Any way around Low Voltage cutoff in Schulze controllers?

[BJMFH1.01]

Is there any way around the low voltage cutoff in most Schulze controllers? I checked in the manual and couldn't find anything (aside from the 9.12 or something like that).

The problem is, I have alot of older battery packs that don't hold their voltage too well. They perform fine as long as I grab them as soon as they're done charging. If let them sit for more than an hour, the low voltage cutoff kicks in. It's not too bad but I can't full throttle my truck from a standstill or low speeds. I have gradually get on the throttle.

Whenever I use these batteries with my other ESCs, the RC just gets slower until the batteries are fully discharged. Do I just need new batteries or is there a way around this annoyance?

The thing that really kills me is that the voltage cutoff is set way too high for nicads and nimhs but way too low for lipos. What a joke right?

The low voltage cut off is probably there because the U-Force requires a certain voltage to operate, and can't when the voltage is too low. If this isn't the problem, then the cutoff should be adjustable.

When i e-mailed schulze this question they replied that the controller itselt needs a minimum of 5V. I was wanting to use the U-force 75 in a 1/12th on 4 cells. What controller are you using? I believe all the schulze future and u-force series controllers have an adjustable cutoff but the minimum setting is 5.4V I think.

Get new batteries!!! www.battlepacks.com has some of the cheapest 3300's I have seen at under $20.

I know where you are coming from though I have a few older packs that I cant use because of this. Try cycling them a couple of times then charge to full. And make sure you aren't dead shorting the older packs, or discharging very low with bulbs. This really hurt my older packs.

I have the 40.160 and as far as I can tell, there isn't a way to adjust the low voltage cutoff. I can understand the need for one in an aircraft, but not a car. Schulze should have left it out when the controller is set in car mode.

I would get lipos but the voltage cutoff in my controller is too low for them. I've heard about some voltage indicator that lights up when the batteries get low. But that wouldn't work either because I'm very rough on all my equipment and there isn't a safe place to mount it where it would be visible.

With my controller it isn't a specific voltage number like 5.4 (heck my controller needs at least 10 cells to even operate). Whenever the batteries drop below around 59% of their original plug in voltage, the low voltage cutoff kicks in.

I've already tried cycling my older packs a few times to no avail. I mean granted, these packs probably have well over 200 charges on them. Oh well, I guess I just have to get new packs.
