Exactly what I was expecting and for that, couldn't have asked for more. I'm glad HH had what I was looking for and will definitely purchase from HH again for future modding and gaming needs!
Everything explained in the product description is clean cut, and I loved my original cleanjuice. However, something I noted between the original, original+low power chip, and V1.1 with built in low power; is how much quieter this one is. The original model introduced some high frequency noise that would come though on headphones or the speaker if it was turned up. The convenience of a long lasting reliable battery outweighed this issue, but it still bothered me. Anyway, V1.1 fixes this and that noise is gone, it's as quiet as if you are using fresh AA's! Essential if you want a rechargeable battery that doesn't undo your audio mods.
The newer version with the low battery indication was well worth the wait. This is an absolute must if you have an IPS modded GBA.
Install was quick and easy, everything fit as expected. My only comment would be that the contacts on the board can actually fit inside of the battery “spring” and not make contact. This is easily solved by putting the contact slightly off-center when installing.
I'm not going to drop a star concerning the lack of a low power trigger since that's since been resolved and there is a board on offer for V1 units. My only nitpick would be that the board in this kit is wafer thin, but the kit does exactly what it says it will do and is an otherwise perfect long term alternative to even rechargeable AA batteries. I will keep buying these kits for all my GBA builds!
The high-capacity Li-ion battery is perfect for IPS consoles, and I appreciate that it's USB-C-- one less device that needs MicroUSB on the go. The only thing I don't like is that RetroSix used tiny battery contacts that don't lock the module into place when seated in the battery compartment; it can be pushed back outward by the spring-loaded terminal. Their solution was apparently to add adhesive to the bottom, which is both silly and adds unnecessary risk of rupturing the battery. RetroModding's battery module, which I also have, has larger battery contacts which interact with the GBA's terminals correctly and fits securely without the use of adhesive. I mention this specifically because HHL advertises this as "better" than RM's product. I'd like to see RetroSix address this in a future revision.
