Matrix High Performance 7.4V Stick Type Airsoft LiPo Battery (Model: 1450mAh / 20C / Flat / Small Tamiya)

"the overall quality of the battery is good the only downside is that the wires are a bit long and on top of that it barely fits the buffer tube (what i bought it for) but if you are planning to put it anywhere else, full stock, etc... this is the perfect battery for you.

"I've received one of those with my air rifle purchase. It arrive dead and wouldn't charge. Contacted customer service for a warranty replacement. Got the 2nd one and it arrive dead and won't charge.

"experience has been a 50/50, we purchased 2 batteries. One works and charges just fine, and another after the second usage almost exploded on us during the second charge using the recommended charger Tenergy v2 per instructions on low voltage charge. Horrible, I will be returning both.

"WHEN these work they are great. So far I've had three and two inflated on the charger and third won't hold a full charge. Nothing against evike as their customer service was great in trying to resolve the issues. It's just that these batteries are garbage. Pay the extra cash and get a better battery.
