Bioenno 20 Amp-Hour Battery


Model BLF-1220A

This is a Lithium-Ferrous-Phosphate (LiFePO4) battery.  It uses state of the art chemistry resulting in batteries that are both physically and thermally extremely stable.  Importantly they are intrinsically safer than other lithium chemistries because of their strong ultra-stable Fe-PO bond.  These batteries offer many advantages relative to sealed lead acid batteries (SLA).  Here are five top advantages:

·        First, they cannot sulfate, leak,  or vent, like an SLA

·        Second, they weigh about 60% less, and are half the volume, of an SLA

·        Third, charge and discharge life cycles exceed 2000, compared with 300 for SLA’s
·        Fourth, built in protection for overcharging and discharging and cell balancing

·        Fifth, 100% of their Amp-Hour capacity is available, whereas about 60% for SLA’s

Bioenno  batteries are nominally “12” volts.  When fully charged they measure 13.8 volts.  During discharge the voltage will drop very slowly until around 12 volts at 90% discharged, 11.5 volts at 95% discharged, and turning off at 11.0 volts when the full amp-hour rating is reached.  

Bioenno Battery BLF-1220A

This is a 20 Amp-Hour battery.  It is outfitted with a Powerpole connector and a special DC socket to permit connection to our convenient charger. This makes it is ideal for powering radio transmitters for amateur, or general communication It can power a 100 watt transceiver radio for over 10 hours.  Click on "Charger" above to choose either the 2 Amp ($22.00) or the 4 Amp $25.00)   Shipping is by US Postal, PARCEL POST, ground service only
