Convert Ryobi RM300e to Lithium battery

[BillDeLong]

A potential firebomb in your garage. I would store it outside under cover away from your house.

I believe heat is the cause for many of these battery failures, I truly feel that storing the battery at 40% charge inside a cool climate controlled home is the safest option. Under cover away from the home is perfectly fine in cooler months but drastically increases risks with any heat above 113°F, that's the point damage begins to occur and risk of battery fire.

While I choose to store/charge mine inside the house, I would not be opposed to any recommendation of charging the battery in the garage provided you are monitoring the battery while it's being charged.

Of the dozen or so LiPo fires I've personally seen at the R/C race track in my area, in every case they were caused due to some form of negligence from the operator
