Thanks, JB👍

Hi Trev, I use the small battery alarms in all my models, (like the type rooky sailor mentioned.)
They can be set to a minimum voltage with the button on the end. You can hear them in the planes about 100m away.

JB

Hi JB,
Do you use a low voltage alarm on your boats when operating them?
Trev

Try this one Dave, it's main purpose is to protect the lipo cell charge when in the boat, different to the one you use at home to check the balance and voltage.

Cheers, Pete😊

jbkiwi,
That looks like a great meter.
However quite a number of my boats are 2S.
I'd need to add a second power source for the meeter ....

Has out of balance alarm, end of cycle alarm, over voltage alarm etc. Used these for 13 yrs plus the small battery alarms.

JB

Agreed, quite a good reliable monitor, but don't think it has an alarm, not one for putting in your boat when sailing to check for low voltage.

Cheers, Pete

If you want to check the load on your motors, as well as balancing, voltage checking (individual cells as well) these are a great tool if you can find one. I always use these after charging to double check cell balance. Also has a temp port.

Can't beat the price.

mtpurin,
Thank You.
That is the one I have been looking at.
It is good to hear that several of you have experience with it, and like it!

I've been using this type with no issues I would go with this type

Muddy,
Which one?
Dave B

Been using this type of unit for a few years now, no complaints. Very Good.

I have been using lipo's for about eight years now,
and I find these are some of the best, they show you cell voltage and have an alarm when the cell is to low,
this is quite a good deal from an Ebay seller.
Seller might not send to USA but there are plenty on Ebay who will.

Cheers, Pete

Hi Dave,
I don't profess to be very knowledgeable on the subject.
With that in mind I did purchase this on Amazon, seems to work🙄
I went with NIMH in the past because weight wasn't a big consideration, and they are simpler to deal with. The LiPos I have for the 44 I purchased in error, instead of returning them I decided to take the Plunge🔥🔥🔥 (Hopefully not). I already had a charger that can accommodate most Batt Types.
