We have worked with Powerbox from the beginning, sold more products than any other UK dealer. If you want to do it right contact M&R and speak to Dave
Need to use extra servos on a big or fast model? Running extra long servo leads? Need the security of two batteries? Want two batteries and a fail-safe switch?
Powerbox units feature powerful servo amplifiers and screening from interference. Dual circuits throughout- no corner cutting. The Switch only units allow Li-Po cells (built in regulators) to be used for long flying sessions-more flights/mAh than Ni cells.
Powerbox units, Sensor Switch, Gemini Switch and all PB units give 5.9v which is perfect for all servos including JR Servos. Only unregulated 5N cell packs should not be used on JR servos as fully charged these are over 7.0v.
Powerbox also have their own user forum
