Jericsm: Most racers cut off the lightspeed connectors and hardwire for that reason.

rcethilon - the pro-trak discharges at 20A - however on recent software versions you can fiddle the numbers to give a 30A-style readout - but that's not the same as the real thing.

As for heat, plenty of warm air gets blown off the heatsink, but I would not say it's ever likely to overheat (unless you put it in a very enclosed space).

Keyence - I pretty much follow proudwinners advice there, except if I know that I'm not going to be using the cells for some time I'll put a part charge in them.

I'm actually falling out of love with the whole part charge thing - I found that my old and tired Sanyo 3000's would not hold any voltage whatsoever over time, so if i took a pack that I'd part charged a day or so before, then discharged it, it would go down to 5.4v very quickly - giving a false impression of discharge, because there was still 1000mah+ in there.

This caused a problem once with my pro-trak, which has a capacity lockout feature to stop false peaks - I ended up overcharging my cells with a delta of something stupid like 0.50v (rather than 0.07), because the 1500ma lockout was going on top of the 2000+ in an fully charged, but low voltage, pack. the cells survived, but I think i was lucky.

Moral of the story - when charging/discharging cells that have been rested for a while, keep an eye on them.

I'm really thinking about storing my 3000HV's & SMH's pax fully charged-FOR REAL! No joke. NiMH's have a differant chemistry than the NiCads. With NiCads you actually boost the voltage by traying them time after time- I know, I own 4 packs of Lightspeed 2400's and they're awesome after a good charge and repeak. I'll never forget the way my Panasonic 3000's(1st editions) lost voltage every time I charged them, and I didn't tray them. I bet you that if I do store them fully charged inbetween races they will actually last longer.

Some people call them lightspeed, some people call them power pole. They are the red and black conectors that are on T30's and T35's.

I just took my HV's of my tray where I forgot them for two weeks ;-)

The showed much better numbers than before. Run time and voltage came up and IR went down.
Mine will stay on trays now just like my 1 year old SMH's.

Ovalman19's right, Lightspeed connectors are the same as the Sermos/Duratrax/Anderson Power Poles. Anderson makes them, & several companies buy them in bulk & market them under their own name.....

well, what i did was change it to deans.... and i also changed the wires from the crappy plastic covered ones to silicon covered ones.... 14GA, i think.... wrong move.... i think the wire resistance was part of the circuit.... it now terminates the charge with a 'HOOK UP BATTERY' message.... when i put the original wires back in, it was ok again....

Motorsports, you should end up with better numbers than that, when I last cycled mine they were 1.14 @ 30 amps

Hi

I'm just about to invest in some 3000HV's, I was looking at SMC's but can't find any in the country so I think I'm going to go with some Fantom Team cells. Anyone got any views on them, or anyone know where I can get SMC's in Australia. The land where the Chrome stock is the latest stock motor!!

Also, I've got an Apex Sigma+ charger, this discharges at 10 Amps, charges at up to 6.5 amps. I don't know what the cut-off voltage is, the manual talks about "cut-off at 45 Deg C without the need for a temperature probe"???? Would this be capable of getting good perormance from the cells?

Cheers

Man, I once doubted someone(on the Yokomo thread, I believe) when they talked about how big a difference it makes not to have the extra layer of strink wrap on cells. BOY WAS I WRONG!

I couldn't get my Integy 3000HV cells(which came with extra shrink wrap already on them) to fit into any of my cars without modifying the battery holders. Finally when I just got my Mission, I couldn't get them to fit in there at all, period. I didn't want to modify my Mission so I decided to try removing the shrink wrap to see if it would help.

Man did it ever. After removing the wrap on all the cells, the pack dropped right into my Mission with ease.

Man, I never would have 'thunk' that the wrap made the packs that much bigger. Guess you learn something new everyday.

Default SMC 3000hv's rock

If your looking to get new batteries try the SMC 3000hv. These cells are the best i have ever run. Great power in mod and stock. TTYAL
