I know that now. Lol. I thought it was just odd that only 1 cell swelled out of 4. It was the top cell in both packs.

Thanks,
Joe

I need some advice guys on new lipos for 17.5/10.5 tourer with a spx and lrp 10.5/17.5 I see nothing but good reports on these and we have a local retailer in australia i can get them from reasonably cheap. Ive had my intellect 25c and 35c 3800 packs go soft recently and im not sure if its from over use from being charged heaps while racing 2 classes(tourer/mini) or whether ive left them without enough charge or too much charge, I don't know. I want to ask, Is this charging in a day just bad for lipos or will quality lipos like these SMC ones stand up to the abuse of being balanced charged in the morning and re peaked after each of 3 heats and 3 finals in the one day? Or should i get 2 packs to run and let them rest a bit before being re peaked? How many Lipo packs would someone normally use on a club day with 3 heats and 3 finals.

Much appreciated, Benzaah

Benzaah- I run 17.5 with these packs. I am currently running two of these. It takes about 48mins to ballance charge these after a run with 17.5. I reckon you could get away with one (depending how many races are between your races) but i would recommend two packs, in my opinion i reckon its good to let the pack rest a bit before i put it back on charge. You won't be dissapointed with these packs, gained so much more compared to my IP 25C, not saying the IP's are bad packs but the bigger SMC's just have more power!

Looks like ill have to get myself a battery brace for my xray then as i frickin hate taping batteries all day. We usually only run 4 classes with 1 heat of each in around 40mins a round. Being winter here at the moment as well as racing on an outdoor asphalt track in the hills the numbers drop. I usually run mini and stock so its race, marshal, race, marshal with not a lot of time to do bugger all in between. If we get a full field of stock i can usually get away with only marshaling after mini.

Also, Do you balance charge every time. I would only normally do that for the first charge of the day and then just peak it back up with a normal charge for the rest of the time. It does usually take around an hour and a half to balance when i do it that way but im not sure how much my packs are degraded.

Cheers Benzaah

I use a velcro tie in my Yokomo... That way I don't have to worry about constantly re-taping

Yes i balance charge every time i charge the packs. I only race stock and we have about 1hr 20min between races lol over 10 races per round most club meets, so i have plenty of time. It only takes about 50mins to balance charge my packs. Could be different for other packs not sure.

Default Blue 4700 40c pack

Hi

Does anyone know if the new blue 4700 40c packs fit directly in to an Xray 2008, ie without having to modifuy the car or the pack and also without having to use the lipos riser plates.

Are the packs 25 mm with or without the bumps?

Thanks

mark
