I recently purchased a Lambo (chrome Lavatube) by L rider. It came with two no name red 18650 batteries. I want to buy two good batteries. I have been reading all available information . Some say that using IMR safe chemistry batteries is the only good option. I live in the Czech Republic and my vendor advises these batteries: Baterie 18650 Panasonic 3100 mAh - www.ecigareta-shop.cz. These are unprotected so I asked him if they weren't dangerous. He answered that these batteries are very stable and were very unlikely to explode or suchlike because the Lambo has all necessary built in protection. He also said that IMR batteiries always have a low capacity and that these unprotected high capacity were the only possibility if I wanted batteries with a capacity over 2200 mah. What do you guys think?
