SMC LIPO BATTERY THREAD
#2836
Aggressive would be charging at 4-6c which for a 5000 mah pack would be 20-30 amps, Danny does alot of testing with all his packs before he decides to put the SMC name on them, he doesn't just buy packs and slap stickers on like some companies do. Danny's testing shows his packs can handle a 6c charge, of course that will drastically reduce the cycle life of the pack. Danny recomends charging no lower than 2c.

I think Danny said no less than 1c, 2c is the best balance of speed and quality of charge and 3c is about as high as you should go. 3c ceiling not for safety but for the quality of the charge.

^^^^^^Post #7 of his thread by the man himself^^^^^^^^^
This is the response when asked about charge rates for a shorty 4600 70c.
He posted this same info numerous times throughout the thread when asked about charge rates for all the packs he sells up until the time he was not allowed to post here anymore.

Hello. Just ordered one last night. "Factory Spec 7.4V Shorty 4300mAh 50C Inboard "
Can someone please confirm the "C" charge rating that can be used? This is my first time to use higher than 1c, so a bit nervous and wants to 2x check. Sorry if this has asked. Thanks

2C, or 8.6A is fine.

I don't doubt that you guys are charging packs as 10+ amps but I've never seen a pro charge at more than 1c and we have guys at the track from Kyosho at least a couple of times a week and AE every so often and not 1 of them ever charges at more than 1c. I look. Is it possible there's a new normal and nobody has caught on yet? Sounds like I need to move up to a Power Lab 6. Still my 7 amps, that you guys are mocking, is the most anybody that I know and race with charges at. I just ordered 5 6500 SMC packs. I think that my chargers can charge @ 10amps. I'll try it out when the new packs arrive. It'll definitely save some time.

Running 1c or lower won't harm the pack, but has no benefit. Charging super low (like 0.1c) ca damage the pack as most chargers aren't precise enough to do the job well as the low current settings. This goes for most brand packs.

I've ordered twice and my orders have shipped the next business day both times. And I've been really happy with my purchases! And they ship USPS Priority so you get them quick once they are shipped out.
