搜索了几个帖子，但还是有些疑问，就是那种电动车的12v电瓶直接连在电台上是不是也可行

又看到一贴说可以用磷酸铁锂大单体电池

@"BG2GYS"#p93444 看电瓶参数，查放电电流

@"BG7PUW"#p93448 在淘宝上看到一款12.8v18ah的磷酸铁锂电池带20A保护板，这个达不到说明书上至少23A的要求，影响大吗？

@"BG2GYS"#p93451 那就可能发射功率不够，电瓶满载

@"BG7PUW"#p93455 带 30A 保护板的版本倒是最大持续放电是30A

满功率可能不行，选个 30A 保护板的吧

按照满载来买，我自己做的15Ah用的30A保护板，50Ah用的50A保护板，反正满足最大发射电流就行

电瓶车蓄电池我之前用过可以，接个小电压表别过放了就行，但对电压敏感的机器功率跑不满，设定100W出80-90W这样。锂电池保护板限流，按照电台标明参数留点冗余

Problems with the power supply of the FT891.

BG2GYS

I searched through several posts, but I still have some questions. Specifically, can a 12V battery for an electric vehicle be directly connected to the radio antenna?

BG7PUW

BG2GYS Based on the battery specifications, determine the discharge current.

BG2GYS

I also saw a post mentioning the use of large-format lithium iron phosphate batteries.

BG2GYS

BG7PUW I saw a 12.8V 18Ah phosphate iron lithium battery with a 20A protection board on Taobao. This doesn't meet the minimum requirement of 23A specified in the manual. Will this have a significant impact?

BG7PUW

BG2GYS In that case, it's possible that the power output is insufficient, even though the battery is fully charged.

BG2GYS

BG7PUW The version with the 30A protection board has a maximum continuous discharge of 30A.

BG5VQE

Full power might not be suitable; instead, choose a 30A protection board.

BG5JKZ

When buying, I use a 30A protection board for my 15Ah battery and a 50A protection board for my 50Ah battery. The important thing is that the chosen board can handle the maximum discharge current.

BG6HFD

I used a lead-acid battery before, and it worked fine. Just connect a small voltmeter to monitor the voltage, but sensitive machines won't run at full power. Set it to 100W, but output around 80-90W. The lithium battery protection board limits the current, so leave some margin according to the specifications on the radio.
