hardened Battery packs

Alternative to bag system

These hardened acks are larger and therefore reduce the amount that can fit into your housing they are also 150g heavier than the bag system but do provide a far more robust package for those of you needing that ruggendess


Never use lithium ion batteries if they appear to be damaged, do not charge Li batteries in temperatures below zero degrees, ideally they should be stored in an outbuilding at temperatures from 10-25 degrees and regularly checked/charged, do not throw away or burn, charge in a safe area away from flammable materials.
