But there are some things you have to look into. Look at the physical size of the battery pack. Make sure the new one will fit into the RC unit where the old one went. I have no way of knowing what kind of plug you have on your RC unit. The plug on the new battery may be different. If the plugs are the same then you are in luck. If they are not the same you may have trouble using the included USB charging cable since it plugs into the main plug for the battery pack. As far as the voltage goes, they are the same so no problems there. The higher mah rating for the new battery is OK too as it should last longer than the old one did. Best of luck! **Q: What kind of charger can i use to charge it? Can i use a Samsung s8 plus charger to charge this type of battery?** A: Yes， any Wall USB charger can charge this battery.or power bank or computer USB port both ok,thanks. **Q: Will a 7.2v battery work on a 6.0v car? I was looking to upgrade my battery pack.** A: Not work, if same SM-2P plug, 6V NiMH battery choose below link: https://www.amazon.com/dp/B07PY8R3F4?ref=myi_title_dp **Q: Le sirve aun carro decintrol remoto escala 112** A: Si me funcionó y estoy contento con el resultado de esta batería. ## Customer Reviews ### ⭐⭐⭐⭐⭐ WORKS GOOD *by A***N on September 28, 2024* NICE BATTERY ### ⭐⭐⭐⭐⭐ Great Battery for Projects *by P***L on December 20, 2019* Great power source for all types of projects. Used it with two servo motors requiring high stall torque. Battery lasts a long time and easy to recharge. Just be careful with the pins in the charging cord to not break them. ### ⭐⭐⭐⭐⭐ Enough time *by M***Y on April 27, 2021* This battery got the job done. My son got his remote car in christmas however the run time it came with was just 5 minutes run time. So i was considering buying a new car then someone suggested buying a battery with more MAH. This indeed was successful. It has been 2 days since i received it and he's using it without complaining. Charged twice since and no issues. Value for money. It came with its own charging cord also. Happy. ## Frequently Bought Together - Blomiky 7.2V 2200mAh Ni-MH Rechargeable AA Battery Pack with SM-2P Black Plug and USB Charger Cable for Old Version 15 Channel 2.4G Huina 1550 550 RC Excavator 7.2V NiMH - Blomiky 6V 2200mAh Ni-MH 5 AA Rechargeable Battery Pack with SM-2P Black 2 Pin Connector Plug and USB Charger Cable for RC Truck Cars Vehicles 6V NiMh - Gikfun JST SM 2-Pins 2P Female & Male Plug Connector Wire Cables for Arduino (Pack of 10 Pairs) AE1045 --- ## 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.us/products/121656197-7-2v-2200mah-ni-mh-rechargeable-aa-battery-pack-sm](https://www.desertcart.us/products/121656197-7-2v-2200mah-ni-mh-rechargeable-aa-battery-pack-sm) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-21*
