I picked up some tiny single cell charger boards with built in low voltage cut-off to make a tiny battery pack. Worked like a champ! Review: Last twice as long as original battery. - I swapped this battery in place of the OEM unit and I’m genuinely impressed — it works well, and it stays charged significantly longer than what I had before. The build feels solid, the voltage holds steady, and it gives me peace of mind that I won’t be scrambling for a recharge mid-use. If you’re looking for a dependable replacement that punches above its pricing tier, this one’s a great pick. ## Features - Make Sure Device Polarity Matches with Battery Pack Connector Before Purchase-1.Battery Size; 2.Connector Model; 3.Connector Size; 4.Connector Polarity - This is not universal(It will cause a shortage if the polarity of the battery connector does not match your device.) - Basic Info—Voltage: 3.7V; Typical capacity: 1100mAh, Min capacity: 1000mAh; Weight: approximate 22g; Size: 34.5 x 51 x 6.3mm (WxLxH).

I picked up some tiny single cell charger boards with built in low voltage cut-off to make a tiny battery pack. Worked like a champ! ### ⭐⭐⭐⭐⭐ Last twice as long as original battery. *by T***L on October 30, 2025* I swapped this battery in place of the OEM unit and I’m genuinely impressed — it works well, and it stays charged significantly longer than what I had before. The build feels solid, the voltage holds steady, and it gives me peace of mind that I won’t be scrambling for a recharge mid-use. If you’re looking for a dependable replacement that punches above its pricing tier, this one’s a great pick. ### ⭐⭐⭐⭐⭐ Actually 1100mAh as it is rated! *by P***Y on May 2, 2023* I used this to replace a battery in my Sony Dualshock 3 controller for my PS3. I needed a battery and didnt want the standard size official Sony battery as theyre very small, in the order of 500 mAh or so. I installed this and it fired right up even without charging it which is a good sign. It takes twice as long to charge the controller now, but it lasts seemingly forever now. ive used it daily for almost 2 weeks now and it still says I have 2/3 charge. I would highly recommend this battery to anyone looking to do the same mod. It fit in the old battery spot perfectly fine, but I did place a bit of foam between the motherboard and battery to keep the solder points from poking the battery body. ## Frequently Bought Together - EEMB Lithium Polymer Battery 3.7V 1100mAh 603449 Lipo Rechargeable Battery with Wire JST 2.0mm Connector for Speaker and Wireless Device- Confirm Device & Connector Polarity Before Purchase - HiLetgo 3pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions - elechawk 10pcs Upgraded Tiny Whoop JST-PH 2.0 Male and Female Connector Cable for Battery JJRC H36 H67 Blade Inductrix E010 E013 --- ## 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.com.kw/products/282474582-eemb-3-7v-lipo-battery-1100mah-603449-3-7v-lithium](https://www.desertcart.com.kw/products/282474582-eemb-3-7v-lipo-battery-1100mah-603449-3-7v-lithium) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-13*
