Battery 101

EVE35V-FTU

EVE 35V 3500mAh 10A 18650 Li ion battery with solder tabs (U and Z style tabs)

Style

These EVE 35V 18650 tabbed cells are grade A cells and not rebranded. They perform better than the LG MJ1 and as well as the very popular Sanyo NCR18650GA. This makes these cells ideal for battery packs due to their consistent SoC (State Of Charge) voltage, internal resistance, capacity and performance.

With a maximum continuous discharge current of 10A, this makes these cells ideal for battery pack builders.

⚠️ Note: Always use with a proper Battery Management System (BMS) to ensure safety and longevity. Avoid overcharging, over-discharging, or exposure to high temperatures.

This cell is unprotected and intended for use in protected battery packs. In order to operate safely it must have additional protection in the form of a protection circuit board or a Battery Management System. 

Usage & Charging

!!!!! IMPORTANT!!!!! These are immensely powerful batteries, and extreme care should be taken using them. Only use with brand name, quality chargers and equipment! Unfortunately, we cannot replace batteries that are damaged by non-compliant chargers or equipment. There are so many chargers on the market, we cannot possibly keep track of which ones will work with these batteries. You will have to contact the charger manufacturer to ensure it can charge these batteries without damaging them. Please ensure you only use these (or any other Lithium Ion) batteries with proper Lithium-Ion chargers and equipment. Lithium-Ion batteries can easily be damaged by charging them with too high current or exceeding the maximum rated current discharge. 

Use at your own risk. We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!

  • Do not overcharge! Ensure the charger voltage does not exceed the batteries stated full charge voltage.
  • Do not over-discharge! Ensure the equipment you use do not draw more current than the batteries “Maximum Continuous Discharge Current”.
  • Do not leave batteries discharged for a long period! Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
  • Do not short circuit your batteries!  Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your equipment, and even cause serious injury to you!
  • Do not let your batteries touch each other or other metallic items! Keeping your batteries loose, such as in your pockets, is a serious way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe.
  • Do not dispose any battery in a fire! There are dangerous chemicals in batteries. If you try to burn your batteries, they will release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling centre.
