Why operators make room for it
BLF-1240A KIT (12V, 40Ah LFP Battery): match stored energy to the radio and operating plan
BLF-1240A KIT gives a portable or backup radio station a defined 12V 40Ah LiFePO4 power source instead of forcing the operator to build the power system around an unknown battery. This battery-and-charger package is intended for customers who want quiet, portable DC energy for field operation, emergency readiness, or a station that must continue working away from commercial power.
The built-in protection circuit manages cell balancing and helps protect against overcurrent, excessive discharge, overvoltage, and short circuits. The package includes or identifies the compatible charging path, reducing the chance that a customer pairs the battery with an unsuitable generic charger. Those protections improve usability, but they do not replace correct fusing, cable sizing, connector polarity, ventilation, and load planning.
The real buying decision is operating time versus pack size and weight. A QRP station, a 100-watt HF transceiver, accessories, receive time, transmit duty cycle, mode, and output power all draw energy differently. Honest runtime scenarios, a clear connector path, and the radio-current limits make that tradeoff easier to judge than capacity alone.
Choose BLF-1240A KIT when its documented voltage, capacity, current capability, connector, charger, and expected duty cycle match the station you intend to power. That turns a battery specification into something useful: a predictable amount of radio time that can be planned, carried, and recharged.

Complete product details
The Bioenno Power Lithium Iron Phosphate (LiFePO4) Battery Model BLF-1240A is a state-of-the-art 12V 40Ah battery. The BLF-1240A is a staple of Bioenno Power's high-power 12V battery line designed for more stationary applications and higher power consumption portable electronics requiring a higher capacity and greater power output battery while demanding a battery which can reliably provide excellent performance over an extended service life. 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 an available 110VAC/220 VAC AC-to-DC charger, that provides 6A, with a Powerpole connector. Please note that this battery should be charged using a LiFePO4 compatible charger, and not with a charger for SLA batteries.
Bioenno Power offers a 14.6VDC, 6A AC-to-DC Charger for LiFePO4 batteries, Model BPC-1506A, which uses Anderson Powerpoles for charging LiFePO4 batteries. Please ensure that the LiFePO4 batteries include a PCM/BMS when using this particular charger.
Includes built-in PCM (protection circuit module) which provides internal cell balancing and management, protection from overcurrent, under-voltage (over-discharge), over voltage and short circuiting, and has integrated charging circuitry

IMPORTANT
In practice if you are not using the battery for more than 3 months, simply top off the battery using the BPC- wall charger every 3 months. You do not need to leave the BPC- wall charger attached to the battery all the time. Simply top off using the BPC- wall charger, the LED light on the charger turning from red to green. The 50% rule is only needed if you will not be using the battery for more than 1 year. In that case, you will need to discharge the battery to about 12.8 VDC and then disconnect the wall charger from the battery and store.
