Do not short circuit (will release tremendous current)
Do not dispose of in fire

These cells have much lower internal resistance than regular Li-Ion 3.7v cells and they may end up with a higher ending voltage when charged in certain chargers. Please check the voltage of them right out of the charger to see if they are above 4.25v when fully charged. Overcharging above 4.25V may shorten life/cycles. Above 4.50v may even pop them or making them leak. DO NOT use the charger if it seems to overcharge cells.

Video Transcription Hey guys! What's going on? This is Alex. I'm out of Freedom Smokes and today we're going to talk about the Samsung 25R Battery. This seems to be the choice preferred battery among most sub-ohm users for their mods and it really works great in the digital mods also and provides a very long battery life. Now the great thing about these batteries is that you do have 100 amp pulse. I believe it's for a whole 60 seconds so that makes it one of the safest batteries on the market probably right next to the Sony VTC4, but those are getting a little bit harder to find. So I've been just really recommending our customers go ahead and roll with these. The max discharge on this is going to be 20 amps but you are very, very unlikely to reach that spot so this is going to be great for your sub-ohm builds. It is a 2500 mod so it will last a long time in your mechanical mode or pair them up and get real long lasting results with something like 100 Watt box. So all in all, these are more power houses. Make sure you do get the right charger for these. If you've got a little cheapo charger, it's probably going to take forever for these to charge up, so we do recommend something that you can kind of control your voltage input when charging these batteries. Plus you don't want to overcharge them or they'll die quicker. If you have any questions, leave a comment below.
