Faulty thinking by someone counting pennies... and riding out of a garage daily. $127 here, $105 there and you're already over halfway to the cost of a Satiator, and this doesn't even count the 3 potential fire-bombs strung together "at home". Start with a Satiator, use it on all batteries, at multiple voltages and amps, fully water-proof, physically smaller than most cheap chargers (big bonus for touring), but best of all you don't have to worry about burning the house down with a POS Chinese low-end charger. Most chargers that come with lithium packs are designed to wear the batteries out as fast as possible by charging to the max voltage... they want you to go through batteries quickly. Grrrrrrrrrrrrrrrrrrrreat!
