User questions & answers

Question:	what is lowest voltage relay can be adjusted to that will close relay to charge battery
Answer:	The drawer/keyboard tray supports cross under the top and leave only 18" from the shelf to the bottom of the support. I suppose you COULD shave 1/2" to 3/4" off the support on one side without affecting the hardware. That is the only obstruction that I can see. But that would also void any warranty I'm sure. We love our desk and get many compliments on it. It really is a solid attractive piece of furniture.
Question:	Can the input be a regulated DC source
Answer:	Hello. You will need 35 inches from the corner to the end if the desk on each side. It is 33 inches deep from the corner to the middle front of desk. Hope this helps.
Question:	Can I set this to disconnect on discharge at 6v on Nimh battery
Answer:	I haven't had an issue with it sliding or moving. I first used it on a glass top desk and it stayed nicely in place. Now I'm using it on a wooden desk and also have not had to adjust it at all.
Question:	Diagram is confusing...ac input on k1 and k0? can it be dc input
Answer:	Yes you can cut the desk mat. It won't roll or fray. Just make sure you cut it properly.

User questions & answers

Question:	Will this work with agm battery
Answer:	Not an expert on measuring but it is slightly over a 1/2 inch. I believe it 5/8 of an inch. Not very thick at all. It’s a very nice deck with exception the holes in the desk did not align with the holes in the frame. It’s basically useless to me until I find someone who can drill new holes in the frame. Good luck 👍🏽

User questions & answers

Question:	I have a 130amp alternator. will the 60amp renogy dcdc charger be too large and damage the alternator? how about at idle for up to 1 hour
Answer:	I had a 40A on my 160 amp alternator and noticed a straining noise after a few months that has since gone away after removal of the Renogy. Alt. runs at about 50% when idle, so it would theoretically cover it, but you're not leaving much left for the vehicle systems. I would step down to a 40 or even a 20.
Question:	At 40A, I'll have to run the engine for 2.5 hours to charge a 100 amp hour battery (from completely drained). Correct
Answer:	In principle yes, however, it will probably take twice that long for a "full charge." From the discharged state it will charge at 40 amps but it will reduce the charge rate for best charging and battery life. You don't want to run from full to empty and back every day. I have your configuration (100 amp hour battery and 40 amp charger). I drive 40 miles every day and it is enough to charge the battery for my CPAP and other medical devices for the night.
Question:	What size alternator do you need for this to work
Answer:	I use the 40A version on my Chevy Express with 145 amp alternator. It works fine so long as you're not over-taxing your alternator by trying to heavily charge your engin battery or run full accessories in low speed or idle conditions. For that reason I installed an "ON/OFF" switch in line so I can leave it off at the start of driving to give the alternator time to top out my engine battery. Then, I can switch it on and charge my rv lithium batteries at 40 amps. No problems doing it this way.
Question:	Where does the D+ wire get mounted to? I can interpret the instructions in three different ways, so I am curious what you all have done
Answer:	The D+ wire is a + voltage sensor to turn on the DC to DC Charger only when engine is running. The D+ wire gets hooked up to the fuse panel's ACCESSORY fuse slot, where Accessories only gets +12VDC when engine is running. Use an ATC Fuse Tap with crimp type "blue" butt connector connected to the D+ wire, insert 2 of the same Amp fuses into the 2 fuse tap slots required for your vehicle's Accessories. Although the D+ wire draws no current, it detects when a + voltage is present, the fuses protects vehicle's Accessories. It works.
