Question: Can you use the 8.4V charger that comes with the Thompson M1A1 airsoft gun to charger this battery?
Document: I used this in my full metal Cybergun Thompson M1A1. It is a considerable upgrade form the typical 1200 8.4v that comes with the gun. it fits perfectly, although being a little bigger than the old battery. It increase the ROF considerably, and also boosts the speed of the BBs in flight. At first, I was forbidden to use it because the upgrade now outclassed the more expensive M4 my brother had, and was considered unfair.
The 9.6v battery works fantastic with my electric airsoft Thompson machine gun. The additional battery cell (8 vice 7) provides just enough extra power to prevent jamming and malfunctions. I highly recommend upgrading your 8.4v batteries the 9.6v.
I charge my battery with a smart charger the night before and it lasts me all day when I go airsoft, a good 4-5 hours of use for sure (I unplug it from my gun in between games). Fits very nicely in the stock of my gun and gives a good firing rate and power.
I use this battery in my Matrix CYMA CM028 AK47 airsoft gun. It's I dentical to the Tokyo Mauri and most other AK47's on the market. On to the battery. It is a small type 9.6v battery with 1600mAh by Tenergy. I upgraded to this from a 8.4v 1200mAh, and I must say, it was well worth the money. We airsoft for about 3-4 hours at a time, and this battery hasn't failed me yet.
I bought this for a replacement battery after the Umarex H&K; G36C (Wallyworld Version) came with only a 9.6V 300mA battery that didn't last 2 hours of game play. I bought a smart-charger with it and charged all 3 batteries I was going to test. So far I've used them in the G36C, a full-metal Thompson Sub-machine-gun, and a CYMA full-metal M14 and they rock.Get out and play!
Play airsoft alot and by using this battery instead of the one that came with my aeg tommy gun i could shoot faster and it would last longer, then if it ran out i could use my old battery.
Stomps my 8.4V battery to a PULP. I've only used it for an hour... but the rate of fire is already doubled. Love it!
Well I'm new to 9.6v batteries for my airsoft guns (I usually go with 8.4), and I must say I am impressed. It's OK that it takes about 45 minutes to an hour to charge with a smart charger on the 2.0A mode because it lasts for a very long time. 2 of these will keep you going for an all day airsoft war with no breaks.
Overall, I'd recommend this product for sure. I never tried any other brand because there is no need; these work fine and are a great upgrade from 8.4V.
After a year of constant use in one of my airsoft AEG's all I have to say is wow! For a $20 battery to preform so well is impressive to say the least. As a 9.6V battery it smoothly doubles the rate of fire for any airsoft AEG I plug it in to. The battery earns 5 stars hands down.
