On another note I get some from HK that arrived this week. Dark green PCB and Hobbyking sticker, They seem good and match the readings to 10mv+- on my CellLog 8.

Bulk charge to a comfortable level on a daily basis
Once a week/month/year use a cell level charger like the one Hyena is selling.
Pushing the cells up to 4.2V is a hell of a lot easier than trying to pull them down to 4.2V - especially as our packs get bigger and there is more and more energy to dissipate.
I got out of bed last night and finally finished the design for my new Battery Breaker. It is an aluminum box that gets built into your battery and interfaces with my LVC/HVC boards. It can flow 100A+ to the controller and 50A+ from the charger. If any cell level trips (high or low) the box disconnects your battery completely. No more tapping into the throttle, no more worrying about leaving a controller on. This will be a "real" hardware implemented cell level protection. Ironically - it is almost identical to my HVC Breaker design but with one more set of mosfets hooked up Source to Source. We are going to go with a TO-247 this time around and shoot for 200V+ capability. Going to try and do it by spring time - but the way I have been going... could be spring after next
Anyway back on topic
I would be interested to hear results from anyone who has tried out the newer flavors of this Medic. They are still super small and simple for what they are.
