The Turnigy Heli-UBEC is a great option for models requiring up to 5A continuous current and 5V/6V output. The output voltage is easily selectable by switch. The input side features a JST plug pre-installed, while the output side uses a JR style plug for use with any receiver.
The Heli-UBEC is compact in size and lightweight, making it ideal for mounting conveniently on your helicopter frame without taking up much space.
Features: • Compact in size • 5V/6V selectable output • 5A continuous output current (7.5A burst) • 6~16V input range allowing for use with 2~4S lipoly battery packs
Will this UBEC voltage regulator work in the Thunder and Monsoon sailboats recently purchased from H.K? I could find no data in the literature on the site nor the assembly guides that came with these vessels so I ordered two 2S 40C 3600mAh Turnigy Lipo batteries, also from H.K. I am using H.K. Orange R620 DSM2/DSMX 6Ch Rx units. I'm interested because when I connected one of the batteries it melted the wires to the sailwinch servo destroying that unit at least. I have spent the past several days in an effort to discharge the batteries voltage to 6V using an iMAX B6AC (H.K. of course) a level I now believe to be acceptable for the servos. The UBEC seems like a better, more reliable means of controlling voltage than tedious discharge and, with an input range of 6V ~ 16V, it appears that it ought to handle the 7.2V easily enough. Thank you for guidance and advice in this regard.
Thanks, Stevos. That's a helpful tip on Lipos, too, but then again, Nickel batteries must be fully discharged before recharging or there is some memory loss equivalent to the amount not discharged, I'm told. As I've also heard, the same applies to the upper end, if for some reason the battery isn't fully recharged there will also be a memory loss equivalent to the amount undercharged so that future charges will find the level of undercharge to be the new maximum. Is this correct information? Thanks again for your help, Stevos.
CA, Lipo's are a completely different chemistry to NiCad's. they don't have a memory like them.
You must never discharge a LiPo below 3 volts / cell,(3.3 recommended) and never charge them over 4.2 volts / cell otherwise you will risk burning your house down.
It's designed that way to let you know that you have a battery plugged into it. This makes sure that you don't forget about it and damage the battery permanently. Beside you only see it when you remove your cover so it shouldn't bother you that much.
Yes ,I was wondering about the red led too. I am also connecting the battery directly to the regulator* I wonder if I could connect the regulator AFTER my typical three lead on/off switch ,so that I can use the switch to switch off the red light ??
