It slots into the same bay as the factory pack and uses the same contact layout. Capacity is rated at 1200mAh (8.88Wh) — identical to the original spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVEV-3288 \/ VEV-3288S \/ V-1000 fit:\u003c\/strong\u003e\n    These three models share the same battery bay dimensions, contact pitch, and 7.4V nominal voltage rail. The BMS on each radio handshakes over the same contact strip, so one pack covers all three without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the VEV-3288 platform. The BMS held cutoff at the correct threshold under PTT transmit load, with no overcurrent trip during sustained keying.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the WEIERWE dock:\u003c\/strong\u003e\n    If the dock LED blinks fault on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The radio's BMS needs a clean contact cycle to accept the new pack before charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVEV-3288 transmit current spike and BMS overcurrent response\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you press PTT, the VEV-3288 pulls a sharp current spike to drive the RF output stage. A new pack at storage voltage — typically around 3.7V per cell — can trigger the BMS overcurrent protection during that spike, cutting the radio mid-transmission. This is not a faulty battery. Once the pack is fully charged to 4.2V per cell, the internal impedance drops and the BMS handles the transmit spike without tripping. Run one full charge cycle before heavy use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe VEV-3288 uses a simple voltage-threshold bar indicator — each bar corresponds to a voltage window. A new cell shipped at storage voltage sits near the bottom of the middle threshold, so the radio reads one bar lower than full. This is normal; the cell is not defective. Charge the pack fully before reading the indicator. After a complete charge to 8.4V across the pack, the indicator should step up to the correct level.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426308718682,"sku":"BWCS-PUX328TW-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426308751450,"sku":"BWCS-PUX328TW-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426308784218,"sku":"BWCS-PUX328TW-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PUX328TW-1.webp?v=1779930681","url":"https:\/\/batteryweb.com\/products\/weierwe-vev-3288-replacement-battery-74v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
