Default New to lipo

I just got my first lipo, its a 3800 mh. I am using the losi device that uses a reguler charger, I am charging at 3.8 amps but am unsure what to set the delta peak to. I am using a pitbull charger.

It doesn't matter what you set your delta peak at if you are using the losi adapter. Just set it relatively low and your good to go

It is recommended that you balance them periodically. What brand is your lipo?

Balancing is more crucial with 4s. It does not need to be done everytime, especially since your charger will not charge it all the way, there is very little risk of overcharging a cell. Just take a volt-meter to the tap every so often to check the balance of the cells

Use the voltmeter after you've run it and see how close any given cell is to the 3v minimum voltage. Then check it again after charging and see if the low cell is still low. If it is, thats the cell you need to worry about overdischarging below 3v. Some lipos tolerate slight overdischarging and you basically don't have any adverse reactions. Some won't tolerate it at all and will puff or swell.

Charging at lower rates leads to better balanced cells, so if they're getting out of balance from each other, drop charge rate and see if that improves the balance. 4S is an investment and to get the best from it and protect your investment, need to eventually get a balancer.

This is the balancer thats built into the charger I use (0610iNet) - Hyperion LBA-10. You can get adapters for the major kinds of balance taps and it will balance while charging which is best method -

This is another that Hyperion makes for Tower thats also a good balancer (supposed tro be same one, just re-badged for Tower) -

Lipos charge at a 1C rate - 3.8a in your case. Some manufacturers say their lipos are 2C capable. Charge at the higehr rate only if the manufacturer says its ok.

Thats the batt discharge rating - 25 x 3.8 = 95amps. There are usually 2 of these - a continuous and burst (10sec or so) ratings, you mayor may see both listed. If only one is listed its prob the continuous rating.
