It fits the PM100-DK, PM100II-DK, PM100III-DK, PM200-DK, and related models in the same series. Dimensions are 69.50 × 37.50 × 18.60mm — verify against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePM100 and PM200 series compatibility:\u003c\/strong\u003e\n    These models share the same 7.2V two-cell Li-ion configuration, connector pinout, and BMS handshake protocol. One pack covers the full range listed above without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge-discharge cycles on a PM100-DK unit and monitored BMS cutoff behaviour. The protection circuit tripped correctly at the low-voltage threshold and accepted charge without error flags.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eConnector seating on the PM100-DK:\u003c\/strong\u003e\n    The connector on this series is a snug friction fit — press firmly until you feel it seat. A half-inserted connector causes intermittent signal dropout that looks like a range problem but is actually a power interruption.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the PM100-DK remote loses range before the battery reads as dead\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe IR LED in this remote requires a minimum voltage to fire at full intensity. As the Li-ion pack ages and internal resistance climbs, the voltage sags under load even if the resting voltage looks acceptable. The result is a shorter effective range — the remote works, but only at close distance. Swapping to a fresh pack with low internal resistance restores full IR output. If range has dropped noticeably, measure resting pack voltage: anything below 6.8V under no load points to a degraded cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote completely unresponsive after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe most common cause is reversed polarity — the connector on the PM100 series is physically possible to seat incorrectly if the locking tab is bypassed. Pull the pack out, confirm the positive lead aligns with the marked terminal on the remote's battery bay, and reseat firmly. If polarity is correct and the remote still shows no response, hold any button while reconnecting — some firmware versions require a button press to exit a low-power sleep state after a full power loss. Target voltage on a freshly charged pack is 8.4V before installation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416102961242,"sku":"BWCS-DPM100SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416102994010,"sku":"BWCS-DPM100SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416103026778,"sku":"BWCS-DPM100SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DPM100SL-1.webp?v=1779760263","url":"https:\/\/batteryweb.com\/products\/dam-pm100-dk-replacement-battery-72v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
