Default 20 Amp Discharge

Hey guys, i have 2 eqaulisation trays, that cut of at .9veach cell, witht the light bulb

What i wanted to know was i want to built or get a 20amp discharger, woth a .9 cut off, but still would let my equalize trays to work.\


Any ideas welcome, its is for feral 3600s by the way

If you still want to equalise the cells you'd be better off cutting your packs voltage off higher, like 6 volts then equalize instead of 5.4.

You'll be first to have one if you pull this off Might be a good business idea.

u can build the bulb discharger ...with a relay.

by using resistor it can cut off at ur required volts 6. or 5.4

im not too sure which as a friend help build it for me ..works really well
always cuts off at bout 5.6 volts ..

if you want to build a 20amp discharge load, you can do it with resistors. you will need 27 1ohm resistors. 10watt ceramics will be best but i have made one using 5 watt ceramics with heatsinking (cheaper). you need to make a series of 3 resistors.make 9 of these. run the 9 resistor series in parralell. this will give you a 20 amp lad for 6 cells.connect a voltmeter to the load to manually detect voltage cut off, or you could connect a deans black box in between the pack and the load to get auto cut off.
