1. Loosen the four thumbscrews on the battery hatch
and remove it from the hull.
2. Loosen the hook and loop straps, and install the
fully charged batteries fully forward in the battery
compartment. Secure the batteries with the hook and
loop straps.
3. Connect the batteries to the ESC.
WARNING: When using two batteries, always make
sure the batteries are of similar type (voltage and
capacity). Connecting batteries of mismatched capacity may
result in battery over discharge, which could result in fire
causing property damage or personal injury.
Positioning the Battery Packs
Toward the Bow: In rough water or strong wind
conditions, place the battery packs at the front of the
battery trays to ensure the greatest stability.
Centered: Smooth water and calm winds may allow you
to move the battery packs rear-ward in the hull to allow
the bow to ride higher and increase speed. Be aware that
positioning the batteries farther aft increases the likelihood
of the boat blowing over at speed or becoming unstable.
Toward the Stern: Positioning the batteries all the way
back in their trays may provide higher top speeds but can
cause instability. Experiment with this position only in very
calm conditions while closely monitoring the hull’s attitude
as you increase speed.
The Blackjack 42 provides ample space for large batteries.
Use two 4S 5000–9000mAh batteries with 100C or greater
for optimal performance.
We recommend using 2–4 4S 5000mAh Smart batteries
(SPMX54S100H5). A Parallel Y-Harness with IC5
(SPMXCA509) is required (sold separately) for 4 batteries.
Choose a charger designed to charge the recommended
Spektrum™ 14.8V 5000mAh 100C SMART LiPo batteries
with IC5
®
Connectors (
SPMX54S100H5
).
We recommend the Spektrum SMART S2200 G2 AC
2x200W Smart Charger (SPMXC1010).
Refer to your charger manual for charging instructions and
safety information.
NOTICE: Never charge a battery in the boat or damage may
result.
