Hi Les It means what it says. Good to see a clearly marked battery for once. You can discharge at up to 20 times the capacity 1300x20= 26000Ma or 26amps It claims you can charge at 3 time capacity 3.9amps. Personally I never charge my Lipos at more than the rated capacity 1.3amps in your case. The battery capacity is 1300Mah has 3 cells (3S) and a nominal voltage of 11.1v (3.7v per cell)
Each Lipo should be treated in accordance with its specs. A 2200mah battery may well have a different discharge rate. The dearer batteries usually have higher discharge capabilities. Charging should be done individually and again in accordance with its specs.
Not sure why you are asking the final question but if you are thinking of using two batteries together they should have identical specs. Personally I would advise against this as you run the risk of damaging a battery if all the cells are not balanced, not to mention the risks involved both personal and material.
Hi Les, NONE of the above! It's an EC3 connector. If you are going for hi speed hi amps I would recommend you swap both sides for XT60 or Deans connectors. Pic shows an EC3 (blue) to Deans/XT (red) adapter so you know what they look like. You may find it easier to find batteries with the XT connector. Cheers Doug 😎

Hi Les If you are happy with this connector and your other equipment uses this type I would leave well alone. If you do decide to change then I agree XT60 or Deans are common. Does mean you will need to change all the connectors on your equipment or get converters.
Not sure I agree with keeping Lipos at above storage charge for any length of time. I have had several of mine balloon before I knew better and I was using them every week. I suspect high temperature may be a factor but that's just my opinion. I now make sure any batteries I have charged are used even for a short time just to drop them from full charge. I use the air boat on the bench. I do agree you should use a storage charge if you are unsure when you may use them again.
It get's confusing when in the manual it states... Charge to half capacity after use. But of course, how can you charge it to half capacity, when the charger charges EACH cell separately. It's hair pulling out stage. LOL.
Hi Les Yes I agree there is no way with the charger supplied you can do anything other than charge to full capacity. I do believe we have made suggestions on another thread on the site advising possible solutions. The cheapest would be to just buy a simple battery checker and make sure after you use the battery the voltage is around the 3.7-3.8v mark. Run a bit more to reduce and short charge to increase. If you are intending to become serious about modelling and using LiPos then, like most of us you will want to buy a charger that does the job for you automatically. There is a cost but if you protect your batteries they will last and save you money in the long term. I've not had much hair for some years so probably that's why!
