mattsa80 Posted February 12, 2016 Posted February 12, 2016 having to borrow a rifle from a mate for a game tomorrow and both his batteries are reading low volatge on the balance charger when plugged in. I am guessing this means they are too flat or is therer a way to get some charge into them? 7.4v deans lipos. Any help greatly appreciated.

n1ckh Posted February 12, 2016 Posted February 12, 2016 If he's got a programmable charger then put on balance charge (set the MAH cut off to the MAH rating on the battery) & charge at 0.1 amps (basicly trickle charge) until the display reads 3.60v in each cell & then change to normal charge rate If it's way below 3v then its fooked completely Sitting Duck 1
mattsa80 Posted February 12, 2016 Author Posted February 12, 2016 charger and battery belong to my mate so been used plenty. its an equilibrium mini v2
mattsa80 Posted February 12, 2016 Author Posted February 12, 2016 trickle charge still says low voltage
Supporters Sitting Duck Posted February 12, 2016 Supporters Posted February 12, 2016 is balance board connected correctly ?? other than that watch this vid - ALL OF IT !!! (OK first 1:30 mins the bloke is dicking about a bit but watch the rest for sure) and CAREFULLY start charging to get it above the low voltage mark then it should attempt to work ok note your charger seems to be similar to B6 type but this is best I can offer - be careful and charge in a safe place on worktop in garage or deffo not on floor/bed etc.... hope this works - be careful I know there is a way to force charge lipo's for when some chargers/lipo's only take 90% charge and people top up to near the max 4.2v per cell BUT that is for people who know what they are doing What your lipo's have is a charge below its limit and in vid it will force some juice into them Then it should no longer get error and hopefully charge up normally on lipo program Other than than it is gonna be a case of getting dean-s.tamiya so you can use yours (or fit deans to yours but only if you can solder and cut+solder ONE WIRE AT A TIME)
mattsa80 Posted February 12, 2016 Author Posted February 12, 2016 yeah its charging my lipos okay they are same just not got deans connectors which is what i need
Supporters jcheeseright Posted February 12, 2016 Supporters Posted February 12, 2016 give them a 5 minute bump on the NiMh setting, happened to me loads of times, you just need to get the voltage per cell over about 2.8v and you're good to go. Sitting Duck 1
