Frequently Asked Questions
How long does this battery last?
LiFePO4 chemistry is designed for thousands of charge cycles — roughly 5–10x the life of a comparable lead-acid battery. Under normal use you can expect years of reliable service with minimal loss of capacity.
Do I need a special charger?
Yes. LiFePO4 batteries must be charged with a lithium-compatible charger at the correct voltage. Many Blwny batteries ship with a matching charger — check the included items above.
Is it safe to install myself?
For most applications, yes. Blwny batteries use standard connectors (like XT60 or Anderson) and include a wiring guide. If you are unsure about your equipment, have a qualified technician install it.
How should I store the battery?
For long-term storage, keep it at a moderate charge level (around 50–60%), in a cool, dry place, away from direct sunlight and extreme temperatures. Recharge every few months.
What does the warranty cover?
Blwny batteries are backed by a 5-year warranty covering manufacturing defects. See our warranty and returns policy for full details, or contact our team.
