So I have a Blade SR charger that charges at the same voltage, but only 0.8 amps. The 450X charger charges at 1.8 amps. Would the Blade SR charger be fine for charging my 450X battery?

I know it would be sloowwww but would this work and be ok for my battery? I have a turnigy charger coming in but it's gonna be a while and in the meantime charging off my car battery is inconvenient.

Thanks :peace

As long as it's a 3cell battery charger, it should work just fine. But like you said, it will be sloooow.

I thought the 450X came with a charger.

I tried it. It's not enough amps. The lights blink in a error sequence and the fan pulses. The charger for them450 battery needs to have at least 2 amps I believe. Although it may be 3 amps. Hope it helps.

Thanks irs5. In focus, the 450x doesn't come with a AC adapter. Can only charge off 12V DC. Thanks guys

My LHS had the AC adapter for the 450X charger in stock for $29.95, it works well (although I hated paying that much for it). I ordered a iCharger and MeanWell unit from epbuddy.com last night so that I can charge in parallel.

Just curious, is the AC adapter the same one that comes with the Celectra chargers for the 120SR or mCPX? If not, do you have a part number?

The AC adapter is different. It supplies higher power to the charger to comply with the bigger demands of charging the batteries.

Part # : EFLC4030 Blade 450 Charger 3.0-Amp 100-240V (Adapter)

I actually just used an old Toshiba Satellite power supply. It outputs 12v at 3.3-amps. Perfect and cost me nothing :)

Only bad part is it's not the most snug fit in the charger. If you start moving the charger the plug will slip out if you aren't watching. Other then that it works fine.

Just picked up the official one; LHS had it in stock for $22, and all of my laptop chargers appear to be 19V @ 4.7A... hate to over-volt and let the magic smoke (and fire) out.

Added bonus, they finally had 2mm solid CF rod stock come in, so can start messing with my mCPX tail boom length. Still no 3mm though for a new mainshaft. :( And no 450X tail support strut spares either (3mm CF rods with much tighter manufacturing tolerances).
