Introduction:
THANK YOU
SFK-275HP
Lithium Iron Phosphate
Thank you for purchasing your Sun Fun Kits battery kit system, your battery has been hand built by Sun
Fun Kits technicians in our Baton Rouge (Louisiana, USA) facility using components from China, United
States, and India. We have tested your battery by performing a complete balance, capacity, and load test
to ensure it is built to industry standards. Your battery comes ready to use and we recommend you review
this brief guide on how to get the optimum performance and longevity of your unit.
We have built the SFK-275HP battery to be serviceable and upgradeable, this allows for efficient service
and repairs and ensures product longevity. The nature of kit built products comes with some consider-
ations; they are not as rugged as non serviceable products so care needs to be given when handling bat-
tery kits. However non serviceable products generally have to be disposed of in case of issues (regardless
of how insignificant) this contributes to e-waste and is against many right to repair laws; because of this
we feel our kit approach offers the best in reliability and longevity for our customers.
Please review this usage manual before using your battery/kit to ensure many years of reliable use. NOTE:
The battery will arrive at approximately 35% SOC (state of charge) and should be charged to 80-100%
before use. This is necessary to comply with shipping regulations; see the charging section for details.
