Yet another week, yet more questions….
My friends and I have really gotten into the new Losi Micros Rally/SCT. These things are great on lipo! Since the batteries are so small (using FlightMax 350s – perfect fit!) we were wondering if we could make a harness to charge two of them at the same time. We’d set the charger at 4S. We’re not quite ready to step up to a multiple charger solution.
Thanks, and happy bashing!
Cubby- Hey Tor, as much as I love to hate on Losi, I gotta give massive love to those Micro SCT trucks. We had some of’em in our booth at iHobby and those lil’ suckers are addicting.
Now, as for charging your two 2S 350 mah packs in series, here’s a simple answer- don’t. Yes, you “could” do it, but unless you make an adapter that goes from both your packs balance ports to a single 4S balance port that plugs into your charger, you are at risk of overcharging one or more of the cells. I know long charge times suck, but charging two separate packs in series is highly not recommended.
If you must charge both at the same time, charge them in parallel. In the case of your identical 2S 350′s, having them in nearly the same state of discharge is a plus, and you’ll be setting your charger to 2S Lipo at .7 amps, with the red/positive wires from both packs going to the positive wire of the charger output, and both negative/black wires from the packs going to the negative wire of the charger.
Now have fast and go fun.
And here’s one I stole from Brian’s email…
“Hey Brian, I just came across your site a few weeks back looking for some info on Batteries and found some awesome info! This week I found some even potentially better info on something different.
I am gathering information and normal guy opinions on the dos and don’ts of opening a new indoor electric track for the winter season as a start. A group of guys I met and I built a 1/2 acre 1/8th scale track a few years back and ran it for a summer until it got too big and had to shut it down do
to neighbors complaining. We had over 60+ members and growing.
