So I just killed my lipo pack...what to do now? - RC-Monster Forums

I've liked the idea of the A123s, its just the form factor, low mah and charging irregularities have kept me from them. My pref is changing now tho.
A 30min bulletproof charge would be awesome tho. Makes getting two packs to make up the mah seem doable.

For clarity, the "5S" pack is not one pack, its a 2s and 3S pack w/ Y. It has hyperion/apache taps. I'm just not sure if wires can be inserted into the tap molex, or you have to buy them purpose-built. photobucket is blocked here, its not your link. haha least RCM is not blocked, (neither is youtube for that matter... ? wtf IT guys. )

Don't forget that A123's have a 100% usable mah rating, unlike lipo, you drain them right out, which is very abrupt when it happens. So the difference isn't so much then.

The M1's yes are bulkier than lipo, but they are very light for their size, they need to shrink them smaller is all.

Hmmm.. that is a a good point. :) You have seen they have the new 32 series cells listed on the website? Have "ultra" cells as well for better connections. Haven't seen any detailed specs yet, but thing are looking very interesting.

I did the exact same thing. The esc switch only shuts off the esc, but the servo still gets powers. I ruined 2 Maxamps 6000's, so I decided to put the nitro motor in the car. All I can say is after one cleaning and clutch rebuild, I'm switching back to BL.

Yes I have seen the new 32 series, there are no specs on them, and I have no idea what Ah rating they are. I would assume that they are larger electric car batteries, so you don't need as many smaller cells.. Yeah they have the 'HD' and the 'Ultra', each having higher power OR higher energy density compared to standard M1 chemistry. Ultra being high power, and HD being high energy.

It looks like the Ultra has 50% higher pulse power as standard M1.

It's not just the external BEC/servo, the esc has a certain leakage current inherent as soon as the battery is plugged in.
