Nifty. That looks like a good piece of equipment.

Some more MaxAmps 5Ah 3S pack puffing.....

I've got 2 3S MaxAmps 5Ah packs that I've been using for not even a year. They've got maybe 30 - 40 cycles each. Since I've put in the RCM extended chassis on my CRT.5 and went up to 30 series tires my Amp draw has gone way up and runtime gone way down. I know peaks are hitting the high 90s, but the packs are lasting no more that 10 minutes. That's an average of (60/10)*5=30Amps.

30 Amps continuous (really a 6C rating) and at the end of one run a pack was reading 130* and was puffed out on both side. The puffing went down as the pack cooled - but I sat there and watched th pack for about 30 minutes - I was afraid to put the pack in the car for the ride home.

Very disappointing - I have already ordered a 3S 3900 (25C) Neu pack - so we'll see how much better it does when it comes in.
