Will the StratoLogger logic function using a Lipo 3.7v cell? Anyone tried this? I'll be using the Quest Q2G2 igniters for e-matches.
Thanks!
Thanks!
Power range is 4-16 Volts. A 3.7 LiPo will get slightly above 4 volts when fully charged but I'd go with a 2-3S battery to be safe. I've run SL100's with Turnigy LiPo's and they work great.
These are what i use with my stratologer https://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=23135 also get jst plug sets for conecting the battery and charge leads(at least one) https://hobbyking.com/hobbyking/store/__9682__Male_JST_battery_pigtail_10cm_length_10pcs_bag_.html and https://hobbyking.com/hobbyking/store/__9683__Female_JST_battery_pigtail_12cm_length_10pcs_bag_.html
Yeah that one would work great. You could even go smaller if you are pressed for space, the idle power draw on the altimeter is incredibly tiny. As long as you get one that can pull a couple of amps for the charges you should be set, Q2G2's have relatively low amp requirements. A word of advice - if you are ordering from Hobby King try to find a battery that is in stock in the USA warehouse, instead if the International warehouse if possible. The shipping is way faster/cheaper.
Lipos are great, I use them for my launch control battery and FE (fast electric) boats. One thing I would like to add if someone looks at this thread and hasn't used or isn't familiar with lipos is not to over charge them. Maximum charge is 4.2 volts per cell so a 2s would be at 8.4 volts. Also do not discharge them below 3.0 volts per cell or you run the risk of them being damaged. The best for charging lipos is to use a proper balance charger. Hobby king has some very inexpensive balance chargers for lipos that I would suggest to use if you go the way with Lipos.
A good cheap balance charger for small capacity 2-3cell Lipo packs is this - https://hobbyking.com/hobbyking/sto...3S_Balance_Charger_Direct_110_240v_Input.html or for feild chargeing - https://hobbyking.com/hobbyking/store/__7637__Turnigy_balancer_Charger_2S_3S.html or this https://hobbyking.com/hobbyking/store/__14633__HobbyKing_E4_Balance_Charger_.html (I have and use this and the mains powered charger mentioned first, both work great)
I would personaly go with the third choice charger, https://hobbyking.com/hobbyking/store/__14633__HobbyKing_E4_Balance_Charger_.html
The batteries we are talking about above are below 1 amp, when charging these small batteries I would suggest to charge them no more than at a rate of 1C, this means that a 160 mAh lipo would be charged at a rate of .160 amps, or the 0.1 amp setting. you will get the longest life out of these batteries if you can stay in the 1C rule of charging.
This looks to be a very good charger also and gives you more options and a digital screen so you know whats going on. https://hobbyking.com/hobbyking/sto...m_Polymer_Battery_Charger_USA_Warehouse_.html it also will allow you to charge your batteries to a storage charge of around 3.85 volts per cell to get the longest life out of your lipos if they are not used over an extended period of time.
I use the little 200mah one of these.

I get a good quality Deans and 6.6 volts. And the safety of a LIFE.

Have you a recomendation for the charger? I looked at a few, but I really don't know anything about them. Thanks!

This battery shows a max bust discharge rate of 40C, which according to the website's table equates to 200,000 miliamps, or 200 amps. Is that correct? If so, seems like that's way too high for our uses.

The primary advantage of the LiFe battery is that you tend to get more cycles out of the battery as compared with LPo or Li-Ion batteries.I use the little 200mah one of these.

If you don't have a 12volt power supply you can use an old computer power supply which will give you constant 12 volts. You can also use a 12 volt vehical battery.
