Review: Nice Battery - I am using this battery as a replacement to the Shimano Di2 system battery on my Trek SC TT bike. The battery fits perfectly in the seat tube for an integrated more aero setup. It is smaller, lighter, and lasts a lot longer than the stock Shimano battery. Review: great fit - This is my back up battery for my ICS CXP 15 fits in hand guard with ease. Just wish i could get these dimensions in 11.1 and higher mah lol. everyone i play with like how small it is and the fact it fits in their AEGs. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.1 out of 5 stars 41 Reviews | ## Images ![Tenergy 7.4V 900mAh 25C LIPO Battery Pack for Blade CX & CX2 Helicopter - Image 1](https://m.media-amazon.com/images/I/61vi+3Dp9vL.jpg) ![Tenergy 7.4V 900mAh 25C LIPO Battery Pack for Blade CX & CX2 Helicopter - Image 2](https://m.media-amazon.com/images/I/71eqVN+ENPL.jpg) ![Tenergy 7.4V 900mAh 25C LIPO Battery Pack for Blade CX & CX2 Helicopter - Image 3](https://m.media-amazon.com/images/I/71gUjucVPvL.jpg) ![Tenergy 7.4V 900mAh 25C LIPO Battery Pack for Blade CX & CX2 Helicopter - Image 4](https://m.media-amazon.com/images/I/717XvpT4F6L.jpg) ![Tenergy 7.4V 900mAh 25C LIPO Battery Pack for Blade CX & CX2 Helicopter - Image 5](https://m.media-amazon.com/images/I/71Mqu1l8CgL.jpg) ## Questions & Answers **Q: Will this fit Blade 200 QX Quadcopter? it uses a stock 800 mah 20 C battery** A: Can the stock charger came with 200 QX charge this? can the electronic system of the 200 qx handle the 25C compare to 20C which is the stock C rating? i hope it wont fry the electronicshows ur fly time with the 200 qx with this battery is it a bit longer than the stock since its a 25C? **Q: Want to connect this to my polarstar fusion airsoft rifle to run the fcu. compatible?** A: Not sure but as ling as voltage and discharge rate does not exceed, I don’t see why not **Q: Tenergy 7.4V 900mAh 25C LIPO Battery Pack works for blade 200 qx? and since its a 25C it wont fry the electonics** A: Yes.

It is smaller, lighter, and lasts a lot longer than the stock Shimano battery. ### ⭐⭐⭐⭐ great fit *by G***. on March 21, 2014* This is my back up battery for my ICS CXP 15 fits in hand guard with ease. Just wish i could get these dimensions in 11.1 and higher mah lol. everyone i play with like how small it is and the fact it fits in their AEGs. ### ⭐⭐⭐ Not a true 900Mah Lipo *by A***H on February 26, 2015* It is not holding much charge when compared to 800mah battery of eflite. Flight times are atleast 2 minutes lesser. But this is cheaper compared to eflite batteries. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/11967987-tenergy-7-4v-900mah-25c-lipo-battery-pack-for-blade](https://www.desertcart.tn/products/11967987-tenergy-7-4v-900mah-25c-lipo-battery-pack-for-blade) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-31*
