The Bioenno Power Lithium Iron Phosphate (LiFePO4) Battery Model BLF-1220AS is a state-of-the-art 12V 20Ah battery. Meeting and exceeding the power of a 12V 40Ah SLA at only 7 lbs. for our unit as opposed to 33 lbs. for an SLA, this AS variant offers reliable quality performance in a standard ABS form factor designed to be the ultimate drop-in solution. Ideal for hard use, this ABS version has seen extensive use in science, powering critical avionics on sail planes with additional applications covering e-bikes, e-scooters, radio communications and audio-visual. The battery has an integrated PCM (protection circuit module) which provides complete internal cell balancing, complete integrated protection along with integrated charge circuitry and boasts no EMI/RFI (Electromagnetic Interference/Radio-Frequency Interference) and is absolutely quiet! This unit has available a 110VAC/220 VAC AC-to-DC charger, that provides 4A with Alligator Clips. Please note that this battery should be charged using a LiFePO4 compatible charger, and not a charger for SLA batteries.

GENERAL QUESTION: I noticed the Max and Peak Continuous Discharge on the label may be different from the website and why?
The printed label may be rated to 1C Max Continuous or 2C peak. However, for some models of batteries including the BLF-1212A, BLF-1212AB, BLF-1215A, BLF-1215AS, BLF-1220A, and BLF-1220AS, 30 Amp PCM/BMS boards have been installed. The de-rating on the label to 1C is mentioned to ensure the battery can deliver more than 2,000 to 3,000 cycles. However, rest assured these batteries can deliver the 23 Amps for your ham radio equipment which has a duty cycle of 20% transmit and 80% receive. If you operate continuous at the 2C discharge (with no duty cycle), the cycle life is a bit less to about 1,800 to 2,000 cycles instead of 2,000 to 3,000 cycles.
