BATTERY INSTALLATION
Batteries may be installed on either the top or bottom of an ALTA 8 and are always
mounted opposite of the payload location. In both locations, battery packs are
secured with silicone straps tensioned across the packs. The straps are secured
using studs located on either side of the packs.
WARNING
Always secure battery packs with both battery retention straps.
CAUTION
Ensure both battery packs are at a similar state of charge (a
full pack voltage difference less than 0.5V) prior to connecting
them to ALTA 8. Plugging in two dissimilarly charged packs
could cause one pack to rapidly discharge into the other
and damage the batteries or cause a battery fire.
CAUTION
Only use packs that are identical in their capacity and at a similar
condition. Using a pack with another that is larger, or has many
more charge/discharge cycles, can damage the battery packs.
CAUTION
Always refer to and follow the battery manufacturer’s instructions,
recommendations and guidelines for battery handling.
CAUTION
When plugging in battery packs, ensure the polarity is
correct. Positive is indicated by a red power lead, and
negative/ground is indicated by a black power lead.
Reversing polarity will damage ALTA 8’s electronics.
