[Elecraft] Bioenno Battery Charger

[Jeffrey Wolf]

I previously bought a LiFePO battery from Bioenno along with one of 
their wall wart chargers. I wasn't happy with the setup because the wall 
wart had no user configurable parameters for charging, discharging, or 
cycling. Instead, I tried to use my Turnigy Accucel-6 charger with 
parameters set the way I wanted them to prevent overcharging and balance 
the cells. It wouldn't work because of the internal circuitry built into 
the battery pack. When I contacted Bioenno about this, they affirmed 
that I would have to use their wall wart. Since this was unacceptable to 
me, I sold the battery and charger to someone who wasn't bothered by the 
limitation. I bought a 4200AH battery from Hobby King which is perfectly 
compatible with the Turnigy charger (also from Hobby King) and have had 
no problems since. My advice: If you want control over battery charging 
and maintenance, Bioenno's LiFePO batteries may not be for you because 
of the charger limitation.
