I have two 12v-100Ah LifeP04 batteries left over from another project. I tried hooking one of them up to a B300s and while it was working great, after a few hours I went to check the battery voltage and the Positive post and clamp was way too hot. The Negative post temp was room temp along with the battery as a whole. I earlier measured the current draw with an amp clamp meter, and it showed 7.9 amps, which seemed reasonable.
This can’t be good nor safe since it’s a lithium battery. After disconnecting and letting it cool down, the voltage showed the battery was down to only 70% SOC, according the company’s charge chart. I emailed support from the company but haven’t heard back all week.
Anyone familiar with using LifeP04 batteries that could shed some light on this? Maybe the battery’s own BMS is what was heating up?
