Battery checker question

[Uncle_buck]

I wanted to get a lipo battery checker and mount it and use it while I run my truck. I'll be running a 4s pack and 2 3s. While I'm running the two 3s packs would I need 2 checkers?

It certainly wouldn’t hurt to run 2 alarms but only 1 is really needed. I only run 1.

your packs should be discharging at the same rate plus your ESC will will let you know when you hit LVC as well....unless you are running 5S on the BLX185 in which case you have to rely on the external alarm since it doesn’t recognize 5S for some reason.

I use mine as a warning alarm on all of my rc’s other than my Kraton when running 5S. I set it at 3.6V.

So don't bother getting one unless I'm running 5s pack in there

No, I would recommend getting at least one. I still use it when I run 4S and 6S packs too. It has a really loud alarm that you can hear from far away. I set the LVC at 3.6V which is .2V from the BLX LVC, once I hear the alarm I know I have time to bring it back to me and not hit the 3.4V. 3.4V is kinda low and if you don’t realize you have hit LVC for whatever reason, you could drain them to a point that causes damage to the pack. It’s cheap insurance.

I use the “cased” Venom lipo alarm on my RC’s but have a non cased that I keep on hand at my tool box. I use Velcro to fix it to my chassis and it has held up to water, dirt and mud really well.

Cool thx that's the same one I was gonna get .

No problemo. I would recommend securing in some way. It has a little bit of weight to it so it could easily disconnect during a hard hit and you wouldn’t know it. I use Velcro and have been really surprised how well it has held during some gnarley wrecks.
