||I have been using this charger now for about 2 weeks. No complaints. Its great to be able to charge 2 batteries at once at a high charge rate. Listed below are a few observations.
The power. 10.0 amp x 2 without an external power source. Sweet
Can overcharge your battery (good for spec class racing but may damage your battery, use with caution)
Battery memory is a plus but if your only charing lipos its really not a big deal.
It is big. Like you'll probably have the biggest charger at the track
There is not a built in port for rechargeable receiver battery packs
You probably have to solder your own connectors as this only comes with Horizon Hobby plugs
Shop around for a good price on this guy. I found mine brand new for $230.
