Great little battery for my elf plan to use in other model builds. First class service from hyper flight.
Review by: Keith BurrageExcellent battery
Bought as a backup for my Elf. Good physical fit in the nosecone, great little packs!
Review by: Dave PhippsPerfect fit for Elves
A perfect fit for the Elf DLG and quick delivery from Hyperflight.
Review by: Mark.Good for your ‘elf!
Super little 2S, running super little SD100’s, in a super little Elf. Battery at 3.7v per cell after 1.5hrs flight in buffety conditions! Ensure to mount square so as not to foul the nose cone. I didn’t and had to live with a 1mm gap between cone and body joint. Good online ordering/ dispatch service with neat packaging. Thanks Neil.
Review by: MarkGood batt for elf
This batter just fits in the front of the elf. It's a tight fit though. I took the blue cover off it to save a gram and to make the fit easier.
Review by: Ian SantGood battery for the Elf
I bought this battery for the Elf DLG and it is just about perfect. A bit of a squeeze but the battery fitted into the nose cone without removing the balance plug after I shortened the leads to the main connector so it could lie under the servos. I charge it on the 150mAh setting as none of my balance chargers have a 175 setting.

Like everything I have from Hyperflight these are good quality and easy to obtain
Review by: RedhotpheasantGood as an alternative
Does what it said on the label, nothing more nothing less. Was a millimeter too wide for my Elf nosecone and the sharp corners slightly deformed the nosecone when in place (and yes the battery was as far back as possible. A good battery for the price but my recommendation would be to break the piggy bank and go for a Smart LiPo - you won't regret it.
Review by: David HoggGreat battery for Elf
Bought this for my Elf after my SmartLipo starting giving me poor flight times of <30 minutes before beeping.
I stripped off the heatshrink, unsoldered the connectors and soldered my own connector onto a short flying lead, epoxying it to the non-tab end of the battery. I then epoxied a mating connector to the top of one of the servos in the Elf avionics bay, allowing me to plug-in and un-plug the battery with ease, and without fiddling with any wires.
The battery seems to be performing very well, and based on the flight times I've had so far, I should get around 1h30m to 2 hours per charge. With the batteries this cheap, I bought two, which should give me plenty of flying time per session!
I'm using a FrSky FASST-compatible TFR4-B 4-channel micro receiver and two Ripmax SD100 servos - both of which can run directly off 2-cells.

Great for the Elf. Fits as is above but you can shave off 3 grams by taking off the cover and soldering a lighter connector on. (Not neccessary but it was fun!)
