Brand New Ping Battery - Care & Feeding

[pmonkey]

It's good to know that if I am relatively cautious that I'll have a hard time damaging the thing.

And if the ballpark estimate of aH used to get to work is somewhere around 70% of capacity I should be able to avoid draining the thing down to nothing.

But now that I've reviewed my list I have another generic semi battery related question.

I went ahead and got one of the DC-DC converters from Ilia; with the thought of running some 12 V lights via the converter off the main battery.

Is there anything strange or out of the ordinary I should be careful about when setting that up?

I'm sure I will not be doing that right away; I will be more worried about getting the basic system up and running.

Any insight will be appreciated.

Thanks

Set your c.a. to 22amps. for long life, but no higher than 25amp. And your ping will love you. It can be run at higher amps. for shorter life, but more fun. I have run mine at 35a. but it takes it toll and after so time you will be replacing the #16 cell, or worst. Make sure all sense will are well connected.

BEST ADVICE EVER!
I have killed two smaller pings without a CA and/or voltage monitoring. I would just strap my 36c 12ah ping on my ezip and run it! Then I got a 35 amp cyclone setup and that pretty much did both of my smaller pings in My fault though they sure took the punishment for a while.

Yea if you never taste 30mph, 25mph is just fine. I blown up the #16 cell twice. at 35amps.48v20ah Ping. Hills killed it. Flat land is a lot easier.

Yes. hills cause the controller to draw max amps a lot longer. A big part of my conservative advice on low c rate lifepo4 comes from the 1000' of vertical I climb to get home each day.

Over the last few years, I have found that more volts is a good hill tamer. Even 20 amps gets me up hills nice at 48v. And for steeper hills, slower riding with slow speed motors works good.

I think the best thing you did was buy from Ilia www.ebikessf.com real person good man.

I recall reading a few years ago that the charger Ping sent out might have some problems after a few month due to fan failure. The advice at the time was to add a few drops of oil on the fan shaft every few weeks, but I haven't heard of that happening recently. Based on Pings record, I'm sure he is using a better fan now, but it couldn't hurt to add a second fan sometime soon.

pmky, "I went ahead and got one of the DC-DC converters from Ilia; with the thought of running some 12 V lights via the converter off the main battery.

if you want to wire the DC converter in, you can put both the converter and the controller circuit current on that small red wire on the same switch. then connect your batteries up to the large red wires on the controller and run a separate wire to the switch for the controller and your converter. then you can turn off the only current drains on the battery with the one switch, and keep it turned off while charging too. then you don't have the problem of sparking the contacts when you connect the pack up.

Hey,talking about heating issues I think you are a little over worried, as I was recently during my first building:

My 48V20ah Ping is in a box when riding and while charging
and I didn't experience any heating issues at all, temperature inside the box is fresh as it was containing milk.
And this Ping is connected to a 35a infineon limited to 25a, feeding a 9C 2808, who rides me up on very steep hills.
Controller doesn't have heating issues too, even climbing a couple of kms, as hub, both are fresh and healthy.
I guess depends from the entire config but before placing gear in his final place I suggest to run a test ride and see how your system reacts to heating.
You could take a better allocation decision after that I guess.
Life could be easier than you think sometime, run a test ride with really bad looking bike is the best, mine was looking like a washing machine from the back!


Good luck and ride safe!
