I have a powerbox battery 1500 that came with an aircraft last year and which I had the cells replaced in (by powerbox) before using.
All has been well with the battery for months but now when I try and charge it I get the charging led for about 10 seconds then it goes out but I get no green led after it has gone out.
I assume that it is doing this because the charger has detected a fault with the pack.
I have checked the pack voltage and it seems to be half charged (7.6v) but the voltage doesnt increase if its left plugged in.
Is this battery in need of a service or is there a way too reset the charger function to try charging again? I've tried several times but only get the red led for about 10 seconds.
