| Jul 1, 2016 at 19:41 | comment | added | slomobile | If they claim a 15c max discharge rate for the cells and build in a pack current limiting resistor that limits actual discharge to 10c, they are within their rights to add a safety device. It sounds like your application is fine, you are just upset that you may not be getting the advertised maximum. You won't get it. and that is because the max discharge rate will be limited by your application, not the battery pack. mAh is routinely inflated, prepare to be shocked. | |

If a mfr inflates Ah rating(capacity), then the run time is slightly shorter and maybe a few people are disappointed. If they inflate max continuous discharge rating, and someone actually discharges at that rate, the pack catches fire, burns down a house, maybe kills someone. And mfr said it was safe, so they are liable for damages in court. Max continuous discharge rating is determined by lawyers, not physics. It is a theoretical maximum, not a guarantee. | |
| Jul 1, 2016 at 18:59 | comment | added | Owen Versteeg | I'm not concerned about the Ah rating but rather the max cont. discharge rating. Unfortunately, as long as the Ah rating is above half of its rated value I'll be fine. Typically no company will inflate the Ah rating by that much for the type of battery I have, and if they did I'd be shocked. The max continuous discharge rating is what I'm worried about, as that is a far more commonly inflated number. | |

| Jul 1, 2016 at 18:34 | comment | added | slomobile | @transistor thanks, I did try(unsuccesfully) to add linebreaks to the original with shift- return. You prompted me to look up the correct way(double return). OP stated "Within reach I have a LiPo battery charger (max discharge rate 1A unfortunately)" If LiPo charger has discharge mode, it very likely exists as a consequence of capacity measuring mode. Once you have discharge hardware built in, it only requires firmware to implement capacity measure. | |
