so theres no indication that the cell hits below 0.7?

How do you know when it has reached .5 volts, and how long does it take to reach .5 volts from .9 volts? Why would the Leds go off a .7? The pack isnt equalized at .7 since different cells will hit it at different times, and it doesnt hold the voltage at .7 but continues discharging. Are you supposed to have a separate tray for each pack or can it bring a pack down to .5 volts in a decent amount of time?

As Cuffs pointed out, this isn't the case with the Tekin product. Which reminds me, will there be a Cuffs Signature edition?

you must align the battery so that the pos end is in the bottom right and the neg end is on the bottom left. otherwise you will smoke the pack and the smart tray. it says so in the instructions.

Because its Tekin!!!

Non-polarized easy use and it does what your batteries need.. a gentle discharge and balance. The leds are actaully per cell and indicate connection and charge status... pull a tab on most trays and see how many lights go out. Also looks pretty cool.

hey guys

8 cells is a perfect idea for 12th scalers!

is 0.5 volts safe for ib3600 the new generation ?

Okay, loaded/cheeky question:

What advantages does this Tekin Battery Doctor have over, say, the Teamwave Lightning?

The Lightning says:
Quote:
When cut-off voltage (User select from 0.7V to 1.0V in 0.01V increment) is reached, the system will automatically lower the discharge current so as to maintain the cell voltage at the desired cut-off level and let the discharge process to continue. Compared with traditional discharge tray, the discharge process is considered finished and the pack will be cut off at this point. In fact, plenty of charges are still stored in each cell. A pack cannot be effectively equalized if there are still a lot of charges inside each cell.
In other words, it keeps it at that VOLTAGE, but still discharges CURRENT. Does the Battery Doctor do this, too?

Give me the selling points of the Battery Doctor over the Lightning... my spending finger is about to pull the trigger.

(Apologies for the cheeky questions).

Lets try an analogy. Its like an outlet on a lake. When the lake is full (high voltage) the water(amps) is rushing out. As the depth (voltage) decreases there is less water flowing out. Eventually the depth is low enough that no water flows. If water is added to the lake a little flows out... the lake is held at a steady level.

If you close the outlet the lake will rise. The Tekin tray leaves the outlet open as do most. I believe the orange tray does disconnect the load and allow the battery voltage to rise. Most just use a diode to determine the voltage cutoff. Due to our non polarity design, the 4 ways you can put in a battery pack and the leds actually being per cell, ours is a little more complicated. If you have ever discharged 5 cells out of 6 and then charged you know this is important.

Basic math is I = V/R... unless you have a very fancy adjusting load than as the voltage approaches the cutoff the current draw goes down because the resistance is constant.

We actually have a 2 step cutoff. The leds fade out around .8volts and the current draw is reduced to very small. During the slow discharge all the cells catch up and discharge together down to .5volts and hold till removed. We have left them for weeks with no drop in voltage below .5volts

each tray is 8 slots. 8+8=16. 3 6 cell packs are 18. So unless you are running 5 cell packs, no.

The LCM of 6 and 8 is 24. So you could get 3 trays and discharge 4 packs at once.

Joking asside, you need to have three cells linked together to create the circuit for discharging.
