Designed for F5J competition gliders.

This is a very small power switch designed for F5J competition gliders. Small, very strong and super reliable, due to it's redundant functionality. The switch automatically chooses the battery with the highest voltage. The output power from the Zepsus will not be interrupted even in the event that one battery short circuits. When both batteries are the same voltage the Zepsus draws from both, simultaneously.

The Dual Battery provide redundant functionality, which provides security. The switch simply selects the battery or BEC with the highest voltage. If the voltage is the same, the power is drawn from both batteries or BEC’s. If one battery or BEC is removed or short-circuit, it will not affect the other battery or the output voltage. The idea is to use 1S Lipo/4S NiMH or 2S RX lipo depending on whether RX lipo should be the main RX battery (2S) or backup battery (1S Lipo/4S NiMH).

The switch has an ultra low power consumption rate in the off-state. The consumption is so low that the switch can be connected to a 1000mAh battery for several years without discharging it. The switch has a built-in failsafe function. It remembers its failsafe state for at least 10 sec when disconnected from the supply battery. It will protect the glider against power glitches caused by intermittent battery connections or other momentary electrical disruptions.

Production testing
All switches have been tested at 20A for 30 sec before delivery. Standby consumption is adjusted and a visual inspection is made.

As advertised

This is my second one and made second purchase as first one works excellently


Zepsus dual battery switch

Very poor directions on installing unit with two batteries


Very Nice for Dual Battery Setup

Works as intended, as far as I can tell in a large scalie with dual batteries. Be sure to check the connectors, though. I've used lots of Zepsus switches over the years and this was a first, but there was a bad servo connector on the receiver side of the device. Crimp connector had not been pushed in all the way and unplugged the positive wire when I tried to plug it in. Could have been pretty **** but it was an easy fix.


Solid Service

Even with the Holidays I got my order quickly. Much appreciated.


Simple, small reliable

I’ve been using the Zepsus Dual switch for years. It provides a backup battery in case of the unlikely event of a BEC or ESC failure. Never had the BEC or ESC failure, but the switch does work as advertised. Easy magnetic on/off. Simple foolproof reliable way to have a backup power system for my sailplanes
