[[!tag tags/rockets]] In my post about [Batteries and Pyro Circuits](http://gag.com/bdale/blog/posts/Batteries_and_Pyro_Circuits.html), one of my suggestions was to remove the protection circuit board from LiPo cells used with [Altus Metrum](http://altusmetrum.org) flight computers. To help out folks who want to do this themselves, I put together and posted a [how-to with photos](http://www.altusmetrum.org/Documents/FixBattery/) in the [Documents](http://www.altusmetrum.org/Documents/) section of our web site.
