Has anyone used 18650 Li-Ion rechargeable batteries before with the EZB.
I'm using two in series to get 7.2V @ 3400ma, the ones I chose were made by
Xtar and has built-in Protection, ( see photo ). The reason why I wanted to change from the standard 7.4v 1300ma Lithium-ion polymer battery, was the drain rate only gave me about 5 to 8 mins usage, before I needed to recharge, using it on my Hexapod with 20 Protower MG996R Servos.
The Batteries have built-in protection, and have a surge trip protection current of 7 Amps, which I would of thought would of been more than enough to use on my Hexapod, but they trip out on power on, I'm surprised the surge current is more than 7 amps?
The reason I went for these, rather than just getting a larger capacity Lithium-ion polymer battery, was because of the size and weight were small, compared with a polymer battery of 3400ma.
Do you know if these are the protected ones, I think usually ones with soldered tabs aren't protected?
I know these are used in Laptop batteries ( 6 in total, 3 of them in series for 11.1V ) and then 2 packs in parallel to double the current rating. The protection is on a separate board. I have a spare old laptop battery, which I might pull apart and build my own pack, but the weight may be to heavy! *stress*
For the Xtar ones I've seen a test spec of the surge trip protection current being
6.2 amps.
BUT there not good for using with 18x TowerPro MG996R Servos, I'm sending them back....
On EZB power on with servo's connected, the servo's twitch for a milli-second and then the trip protection cuts-in and voltage drops to zero.
I've taken some from a old laptop battery which don't have protection, and these work better, but only 2600ma each one.
By the way there's a lot of counterfeit ones out there on the market!
