I definitely wouldn't try switching them since it's a lithium ion battery - it could seriously overheat and cause a fire. **Q: Will this battery fit any battery holder available elsewhere? Can I possibly buy a battery holder that will fit this? Thanks!** A: not sure I drilled a hole in an old plastic file card holder and secure all wiring inside and feed the solar panel there also **Q: Is there a battery holder that fits this?** A: Hello, This pacakge including a 12V 5200mAh battery and a battery charger, there is no battery holder inside the pacakge. Thanks KBT Team **Q: If I was to cut the female end would the bare wires be capable of charging and dispersing power? Or does it need a separate input and output?** A: Hello, The female DC5521 plug is for charging only. The bare wires includes positive pole and negtive pole to provide electricity to device. If you cut the female plug and you need to charge the battery in 12V supply. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Awesome *by J***N on July 9, 2026* These batteries are great for life span, I can power a micro PC, vr camera, and 2 screens for 4+ hours using a 4to1 dc5521 cable. ### ⭐⭐⭐⭐⭐ Get a charge out of life *by W***R on August 21, 2026* Used this for over a year without a problem. ### ⭐⭐⭐⭐ It works but..........................really deserves 2 stars! *by S***A on November 26, 2024* I have 2 of these in 2 different sizes and while they work and do charge to 12.6v they seem like they must be made from extremely old or reject cells possibly because they do not hold a charge even when not used very well. So you have to charge each time you want to use and the runtime is lackluster. These are not rated at what is claimed although I did not do a thorough test. Sadly I am going to attempt to start making my own battery packs with quality batteries because there are so many scam pack out there. Stay tuned perhaps soon I will be making custom quality packs for your devices that are as good as they can be!!! ## Frequently Bought Together - KBT 12V 5200mAh Rechargeable Li-ion Battery, DC5521 Male Connector, Replacement Battery Pack with 12V Charger Compatible for 12V Device RC Car, Boat, Robot, DIY, LED Light Strip, CCTV Camera - (Real 18AWG) 10 Pairs 12V 5A DC Power Pigtail Barrel Plug Connector Cable, 2.1mm x 5.5mm Male Female DC Pigtail Connectors for CCTV Security Camera and 12V Power Supply Adapter by MILAPEAK - LUORNG 5Pcs 10A DC-099 Power Jack Cord Socket Threaded Female Mount Connector Adapter with Pre-soldered Wires and Waterproof Cover Cap, 5.5 x 2.1 MM --- ## 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.no/products/538356120-kbt-12v-5200mah-rechargeable-li-ion-battery-dc5521-male-connector](https://www.desertcart.no/products/538356120-kbt-12v-5200mah-rechargeable-li-ion-battery-dc5521-male-connector) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-22*
