8 V per cell if a period of storage lasts longer than six days. The reduced voltage is a safety feature, and also avoids premature damage to the cells, thereby enormously extending their effective life.
Every version of the PowerPak is fitted inside a robust case, and is supplied complete with a standardised mounting frame. This enables the modeller to swap batteries quickly, or simply shift the pack from one model to another.
For even greater flexibility, PowerPaks do not feature a fixed connecting lead. Instead each pack is supplied with a lead to suit JR / Futaba or MPX 'green' connectors.
All our battery packs are subject to a certified production process, including legally prescribed certification in accordance with UN38.3. It is therefore possible to ship these items.
If after a few years the cells in a PowerPak should become exhausted, we offer - as usual - an economic cell exchange which includes a check of the electronics.
