The way you recharge your battery impacts the life of the battery.

How frequently should I recharge my 21700? We specifically recommend 21700's because they have the ability to be recharged 300 to as many as 2000 times. You want to select rechargeable batteries that can be recharged many times. They can only be recharged a limited number of times. This happens to any rechargeable battery such as an 18650, 21700, 26650, 14500, AA, AAA or even a car battery. As the battery is reused (recharged), the battery degrades due to oxidation and electro-chemical degradation. The trick is that the bucket also gets filled with other junk over time, so there is less room. How many times can you recharge an 21700 or other battery? But 74 21700 are smaller than three car batteries. In comparison you would need three 12v 40 amp car batteries. So it would take more than 74 of these 21700 batteries to run the air conditioner for 1 hour. A small air conditioning unit that can cool about 9000 BTU uses about 1100 watts per hour. How much power does an 21700 have?Ī 3.7v a 5100mAh 21700 stores about 3 aH to max of 5 aH.

See “ Battery Recycling – How to Recycle Different Battery Types and Corroded Batteries Safely”. If a battery is damaged or looks corroded or appears to be leaking, get rid of it at a battery recycling center. The protected batteries normally have a “button top”, but check the specs to make sure. Unprotected batteries should only be used where the load/draw and charging is externally monitored and controlled. Unprotected 21700 batteries are cheaper, but we do not recommend their use. A 21700 protected battery is safer than an 21700 unprotected battery (less likely to overheat, burst or start on fire). The circuit is embedded in the cell packaging (battery casing) that protects the cell from “over charge”, heat or “over discharge”, over current and short circuit. Protected vs Unprotected 21700 Batteries?Ģ1700 protected batteries have an electronic circuit.

However as expected the stock blaster’s flywheels did shut off if revved for too long and shut off especially quick in my rapidstrike (which is full auto) when fired, except for my worker Hurricane. They bump rate of fire and FPS by about 5-30% with 2 of these and 10-40% with 3 of these in a stock 6V blaster. Sizing of these is pretty much identical to off-the-shelf standard AAs. These work great in my worker hurricane and all of my stock DZ / Nerf blasters.

And do not mix these with standard AAs (alkaline or NiMH) or any other chemistry aside from dummy batteries and LiFePo4 batteries in the same blaster. Do not use on stock blasters that you can’t run the risk of breaking These batteries are safe for YOU, but isn’t guaranteed safe for the longevity of your blaster. Fully charged they are around 4.2V/each, as I have found out from OOD. Shipping price is also pretty competitiveīefore the rest of this review I wanna disclose this first: these batteries are 3.2 volts / each PRE-charged. Shipping was smooth and fast as per usual OOD packaging was good and it comes in the plastic packaging seen in youtube videos.
