trition vs ice vs t15/26

which one is better?
i kinda like the ice charger cuz of its graph feature. from the graph u can know the condition of ur batt packs. whether it is good or can throw away liao.

The graph is pretty useless to me... :P
I think if u pull out a search, u should be able to find my previous review on it.

the discharge graph is good. u will know when ur batt is going to die
n wad batt packs are good n wad sux

generally, once your batt hits below 1.2v per cell for NiMH or the nominal voltage for lipos, voltage drop will be extremely non-linear, and it also depends on your load current... if current draw is high, voltage fall-off will be much faster.

If a batt is going to go up the lorry, first signs is that it won't charge to the full rated capacity after a full discharge. For NiMH cells, u do a full charge to discharge cycle, check the reading of the amps being put in the cells. Then check the amps being discharged. If a cell/pack is dying, usually you can do a full discharge of the rated capacity because voltage cut off will occur earlier.

Any mode of graphical readings is just a intrepration of time or current draw vs voltage drop. Graph or no graph, still can determine if your cells are dying or not..

Typo:

If a cell/pack is dying, usually you CAN'T do a full discharge of the rated capacity because voltage cut off will occur earlier.

Beg to differ, ....usually the 1st thing I do after setting a battery to charge is to look at the curves in the graphing screen, dying cells ramp up differently from fresh cells.
....the graphing feature is even more critical during the discharge cycle as it tells me how long the pack can hold a certain voltage i.e: how the pack will perform in the air.

For your purpose, discharge graph is useless unless the discharger can simulate the actual or near actual discharge rate. - Assuming - your aircraft draws 40amps and discharger can only discharge at 5amps, in this instance, the graph can't simulate the actual current draw. The batt will normally hold the voltage better in low amp draw than at high amp draw.

Personally, I use graph to monitor batt pack condition. By comparing the stored graph profile against the latest. If the latest is better than the stored copy, the stored copy will be replaced with the latest. Battery tend to performed better after a few cycle. Usually, if a pack is going, the charging characteristic also change.

It really depends on your needs. Can those mentioned charger meet all your requirements? Do you like individual charger charge characteristics. Some charger charge upto 95% capacity, some 100%. Some charger charge the batt hotter than others.

I understand what you are trying to say, but when you say the motor draws 40A, is that contant or momentary current ? ....from my experence, I find that when you push the throttle to full (ie: on take off) the current draw will spike to 40A for a split second then drop back to about 2A - 10A (Depending of motor/prop selection)

If you subject the battery pack to 40A constant discharge (Assuming a 3C1P 1000 Mah pack) ....thats a 40C abuse ! I dun think the battery will last that long ! ....Yes, I know you could setup your packs to 3C2P or 3C3P to better handle the current your motor draws but thats beside the point.

I've discharged/Cycled packs at 4A constant current and they were hot at the end of the discharge (Cutoff at 3V/cell) ....can't imagine if they were to be discharged at 40A constant current.
