Jeti Li-Ions to power the turbine???
I was looking at the specs of their batteries and it shows that a simple 2600mah pack built out of their 2600A cells is capable of 30 amps continuous. Has anyone used them in a 3S configuration to power the turbine/fuel pump? For my next build I am looking to step away from lipo because I don't want to have to remove batteries to charge, and LiFe are not an option as I want the full 8+ volts for my servos and need the full 11+ volts for the Swiwin ECU. I am just not exactly sure how many amps the pump pulls at full throttle and if the voltage of li-ions will stay high enough. I was looking at something like this, in 3S2P:

Bodyworks,
I run these Jeti Li-Ions in all of my models and never have a problem.
On my little Savex L-39 with an MW-44 I run just one 5200mAh battery and run everything (radio, retracts, brakes and engine) from it. I can fly all day on a single charge, at least 6 engine starts.
On my Ultra Flash and Hunter, both powered by a Merlin 140XBL, I run twin 5200mAh batteries into either a CB200 or a CB400. Both batteries go to the CB for the radio system and one battery also powers the engine, and the other also powers the retracts/ brakes on the UF and lights on the Hunter. I can get 4-5 starts & flights before needing to re-charge. A failed start is the indication. If the engine can start, you have plenty of battery to fly on either model.
These Jeti Li-Ion batteries are my default power system. There's hardly any self discharge and they hold charge for months, plus no charging safety issues. I don't run Li-Po at all. Never had much luck with them.
You charge them using the Li-Po setting on the charger, not the Li-Ion settings.You won't get full charge on the Li-Ion setting. That was my initial mistake. Battery internal circuitry protects them from over-charging using the Li-Po setting.

Guys
Li-ion batteries are the same as lipos but with a different skin.They both charge to 4.2 and don't like being left at full charge for long periods. Li-ions are lighter weight for the mah and the metal casing makes them more robust. They can also tolerate being discharged to a lower level compared to lipos. So they do make for a great receiver pack. But you need to charge them like you would a lipo with balance lead connected. and treat them as you would a lipo.

My Feedback: (1)
I make batteries packs from Samsung 40T 21700 cells. They work fine for turbines. They are used for power tools and charge to 8.4V using the LiPo setting. I think they are a better, safer and more reliable battery than any thing sold for RC. At one point Tesla was using them.
