Do I "Have to" use an expensive li-ion charger for li-ion battery packs? Answered
I am building a 7.4v Li-ion battery pack (7200 mAh) with a PCM of course and i usually use my li-ion / liPo charger but i was curoious if their was another way.
this battery pack will be installed in a portable gaming device and i want it to have its own wall charger. But i dont want it to take 6 hours.
I want it to be reliable and I want it to charge fast.
Most li-ion wall charger units for 7.4v only charge at 1.2A max, and charge at up to 8.4V. (And are like $25+)
PCM can handle much higher, up to 8A rate
Batteries are Rated up to 3.5A rate
If I purchased 3 regular everday wall chargers, rated at 7.5V @1A (for $5 ea) and ran them in parrallel in a nice enclosure running one charging plug, (hypothetically it "should" rate; input: 120V, output: 7.5V @3A). Could i use this to charge the for-mentioned Li-ion 7.4V 6400mAh battery pack in just over or around 2 hours???? Or is this not feesable for some other reaon???
