If you are looking for eGo/Go-go/510 Batteries, please look in the eGo/Go-go/510 sections, this section is for single batteries for removable units and mods.
Although we carry all kinds of batteries, if you are using a High Drain or Variable Voltage device, like the Lava, we recommend you use IMR Batteries.
We also DO NOT under any circumstances recommend the practice of "stacking" batteries in any of our mods or PV units. Not all batteries work well for all devices, if you are unsure, just send us an email or visit the ECF forums for more information on battery usage.
Please read again..
DO NOT under any circumstances stack two batteries for any reason in any device we sell our current line up is NOT capable of handling blowouts from the use of two batteries and you can be seriously harmed by stacking batteries in mods.
