Can I use more than one LED on the Ultra Guard 430?
Can I use the Ultra Guard 430 with a BEC?
How far can I discharge my OPTIPOWER pack?
My Ultra Guard get quite hot is this usual?
There are parts that get hot during charging. The temp with around 65°c is nothing to worry about. The board has an over-temp protection of 80°c. However it also depends a little bit on mounting position and environment temps. The board is absolutely fine.
My Ultra Guard LiPo is only 90% charged is this right?
The LED appears to be on all the time?
What C Rating are OPTIPOWER packs?
We also supply a high C rated pack called the ULTRA packs these are 50C true and give superior voltage hold.
What voltage will the ULTRA Guard work over?
The minimum voltage it will set at is 4.8V and set to 4.3V the maximum is 8.7V and set to 8.2V
Will the Ultra Guard work with a LiFe pack?
Will the Ultra Guard work with a LiPo direct on the system no BEC or regulator?
Yes it will. One thing to bare in mind is that if your RX LiPo is older or of poor quality the voltage migh drop very soon on load to a lower set point than the no load voltage. This might switch on the UG430, this would not damage anything but this is the reason.
Will the Ultra Guard work with the YGE ESC?
If the BEC fails and the Ultra guard takes over, isn't there the potential issue of it supplying voltage ``backwards`` to the ESC through the RX/FBL unit via the throttle cable since the connector bus on the FBL unit is common and can be powered from any port? I'd really hate to fry a $200+ Castle 120HV ESC. The FBL unit in question is the Spektrum AR7200BX.
Under normal circumstances the UG430 sets below the BEC voltage by 0.5V so no damage can be done as its a lower voltage than the BEC output. If the BEC fails you loss everything anyway so you will crash the UG430 will allow the model to be auto rotated down safely with no damage.
