I decided to go for a bit more powerful charge setup. My Dynamite is an excellent unit and I like it but its limited to 8amps... With the 2S packs I have from SPC and their new 3S packs on the way I could USE more than 10 amps... so I needed to find something with not only more amps available but also the wattage to back it up. There simply isnt a charger on the market right now that has a built in power supply that can supply more than 100watts... and thats not enough.
So, heres what ive purchased:
Protek Super Pro 20, 20amp, 260 watt PSU
Protek Prodigy 610 Duo Charger
The charger has dual charge outputs and is capable of supplying 200watts EACH if the PSU can supply it. In this case, the 260watt PSU I bought would be capable of 130 per pack. Which is enough to charge TWO 5000mah 3S packs at 2C at the same time. It will also charge my 6000mah 2S packs at 2C all day long and not break a sweat. And since the charge ports are independent I can charge one 2S and one 3S at the same time at different amp settings.
This was something I learned as I was researching charge setups and its something few people talk about. Wattage is actually MORE important than AMPS when your buying a charger. This is not some NEW piece of info out there but its new to me and really highlights why a low end charger may not be the right choice.
Lets say you have a 5000mah 3S pack... to charge that pack at 1C (which is safe for any lipo and will result in approximately 1 hour charge times) you need 63 watts of power. Most low end chargers are only 50 watts... which means youd have to step down the charge rate to only 4 amps and therefore increase your charge time.
My Dynamite Passport Ultra is a 8amp 100watt charger. It can easily do my 2S packs at a full 8 amps and a 3S pack at 8 amps... that would almost exactly 100 watts. But, if you look at the specs of MANY 8 amp chagers they only supply 80 or 90 watts... not enough to charge a 3S pack at their claimed 8 amp rate.
I just thought this was interesting info. We always talk about how many cheaper chargers are 5 amp capable and are "good enough" but question is... are they REALLY?
Sorry to ramble... just spouting info Ive been learning the past few days.
