hi folks,
tried to find an answer to this on google but only got details about damaged cells and charging of cells.
I have two identical lights I use on the bike, they both have small (fag pack sized) li-ion battery packs that sit in a pouch with velcro securing it to the frame. At the moment i'm mounting both packs onto the frame and that all seems to work fine. However i found an old battery holder that is big enough to hold both battery packs (minus their holding pouches) together so will only need one battery pouch attached to the frame with both battery packs stored in it.
I have been told that this is a big no no by a colleague and they should always be kept separate but i cant find anything online that backs this claim up. Both battery packs are in sealed rubber water resistant cases so the batteries wouldn't be able to actually come in direct contact with each other.
When charging, all my lights are charged on the garage floor in an ebay special ammo box just incase they go pop.
any help would be much appreiated
thanks
No problem there, apart from it sounds like you may be charging packs unattended, a big no no with standard gear... The standard charger still supplies current once the red light turns green, if left for a length of time the battery overcharges and that's when you get the fire.
I've solved that problem myself by opening up the packs and soldering in A remote control style JST balance charge lead, which allows the packs to be charged and monitored by an RC car/aircraft charger that ramps current supply according to state of charge.
