brushless and A123 questions

All,
With the proper length of wire the charge rates are oK. Mine started at about 8 AMPs. There is a on going thred over at RCgroups about this. The tester is up over 100 charges and is yet to see any change in cell performance.

The Problem with using my NMHI charger is that they will never see the end of charge. thus if you do not watch closely the voltage will continue to climb way above 12 volts until the cell pops. Then it is toast. The benifit with the Zip charger is that no mater how long you leave it connected it will never climb above the votage of the deep cycle battery (13 volts or so), Also as it appoaches full charge the rate of charge slows down Mucho. Thus as long as you don't fall asleep it is unlikely that the voltage will get much above spec, and even if it does, it will only be slightly above spec and all reports I have read so far state, no damage done. Most say it would be bad to leave it for extended time but I have not read about any tests of that. keep in mind that the charge rate was down to 3 amps by the time the cell what 95% charged. It probably would have been below 2 before the cells were getting to 4 volts per.

All that said, Yes there is room for improvement. The charger works great, I would only ask for one thing. When the charge voltage reaches 11.5 volts to have it auto terminate.
