Game Boy Advance USB-C Charging Battery Module V2 - Robot_Retro

My last battery blew out (not from here) and this one prevents overcharging/heating that caused that. It takes a while to charge to full but worth it not breaking and it lasts FOREVER. I am actually happy the old one died. because this is way better. Easy to install as well. hhl has great prices and selection too.

Ultimately, this is currently the most affordable of the drop-in and play rechargeable battery mods for the Game Boy Advance. This is the 2nd one of these I have purchased, and if you are playing on system with any upgrade mods such as an IPS or TFT LCD screen, TV out, or color LEDs, these will both extend your play time and reduce the frequency of the battery power bottoming out, shutting off your system mid-play (which was happening to me on occasion in a console that includes a TFT LCD and a pair of shoulder button LEDs). Dropped this in, booted it up, and enjoyed uninterrupted play with continuous power draw from the battery mod. Great stuff.

I’ve installed several of these in my modded GBA’s and haven’t had any issues. Battery doesn’t pop out and is a slick addition to the unit. Typical charge is lasting me about 4 hrs of continuous gameplay. Excellent alternative to AA batteries

This battery module is fantastic! I put it in a stock GBA (after trimming the battery compartment shell) and it works incredibly well. NiMH AAs would only last a few hours before dying unexpectedly. The LiPo with this pack lasted me a week of heavy play before dying. I only have two small complaints: first, the spring contact forces the pack up, so it often ends up putting pressure on the battery door and causing the door to raise up slightly. This is not really a practical issue, just something that I notice. Second, the charging circuitry maintains a consistent 3.3v output voltage regardless of the state of the battery. This is great for the gameboy, but means the GBA's built-in battery-life monitor (green indicator turning red) doesn't give you any warning that the battery is low. You can work around that by simply plugging it in to charge every now and then.

On a full charge just playing for like an hour or two last like 2 weeks I feel like it’s the perfect mod 👌🔥🔥

Great Battery pack for the price. Very stable battery life. Only qualms are to slight trim the highspeedido shells to fit it in snuggly.
