Proudly made in the U S A

Elecraft K2 QRP operators have requested a charger that would work well with the 2.9 A-hr gel cell option that Elecraft offers. We responded with our Switchable QRP version.

The "Q R P Smart Battery Charger" has two current settings via a front panel mounted toggle switch

If you want us to do the modifications

We will add the circuitry and a front panel mounted toggle switch that allows you to switch between any two of the following current levels: 1.0 Amp, 3/4 Amp, 1/2 Amp or 1/4 Amp. The front panel will be labeled with preprinted tape as in the photos above and below. The cost would be $10 more than our standard assembled unit. To order specify 150-QRP and specify which two current levels you desire. If you would also like the Anderson Pigtail Option, add $5 more. Allow about 7 - 14 additional working days for us to build and ship your custom QRP Smart Battery Charger.

The cost is $5 more than our standard KIT. To order specify 150-KIT w/QRP MOD. We will drill the extra chassis holes. Items included in the QRP MOD consist of: instructions, toggle switch, extra wire, front panel labels (sticker) and all the resistors required to implement any of the 4 current levels stated above. If you would also like the Anderson Pigtail Option (you assemble), add $3 more to the cost. For more output cable options, see Charger Price List

Many Ham Radio Operators maintain an Emergency Battery Backup System for use during power outages. Quite often Ham Radio is the only source of communication following a disaster. To be prepared, HAMs practice for these events during RACES exercises or the annual ARRL Field Day. Many HAMs depend on our 5 Amp or 1 Amp Smart Battery Chargers to maintain their Emergency Battery Backup System. See the SHORT TAKES review by Joel R. Hallas, W1ZR, ARRL Assistant Technical Editor in the MAR 2004 QST. For full details click here: (Article In Adobe Acrobat)
